Rclone syncs your files to cloud storage

rclone logo

About rclone

Rclone is a command-line program to manage files on cloud storage. It is a feature-rich alternative to cloud vendors' web storage interfaces. Over 70 cloud storage products support rclone including S3 object stores, business & consumer file storage services, as well as standard transfer protocols.

Rclone has powerful cloud equivalents to the unix commands rsync, cp, mv, mount, ls, ncdu, tree, rm, and cat. Rclone's familiar syntax includes shell pipeline support, and --dry-run protection. It is used at the command line, in scripts or via its API.

Users call rclone "The Swiss army knife of cloud storage", and "Technology indistinguishable from magic".

Rclone really looks after your data. It preserves timestamps and verifies checksums at all times. Transfers over limited bandwidth; intermittent connections, or subject to quota can be restarted, from the last good file transferred. You can check the integrity of your files. Where possible, rclone employs server-side transfers to minimise local bandwidth use and transfers from one provider to another without using local disk.

Virtual backends wrap local and cloud file systems to apply encryption, compression, chunking, hashing and joining.

Rclone mounts any local, cloud or virtual filesystem as a disk on Windows, macOS, linux and FreeBSD, and also serves these over SFTP, HTTP, WebDAV, FTP and DLNA.

Rclone is mature, open-source software originally inspired by rsync and written in Go. The friendly support community is familiar with varied use cases. Official Ubuntu, Debian, Fedora, Brew and Chocolatey repos. include rclone. For the latest version downloading from rclone.org is recommended.

Rclone is widely used on Linux, Windows and Mac. Third-party developers create innovative backup, restore, GUI and business process solutions using the rclone command line or API.

Rclone does the heavy lifting of communicating with cloud storage.

What can rclone do for you?

Rclone helps you:

Features

Supported providers

(There are many others, built on standard protocols such as WebDAV or S3, that work out of the box.)

Virtual providers

These backends adapt or modify other storage providers:

Install

Rclone is a Go program and comes as a single binary file.

Quickstart

See below for some expanded Linux / macOS / Windows instructions.

See the usage docs for how to use rclone, or run rclone -h.

Already installed rclone can be easily updated to the latest version using the rclone selfupdate command.

See the release signing docs for how to verify signatures on the release.

Script installation

To install rclone on Linux/macOS/BSD systems, run:

sudo -v ; curl https://rclone.org/install.sh | sudo bash

For beta installation, run:

sudo -v ; curl https://rclone.org/install.sh | sudo bash -s beta

Note that this script checks the version of rclone installed first and won't re-download if not needed.

Linux installation

Precompiled binary

Fetch and unpack

curl -O https://downloads.rclone.org/rclone-current-linux-amd64.zip
unzip rclone-current-linux-amd64.zip
cd rclone-*-linux-amd64

Copy binary file

sudo cp rclone /usr/bin/
sudo chown root:root /usr/bin/rclone
sudo chmod 755 /usr/bin/rclone

Install manpage

sudo mkdir -p /usr/local/share/man/man1
sudo cp rclone.1 /usr/local/share/man/man1/
sudo mandb

Run rclone config to setup. See rclone config docs for more details.

rclone config

macOS installation

Installation with brew

brew install rclone

NOTE: This version of rclone will not support mount any more (see #5373). If mounting is wanted on macOS, either install a precompiled binary or enable the relevant option when installing from source.

Note that this is a third party installer not controlled by the rclone developers so it may be out of date. Its current version is as below.

Homebrew package

Precompiled binary, using curl

To avoid problems with macOS gatekeeper enforcing the binary to be signed and notarized it is enough to download with curl.

Download the latest version of rclone.

cd && curl -O https://downloads.rclone.org/rclone-current-osx-amd64.zip

Unzip the download and cd to the extracted folder.

unzip -a rclone-current-osx-amd64.zip && cd rclone-*-osx-amd64

Move rclone to your $PATH. You will be prompted for your password.

sudo mkdir -p /usr/local/bin
sudo mv rclone /usr/local/bin/

(the mkdir command is safe to run, even if the directory already exists).

Remove the leftover files.

cd .. && rm -rf rclone-*-osx-amd64 rclone-current-osx-amd64.zip

Run rclone config to setup. See rclone config docs for more details.

rclone config

Precompiled binary, using a web browser

When downloading a binary with a web browser, the browser will set the macOS gatekeeper quarantine attribute. Starting from Catalina, when attempting to run rclone, a pop-up will appear saying:

"rclone" cannot be opened because the developer cannot be verified.
macOS cannot verify that this app is free from malware.

The simplest fix is to run

xattr -d com.apple.quarantine rclone

Windows installation

Precompiled binary

Fetch the correct binary for your processor type by clicking on these links. If not sure, use the first link.

Open this file in the Explorer and extract rclone.exe. Rclone is a portable executable so you can place it wherever is convenient.

Open a CMD window (or powershell) and run the binary. Note that rclone does not launch a GUI by default, it runs in the CMD Window.

If you are planning to use the rclone mount feature then you will need to install the third party utility WinFsp also.

Windows package manager (Winget)

Winget comes pre-installed with the latest versions of Windows. If not, update the App Installer package from the Microsoft store.

To install rclone

winget install Rclone.Rclone

To uninstall rclone

winget uninstall Rclone.Rclone --force

Chocolatey package manager

Make sure you have Choco installed

choco search rclone
choco install rclone

This will install rclone on your Windows machine. If you are planning to use rclone mount then

choco install winfsp

will install that too.

Note that this is a third party installer not controlled by the rclone developers so it may be out of date. Its current version is as below.

Chocolatey package

Scoop package manager

Make sure you have Scoop installed

scoop install rclone

Note that this is a third party installer not controlled by the rclone developers so it may be out of date. Its current version is as below.

Scoop package

Package manager installation

Many Linux, Windows, macOS and other OS distributions package and distribute rclone.

The distributed versions of rclone are often quite out of date and for this reason we recommend one of the other installation methods if possible.

You can get an idea of how up to date or not your OS distribution's package is here.

Packaging status

Docker installation

The rclone developers maintain a docker image for rclone.

These images are built as part of the release process based on a minimal Alpine Linux.

The :latest tag will always point to the latest stable release. You can use the :beta tag to get the latest build from master. You can also use version tags, e.g. :1.49.1, :1.49 or :1.

$ docker pull rclone/rclone:latest
latest: Pulling from rclone/rclone
Digest: sha256:0e0ced72671989bb837fea8e88578b3fc48371aa45d209663683e24cfdaa0e11
...
$ docker run --rm rclone/rclone:latest version
rclone v1.49.1
- os/arch: linux/amd64
- go version: go1.12.9

There are a few command line options to consider when starting an rclone Docker container from the rclone image.

Here are some commands tested on an Ubuntu 18.04.3 host:

# config on host at ~/.config/rclone/rclone.conf
# data on host at ~/data

# add a remote interactively
docker run --rm -it \
    --volume ~/.config/rclone:/config/rclone \
    --user $(id -u):$(id -g) \
    rclone/rclone \
    config

# make sure the config is ok by listing the remotes
docker run --rm \
    --volume ~/.config/rclone:/config/rclone \
    --user $(id -u):$(id -g) \
    rclone/rclone \
    listremotes

# perform mount inside Docker container, expose result to host
mkdir -p ~/data/mount
docker run --rm \
    --volume ~/.config/rclone:/config/rclone \
    --volume ~/data:/data:shared \
    --user $(id -u):$(id -g) \
    --volume /etc/passwd:/etc/passwd:ro --volume /etc/group:/etc/group:ro \
    --device /dev/fuse --cap-add SYS_ADMIN --security-opt apparmor:unconfined \
    rclone/rclone \
    mount dropbox:Photos /data/mount &
ls ~/data/mount
kill %1

Snap installation

Get it from the Snap Store

Make sure you have Snapd installed

$ sudo snap install rclone

Due to the strict confinement of Snap, rclone snap cannot acess real /home/$USER/.config/rclone directory, default config path is as below.

Note: Due to the strict confinement of Snap, rclone mount feature is not supported.

If mounting is wanted, either install a precompiled binary or enable the relevant option when installing from source.

Note that this is controlled by community maintainer not the rclone developers so it may be out of date. Its current version is as below.

rclone

Source installation

Make sure you have git and Go installed. Go version 1.17 or newer is required, latest release is recommended. You can get it from your package manager, or download it from golang.org/dl. Then you can run the following:

git clone https://github.com/rclone/rclone.git
cd rclone
go build

This will check out the rclone source in subfolder rclone, which you can later modify and send pull requests with. Then it will build the rclone executable in the same folder. As an initial check you can now run ./rclone version (.\rclone version on Windows).

Note that on macOS and Windows the mount command will not be available unless you specify an additional build tag cmount.

go build -tags cmount

This assumes you have a GCC compatible C compiler (GCC or Clang) in your PATH, as it uses cgo. But on Windows, the cgofuse library that the cmount implementation is based on, also supports building without cgo, i.e. by setting environment variable CGO_ENABLED to value 0 (static linking). This is how the official Windows release of rclone is being built, starting with version 1.59. It is still possible to build with cgo on Windows as well, by using the MinGW port of GCC, e.g. by installing it in a MSYS2 distribution (make sure you install it in the classic mingw64 subsystem, the ucrt64 version is not compatible).

Additionally, on Windows, you must install the third party utility WinFsp, with the "Developer" feature selected. If building with cgo, you must also set environment variable CPATH pointing to the fuse include directory within the WinFsp installation (normally C:\Program Files (x86)\WinFsp\inc\fuse).

You may also add arguments -ldflags -s (with or without -tags cmount), to omit symbol table and debug information, making the executable file smaller, and -trimpath to remove references to local file system paths. This is how the official rclone releases are built.

go build -trimpath -ldflags -s -tags cmount

Instead of executing the go build command directly, you can run it via the Makefile. It changes the version number suffix from "-DEV" to "-beta" and appends commit details. It also copies the resulting rclone executable into your GOPATH bin folder ($(go env GOPATH)/bin, which corresponds to ~/go/bin/rclone by default).

make

To include mount command on macOS and Windows with Makefile build:

make GOTAGS=cmount

There are other make targets that can be used for more advanced builds, such as cross-compiling for all supported os/architectures, embedding icon and version info resources into windows executable, and packaging results into release artifacts. See Makefile and cross-compile.go for details.

Another alternative is to download the source, build and install rclone in one operation, as a regular Go package. The source will be stored it in the Go module cache, and the resulting executable will be in your GOPATH bin folder ($(go env GOPATH)/bin, which corresponds to ~/go/bin/rclone by default).

With Go version 1.17 or newer:

go install github.com/rclone/rclone@latest

With Go versions older than 1.17 (do not use the -u flag, it causes Go to try to update the dependencies that rclone uses and sometimes these don't work with the current version):

go get github.com/rclone/rclone

Ansible installation

This can be done with Stefan Weichinger's ansible role.

Instructions

  1. git clone https://github.com/stefangweichinger/ansible-rclone.git into your local roles-directory
  2. add the role to the hosts you want rclone installed to:
    - hosts: rclone-hosts
      roles:
          - rclone

Portable installation

As mentioned above, rclone is single executable (rclone, or rclone.exe on Windows) that you can download as a zip archive and extract into a location of your choosing. When executing different commands, it may create files in different locations, such as a configuration file and various temporary files. By default the locations for these are according to your operating system, e.g. configuration file in your user profile directory and temporary files in the standard temporary directory, but you can customize all of them, e.g. to make a completely self-contained, portable installation.

Run the config paths command to see the locations that rclone will use.

To override them set the corresponding options (as command-line arguments, or as environment variables): - --config - --cache-dir - --temp-dir

Autostart

After installing and configuring rclone, as described above, you are ready to use rclone as an interactive command line utility. If your goal is to perform periodic operations, such as a regular sync, you will probably want to configure your rclone command in your operating system's scheduler. If you need to expose service-like features, such as remote control, GUI, serve or mount, you will often want an rclone command always running in the background, and configuring it to run in a service infrastructure may be a better option. Below are some alternatives on how to achieve this on different operating systems.

NOTE: Before setting up autorun it is highly recommended that you have tested your command manually from a Command Prompt first.

Autostart on Windows

The most relevant alternatives for autostart on Windows are: - Run at user log on using the Startup folder - Run at user log on, at system startup or at schedule using Task Scheduler - Run at system startup using Windows service

Running in background

Rclone is a console application, so if not starting from an existing Command Prompt, e.g. when starting rclone.exe from a shortcut, it will open a Command Prompt window. When configuring rclone to run from task scheduler and windows service you are able to set it to run hidden in background. From rclone version 1.54 you can also make it run hidden from anywhere by adding option --no-console (it may still flash briefly when the program starts). Since rclone normally writes information and any error messages to the console, you must redirect this to a file to be able to see it. Rclone has a built-in option --log-file for that.

Example command to run a sync in background:

c:\rclone\rclone.exe sync c:\files remote:/files --no-console --log-file c:\rclone\logs\sync_files.txt

User account

As mentioned in the mount documentation, mounted drives created as Administrator are not visible to other accounts, not even the account that was elevated as Administrator. By running the mount command as the built-in SYSTEM user account, it will create drives accessible for everyone on the system. Both scheduled task and Windows service can be used to achieve this.

NOTE: Remember that when rclone runs as the SYSTEM user, the user profile that it sees will not be yours. This means that if you normally run rclone with configuration file in the default location, to be able to use the same configuration when running as the system user you must explicitly tell rclone where to find it with the --config option, or else it will look in the system users profile path (C:\Windows\System32\config\systemprofile). To test your command manually from a Command Prompt, you can run it with the PsExec utility from Microsoft's Sysinternals suite, which takes option -s to execute commands as the SYSTEM user.

Start from Startup folder

To quickly execute an rclone command you can simply create a standard Windows Explorer shortcut for the complete rclone command you want to run. If you store this shortcut in the special "Startup" start-menu folder, Windows will automatically run it at login. To open this folder in Windows Explorer, enter path %APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup, or C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp if you want the command to start for every user that logs in.

This is the easiest approach to autostarting of rclone, but it offers no functionality to set it to run as different user, or to set conditions or actions on certain events. Setting up a scheduled task as described below will often give you better results.

Start from Task Scheduler

Task Scheduler is an administrative tool built into Windows, and it can be used to configure rclone to be started automatically in a highly configurable way, e.g. periodically on a schedule, on user log on, or at system startup. It can run be configured to run as the current user, or for a mount command that needs to be available to all users it can run as the SYSTEM user. For technical information, see https://docs.microsoft.com/windows/win32/taskschd/task-scheduler-start-page.

Run as service

For running rclone at system startup, you can create a Windows service that executes your rclone command, as an alternative to scheduled task configured to run at startup.

Mount command built-in service integration

For mount commands, rclone has a built-in Windows service integration via the third-party WinFsp library it uses. Registering as a regular Windows service easy, as you just have to execute the built-in PowerShell command New-Service (requires administrative privileges).

Example of a PowerShell command that creates a Windows service for mounting some remote:/files as drive letter X:, for all users (service will be running as the local system account):

New-Service -Name Rclone -BinaryPathName 'c:\rclone\rclone.exe mount remote:/files X: --config c:\rclone\config\rclone.conf --log-file c:\rclone\logs\mount.txt'

The WinFsp service infrastructure supports incorporating services for file system implementations, such as rclone, into its own launcher service, as kind of "child services". This has the additional advantage that it also implements a network provider that integrates into Windows standard methods for managing network drives. This is currently not officially supported by Rclone, but with WinFsp version 2019.3 B2 / v1.5B2 or later it should be possible through path rewriting as described here.

Third-party service integration

To Windows service running any rclone command, the excellent third-party utility NSSM, the "Non-Sucking Service Manager", can be used. It includes some advanced features such as adjusting process priority, defining process environment variables, redirect to file anything written to stdout, and customized response to different exit codes, with a GUI to configure everything from (although it can also be used from command line ).

There are also several other alternatives. To mention one more, WinSW, "Windows Service Wrapper", is worth checking out. It requires .NET Framework, but it is preinstalled on newer versions of Windows, and it also provides alternative standalone distributions which includes necessary runtime (.NET 5). WinSW is a command-line only utility, where you have to manually create an XML file with service configuration. This may be a drawback for some, but it can also be an advantage as it is easy to back up and re-use the configuration settings, without having go through manual steps in a GUI. One thing to note is that by default it does not restart the service on error, one have to explicit enable this in the configuration file (via the "onfailure" parameter).

Autostart on Linux

Start as a service

To always run rclone in background, relevant for mount commands etc, you can use systemd to set up rclone as a system or user service. Running as a system service ensures that it is run at startup even if the user it is running as has no active session. Running rclone as a user service ensures that it only starts after the configured user has logged into the system.

Run periodically from cron

To run a periodic command, such as a copy/sync, you can set up a cron job.

Usage

Rclone is a command line program to manage files on cloud storage. After download and install, continue here to learn how to use it: Initial configuration, what the basic syntax looks like, describes the various subcommands, the various options, and more.

Configure

First, you'll need to configure rclone. As the object storage systems have quite complicated authentication these are kept in a config file. (See the --config entry for how to find the config file and choose its location.)

The easiest way to make the config is to run rclone with the config option:

rclone config

See the following for detailed instructions for

Basic syntax

Rclone syncs a directory tree from one storage system to another.

Its syntax is like this

Syntax: [options] subcommand <parameters> <parameters...>

Source and destination paths are specified by the name you gave the storage system in the config file then the sub path, e.g. "drive:myfolder" to look at "myfolder" in Google drive.

You can define as many storage paths as you like in the config file.

Please use the --interactive/-i flag while learning rclone to avoid accidental data loss.

Subcommands

rclone uses a system of subcommands. For example

rclone ls remote:path # lists a remote
rclone copy /local/path remote:path # copies /local/path to the remote
rclone sync --interactive /local/path remote:path # syncs /local/path to the remote

rclone config

Enter an interactive configuration session.

Synopsis

Enter an interactive configuration session where you can setup new remotes and manage existing ones. You may also set or remove a password to protect your configuration.

rclone config [flags]

Options

  -h, --help   help for config

See the global flags page for global options not listed here.

SEE ALSO

rclone copy

Copy files from source to dest, skipping identical files.

Synopsis

Copy the source to the destination. Does not transfer files that are identical on source and destination, testing by size and modification time or MD5SUM. Doesn't delete files from the destination. If you want to also delete files from destination, to make it match source, use the sync command instead.

Note that it is always the contents of the directory that is synced, not the directory itself. So when source:path is a directory, it's the contents of source:path that are copied, not the directory name and contents.

To copy single files, use the copyto command instead.

If dest:path doesn't exist, it is created and the source:path contents go there.

For example

rclone copy source:sourcepath dest:destpath

Let's say there are two files in sourcepath

sourcepath/one.txt
sourcepath/two.txt

This copies them to

destpath/one.txt
destpath/two.txt

Not to

destpath/sourcepath/one.txt
destpath/sourcepath/two.txt

If you are familiar with rsync, rclone always works as if you had written a trailing / - meaning "copy the contents of this directory". This applies to all commands and whether you are talking about the source or destination.

See the --no-traverse option for controlling whether rclone lists the destination directory or not. Supplying this option when copying a small number of files into a large destination can speed transfers up greatly.

For example, if you have many files in /path/to/src but only a few of them change every day, you can copy all the files which have changed recently very efficiently like this:

rclone copy --max-age 24h --no-traverse /path/to/src remote:

Note: Use the -P/--progress flag to view real-time transfer statistics.

Note: Use the --dry-run or the --interactive/-i flag to test without copying anything.

rclone copy source:path dest:path [flags]

rclone sync

Make source and dest identical, modifying destination only.

Synopsis

Sync the source to the destination, changing the destination only. Doesn't transfer files that are identical on source and destination, testing by size and modification time or MD5SUM. Destination is updated to match source, including deleting files if necessary (except duplicate objects, see below). If you don't want to delete files from destination, use the copy command instead.

Important: Since this can cause data loss, test first with the --dry-run or the --interactive/-i flag.

rclone sync --interactive SOURCE remote:DESTINATION

Note that files in the destination won't be deleted if there were any errors at any point. Duplicate objects (files with the same name, on those providers that support it) are also not yet handled.

It is always the contents of the directory that is synced, not the directory itself. So when source:path is a directory, it's the contents of source:path that are copied, not the directory name and contents. See extended explanation in the copy command if unsure.

If dest:path doesn't exist, it is created and the source:path contents go there.

It is not possible to sync overlapping remotes. However, you may exclude the destination from the sync with a filter rule or by putting an exclude-if-present file inside the destination directory and sync to a destination that is inside the source directory.

Note: Use the -P/--progress flag to view real-time transfer statistics

Note: Use the rclone dedupe command to deal with "Duplicate object/directory found in source/destination - ignoring" errors. See this forum post for more info.

rclone move

Move files from source to dest.

Synopsis

Moves the contents of the source directory to the destination directory. Rclone will error if the source and destination overlap and the remote does not support a server-side directory move operation.

To move single files, use the moveto command instead.

If no filters are in use and if possible this will server-side move source:path into dest:path. After this source:path will no longer exist.

Otherwise for each file in source:path selected by the filters (if any) this will move it into dest:path. If possible a server-side move will be used, otherwise it will copy it (server-side if possible) into dest:path then delete the original (if no errors on copy) in source:path.

If you want to delete empty source directories after move, use the --delete-empty-src-dirs flag.

See the --no-traverse option for controlling whether rclone lists the destination directory or not. Supplying this option when moving a small number of files into a large destination can speed transfers up greatly.

Important: Since this can cause data loss, test first with the --dry-run or the --interactive/-i flag.

Note: Use the -P/--progress flag to view real-time transfer statistics.

rclone delete

Remove the files in path.

Synopsis

Remove the files in path. Unlike purge it obeys include/exclude filters so can be used to selectively delete files.

rclone delete only deletes files but leaves the directory structure alone. If you want to delete a directory and all of its contents use the purge command.

If you supply the --rmdirs flag, it will remove all empty directories along with it. You can also use the separate command rmdir or rmdirs to delete empty directories only.

For example, to delete all files bigger than 100 MiB, you may first want to check what would be deleted (use either):

rclone --min-size 100M lsl remote:path
rclone --dry-run --min-size 100M delete remote:path

Then proceed with the actual delete:

rclone --min-size 100M delete remote:path

That reads "delete everything with a minimum size of 100 MiB", hence delete all files bigger than 100 MiB.

Important: Since this can cause data loss, test first with the --dry-run or the --interactive/-i flag.

rclone purge

Remove the path and all of its contents.

Synopsis

Remove the path and all of its contents. Note that this does not obey include/exclude filters - everything will be removed. Use the delete command if you want to selectively delete files. To delete empty directories only, use command rmdir or rmdirs.

Important: Since this can cause data loss, test first with the --dry-run or the --interactive/-i flag.

rclone purge remote:path [flags]

Options

  -h, --help   help for purge

Important Options

Important flags useful for most commands.

  -n, --dry-run         Do a trial run with no permanent changes
  -i, --interactive     Enable interactive mode

rclone rmdir

Remove the empty directory at path.

Synopsis

This removes empty directory given by path. Will not remove the path if it has any objects in it, not even empty subdirectories. Use command rmdirs (or delete with option --rmdirs) to do that.

To delete a path and any objects in it, use purge command.

rclone check

Checks the files in the source and destination match.

Synopsis

Checks the files in the source and destination match. It compares sizes and hashes (MD5 or SHA1) and logs a report of files that don't match. It doesn't alter the source or destination.

For the crypt remote there is a dedicated command, cryptcheck, that are able to check the checksums of the encrypted files.

If you supply the --size-only flag, it will only compare the sizes not the hashes as well. Use this for a quick check.

If you supply the --download flag, it will download the data from both remotes and check them against each other on the fly. This can be useful for remotes that don't support hashes or if you really want to check all the data.

If you supply the --checkfile HASH flag with a valid hash name, the source:path must point to a text file in the SUM format.

If you supply the --one-way flag, it will only check that files in the source match the files in the destination, not the other way around. This means that extra files in the destination that are not in the source will not be detected.

The --differ, --missing-on-dst, --missing-on-src, --match and --error flags write paths, one per line, to the file name (or stdout if it is -) supplied. What they write is described in the help below. For example --differ will write all paths which are present on both the source and destination but different.

The --combined flag will write a file (or stdout) which contains all file paths with a symbol and then a space and then the path to tell you what happened to it. These are reminiscent of diff files.

The default number of parallel checks is 8. See the --checkers=N option for more information.

  -C, --checkfile string        Treat source:path as a SUM file with hashes of given type

rclone md5sum

Produces an md5sum file for all the objects in the path.

Synopsis

Produces an md5sum file for all the objects in the path. This is in the same format as the standard md5sum tool produces.

By default, the hash is requested from the remote. If MD5 is not supported by the remote, no hash will be returned. With the download flag, the file will be downloaded from the remote and hashed locally enabling MD5 for any remote.

For other algorithms, see the hashsum command. Running rclone md5sum remote:path is equivalent to running rclone hashsum MD5 remote:path.

This command can also hash data received on standard input (stdin), by not passing a remote:path, or by passing a hyphen as remote:path when there is data to read (if not, the hyphen will be treated literally, as a relative path).

rclone md5sum remote:path [flags]

Options

      --base64               Output base64 encoded hashsum
  -C, --checkfile string     Validate hashes against a given SUM file instead of printing them
      --download             Download the file and hash it locally; if this flag is not specified, the hash is requested from the remote

rclone sha1sum

Produces an sha1sum file for all the objects in the path.

Synopsis

Produces an sha1sum file for all the objects in the path. This is in the same format as the standard sha1sum tool produces.

By default, the hash is requested from the remote. If SHA-1 is not supported by the remote, no hash will be returned. With the download flag, the file will be downloaded from the remote and hashed locally enabling SHA-1 for any remote.

For other algorithms, see the hashsum command. Running rclone sha1sum remote:path is equivalent to running rclone hashsum SHA1 remote:path.

This command can also hash data received on standard input (stdin), by not passing a remote:path, or by passing a hyphen as remote:path when there is data to read (if not, the hyphen will be treated literally, as a relative path).

This command can also hash data received on STDIN, if not passing a remote:path.

rclone size

Prints the total size and number of objects in remote:path.

Synopsis

Counts objects in the path and calculates the total size. Prints the result to standard output.

By default the output is in human-readable format, but shows values in both human-readable format as well as the raw numbers (global option --human-readable is not considered). Use option --json to format output as JSON instead.

Recurses by default, use --max-depth 1 to stop the recursion.

Some backends do not always provide file sizes, see for example Google Photos and Google Docs. Rclone will then show a notice in the log indicating how many such files were encountered, and count them in as empty files in the output of the size command.

rclone version

Show the version number.

Synopsis

Show the rclone version number, the go version, the build target OS and architecture, the runtime OS and kernel version and bitness, build tags and the type of executable (static or dynamic).

For example:

$ rclone version
rclone v1.55.0

rclone dedupe

Interactively find duplicate filenames and delete/rename them.

Synopsis

By default dedupe interactively finds files with duplicate names and offers to delete all but one or rename them to be different. This is known as deduping by name.

Deduping by name is only useful with a small group of backends (e.g. Google Drive, Opendrive) that can have duplicate file names. It can be run on wrapping backends (e.g. crypt) if they wrap a backend which supports duplicate file names.

However if --by-hash is passed in then dedupe will find files with duplicate hashes instead which will work on any backend which supports at least one hash. This can be used to find files with duplicate content. This is known as deduping by hash.

If deduping by name, first rclone will merge directories with the same name. It will do this iteratively until all the identically named directories have been merged.

Next, if deduping by name, for every group of duplicate file names / hashes, it will delete all but one identical file it finds without confirmation. This means that for most duplicated files the dedupe command will not be interactive.

dedupe considers files to be identical if they have the same file path and the same hash. If the backend does not support hashes (e.g. crypt wrapping Google Drive) then they will never be found to be identical. If you use the --size-only flag then files will be considered identical if they have the same size (any hash will be ignored). This can be useful on crypt backends which do not support hashes.

Next rclone will resolve the remaining duplicates. Exactly which action is taken depends on the dedupe mode. By default, rclone will interactively query the user for each one.

Important: Since this can cause data loss, test first with the --dry-run or the --interactive/-i flag.

Here is an example run.

rclone dedupe --dedupe-mode rename "drive:Google Photos"

Or

rclone dedupe rename "drive:Google Photos"
rclone dedupe [mode] remote:path [flags]

Options

      --by-hash              Find identical hashes rather than names
      --dedupe-mode string   Dedupe mode interactive|skip|first|newest|oldest|largest|smallest|rename (default "interactive")

Synopsis

rclone about prints quota information about a remote to standard output. The output is typically used, free, quota and trash contents.

E.g. Typical output from rclone about remote: is:

Total:   17 GiB
Used:    7.444 GiB
Free:    1.315 GiB
Trashed: 100.000 MiB
Other:   8.241 GiB

Where the fields are:

All sizes are in number of bytes.

Applying a --full flag to the command prints the bytes in full, e.g.

Total:   18253611008
Used:    7993453766
Free:    1411001220
Trashed: 104857602
Other:   8849156022

A --json flag generates conveniently machine-readable output, e.g.

{
    "total": 18253611008,
    "used": 7993453766,
    "trashed": 104857602,
    "other": 8849156022,
    "free": 1411001220

rclone bisync

Perform bidirectional synchronization between two paths.

Synopsis

Perform bidirectional synchronization between two paths.

Bisync provides a bidirectional cloud sync solution in rclone. It retains the Path1 and Path2 filesystem listings from the prior run. On each successive run it will: - list files on Path1 and Path2, and check for changes on each side. Changes include New, Newer, Older, and Deleted files. - Propagate changes on Path1 to Path2, and vice-versa.

See full bisync description for details.

rclone bisync remote1:path1 remote2:path2 [flags]

rclone cat

Concatenates any files and sends them to stdout.

Synopsis

rclone cat sends any files to standard output.

You can use it like this to output a single file

rclone cat remote:path/to/file

Or like this to output any file in dir or its subdirectories.

rclone cat remote:path/to/dir

Or like this to output any .txt files in dir or its subdirectories.

rclone --include "*.txt" cat remote:path/to/dir

Use the --head flag to print characters only at the start, --tail for the end and --offset and --count to print a section in the middle. Note that if offset is negative it will count from the end, so --offset -1 --count 1 is equivalent to --tail 1.

Use the --separator flag to print a separator value between files. Be sure to shell-escape special characters. For example, to print a newline between files, use:

rclone cat remote:path [flags]

Options

      --count int          Only print N characters (default -1)
      --discard            Discard the output instead of printing
      --head int           Only print the first N characters
  -h, --help               help for cat
      --offset int         Start printing at offset N (or from end if -ve)
      --separator string   Separator to use between objects when printing multiple files
      --tail int           Only print the last N characters

rclone checksum

Checks the files in the source against a SUM file.

Synopsis

Checks that hashsums of source files match the SUM file. It compares hashes (MD5, SHA1, etc) and logs a report of files which don't match. It doesn't alter the file system.

If you supply the --download flag, it will download the data from remote and calculate the contents hash on the fly. This can be useful for remotes that don't support hashes or if you really want to check all the data.

Note that hash values in the SUM file are treated as case insensitive.

If you supply the --one-way flag, it will only check that files in the source match the files in the destination, not the other way around. This means that extra files in the destination that are not in the source will not be detected.

The --differ, --missing-on-dst, --missing-on-src, --match and --error flags write paths, one per line, to the file name (or stdout if it is -) supplied. What they write is described in the help below. For example --differ will write all paths which are present on both the source and destination but different.

The --combined flag will write a file (or stdout) which contains all file paths with a symbol and then a space and then the path to tell you what happened to it. These are reminiscent of diff files.

The default number of parallel checks is 8. See the --checkers=N option for more information.

rclone config create

Create a new remote with name, type and options.

Synopsis

Create a new remote of name with type and options. The options should be passed in pairs of key value or as key=value.

For example, to make a swift remote of name myremote using auto config you would do:

rclone config create myremote swift env_auth true
rclone config create myremote swift env_auth=true

So for example if you wanted to configure a Google Drive remote but using remote authorization you would do this:

rclone config create mydrive drive config_is_local=false

Note that if the config process would normally ask a question the default is taken (unless --non-interactive is used). Each time that happens rclone will print or DEBUG a message saying how to affect the value taken.

If any of the parameters passed is a password field, then rclone will automatically obscure them if they aren't already obscured before putting them in the config file.

NB If the password parameter is 22 characters or longer and consists only of base64 characters then rclone can get confused about whether the password is already obscured or not and put unobscured passwords into the config file. If you want to be 100% certain that the passwords get obscured then use the --obscure flag, or if you are 100% certain you are already passing obscured passwords then use --no-obscure. You can also set obscured passwords using the rclone config password command.

The flag --non-interactive is for use by applications that wish to configure rclone themselves, rather than using rclone's text based configuration questions. If this flag is set, and rclone needs to ask the user a question, a JSON blob will be returned with the question in it.

This will look something like (some irrelevant detail removed):

{
    "State": "*oauth-islocal,teamdrive,,",
    "Option": {
        "Name": "config_is_local",
        "Help": "Use web browser to automatically authenticate rclone with remote?\n * Say Y if the machine running rclone has a web browser you can use\n * Say N if running rclone on a (remote) machine without web browser access\nIf not sure try Y. If Y failed, try N.\n",
        "Default": true,
        "Examples": [
            {
                "Value": "true",
                "Help": "Yes"
            },
            {
                "Value": "false",
                "Help": "No"
            }
        ],
        "Required": false,
        "IsPassword": false,
        "Type": "bool",
        "Exclusive": true,
    },
    "Error": "",
}

The format of Option is the same as returned by rclone config providers. The question should be asked to the user and returned to rclone as the --result option along with the --state parameter.

The keys of Option are used as follows:

If Error is set then it should be shown to the user at the same time as the question.

rclone config update name --continue --state "*oauth-islocal,teamdrive,," --result "true"

Note that when using --continue all passwords should be passed in the clear (not obscured). Any default config values should be passed in with each invocation of --continue.

At the end of the non interactive process, rclone will return a result with State as empty string.

If --all is passed then rclone will ask all the config questions, not just the post config questions. Any parameters are used as defaults for questions as usual.

Note that bin/config.py in the rclone source implements this protocol as a readable demonstration.

rclone config create name type [key value]* [flags]

Options

      --all               Ask the full set of config questions
      --continue          Continue the configuration process with an answer
  -h, --help              help for create
      --no-obscure        Force any passwords not to be obscured
      --non-interactive   Don't interact with user and return questions
      --obscure           Force any passwords to be obscured
      --result string     Result - use with --continue

rclone config update

Update options in an existing remote.

Synopsis

Update an existing remote's options. The options should be passed in pairs of key value or as key=value.

For example, to update the env_auth field of a remote of name myremote you would do:

rclone config update myremote env_auth true
rclone config update myremote env_auth=true

If the remote uses OAuth the token will be updated, if you don't require this add an extra parameter thus:

rclone config update myremote env_auth=true config_refresh_token=false

Note that if the config process would normally ask a question the default is taken (unless --non-interactive is used). Each time that happens rclone will print or DEBUG a message saying how to affect the value taken.

If any of the parameters passed is a password field, then rclone will automatically obscure them if they aren't already obscured before putting them in the config file.

NB If the password parameter is 22 characters or longer and consists only of base64 characters then rclone can get confused about whether the password is already obscured or not and put unobscured passwords into the config file. If you want to be 100% certain that the passwords get obscured then use the --obscure flag, or if you are 100% certain you are already passing obscured passwords then use --no-obscure. You can also set obscured passwords using the rclone config password command.

The flag --non-interactive is for use by applications that wish to configure rclone themselves, rather than using rclone's text based configuration questions. If this flag is set, and rclone needs to ask the user a question, a JSON blob will be returned with the question in it.

    "State": "*oauth-islocal,teamdrive,,",
    "Option": {
        "Name": "config_is_local",
        "Help": "Use web browser to automatically authenticate rclone with remote?\n * Say Y if the machine running rclone has a web browser you can use\n * Say N if running rclone on a (remote) machine without web browser access\nIf not sure try Y. If Y failed, try N.\n",
        "Default": true,
        "Examples": [
            {
                "Value": "true",
                "Help": "Yes"
            },
            {
                "Value": "false",
                "Help": "No"
            }
        ],
        "Required": false,
        "IsPassword": false,
        "Type": "bool",
        "Exclusive": true,
    },
    "Error": "",
}

The format of Option is the same as returned by rclone config providers. The question should be asked to the user and returned to rclone as the --result option along with the --state parameter.

The keys of Option are used as follows:

If Error is set then it should be shown to the user at the same time as the question.

rclone config update name --continue --state "*oauth-islocal,teamdrive,," --result "true"

Note that when using --continue all passwords should be passed in the clear (not obscured). Any default config values should be passed in with each invocation of --continue.

At the end of the non interactive process, rclone will return a result with State as empty string.

If --all is passed then rclone will ask all the config questions, not just the post config questions. Any parameters are used as defaults for questions as usual.

Note that bin/config.py in the rclone source implements this protocol as a readable demonstration.

rclone config update name [key value]+ [flags]

Options

      --all               Ask the full set of config questions
      --continue          Continue the configuration process with an answer

      --obscure           Force any passwords to be obscured
      --result string     Result - use with --continue
      --state string      State - use with --continue

rclone copyto

Copy files from source to dest, skipping identical files.

Synopsis

If source:path is a file or directory then it copies it to a file or directory named dest:path.

This can be used to upload single files to other than their current name. If the source is a directory then it acts exactly like the copy command.

So

rclone copyto src dst

where src and dst are rclone paths, either remote:path or /path/to/local or C:.

This will:

if src is file
    copy it to dst, overwriting an existing file if it exists
if src is directory
    copy it to dst, overwriting existing files if they exist
    see copy command for full details

This doesn't transfer files that are identical on src and dst, testing by size and modification time or MD5SUM. It doesn't delete files from the destination.

Note: Use the -P/--progress flag to view real-time transfer statistics

rclone copyurl

Copy url content to dest.

Synopsis

Download a URL's content and copy it to the destination without saving it in temporary storage.

Setting --auto-filename will attempt to automatically determine the filename from the URL (after any redirections) and used in the destination path. With --auto-filename-header in addition, if a specific filename is set in HTTP headers, it will be used instead of the name from the URL. With --print-filename in addition, the resulting file name will be printed.

Setting --no-clobber will prevent overwriting file on the destination if there is one with the same name.

Setting --stdout or making the output file name - will cause the output to be written to standard output.

rclone copyurl https://example.com dest:path [flags]

Options

  -a, --auto-filename     Get the file name from the URL and use it for destination file path
      --header-filename   Get the file name from the Content-Disposition header

rclone cryptcheck

Cryptcheck checks the integrity of an encrypted remote.

Synopsis

rclone cryptcheck checks a remote against a crypted remote. This is the equivalent of running rclone check, but able to check the checksums of the encrypted remote.

For it to work the underlying remote of the cryptedremote must support some kind of checksum.

It works by reading the nonce from each file on the cryptedremote: and using that to encrypt each file on the remote:. It then checks the checksum of the underlying file on the cryptedremote: against the checksum of the file it has just encrypted.

Use it like this

rclone cryptcheck /path/to/files encryptedremote:path

You can use it like this also, but that will involve downloading all the files in remote:path.

rclone cryptcheck remote:path encryptedremote:path

After it has run it will log the status of the encryptedremote:.

If you supply the --one-way flag, it will only check that files in the source match the files in the destination, not the other way around. This means that extra files in the destination that are not in the source will not be detected.

The --differ, --missing-on-dst, --missing-on-src, --match and --error flags write paths, one per line, to the file name (or stdout if it is -) supplied. What they write is described in the help below. For example --differ will write all paths which are present on both the source and destination but different.

The --combined flag will write a file (or stdout) which contains all file paths with a symbol and then a space and then the path to tell you what happened to it. These are reminiscent of diff files.

The default number of parallel checks is 8. See the --checkers=N option for more information.

Options

      --combined string         Make a combined report of changes to this file

rclone hashsum

Produces a hashsum file for all the objects in the path.

Synopsis

Produces a hash file for all the objects in the path using the hash named. The output is in the same format as the standard md5sum/sha1sum tool.

By default, the hash is requested from the remote. If the hash is not supported by the remote, no hash will be returned. With the download flag, the file will be downloaded from the remote and hashed locally enabling any hash for any remote.

For the MD5 and SHA1 algorithms there are also dedicated commands, md5sum and sha1sum.

This command can also hash data received on standard input (stdin), by not passing a remote:path, or by passing a hyphen as remote:path when there is data to read (if not, the hyphen will be treated literally, as a relative path).

Run without a hash to see the list of all supported hashes, e.g.

$ rclone hashsum
Supported hashes are:
  * md5
  * sha1
  * whirlpool
  * crc32
  * sha256
  * dropbox
  * hidrive
  * mailru
  * quickxor

Then

$ rclone hashsum MD5 remote:path

Note that hash names are case insensitive and values are output in lower case.

rclone link

Generate public link to file/folder.

Synopsis

rclone link will create, retrieve or remove a public link to the given file or folder.

rclone link remote:path/to/file
rclone link remote:path/to/folder/
rclone link --unlink remote:path/to/folder/
rclone link --expire 1d remote:path/to/file

If you supply the --expire flag, it will set the expiration time otherwise it will use the default (100 years). Note not all backends support the --expire flag - if the backend doesn't support it then the link returned won't expire.

Use the --unlink flag to remove existing public links to the file or folder. Note not all backends support "--unlink" flag - those that don't will just ignore it.

If successful, the last line of the output will contain the link. Exact capabilities depend on the remote, but the link will always by default be created with the least constraints – e.g. no expiry, no password protection, accessible without account.

rclone link remote:path [flags]

Options

      --expire Duration   The amount of time that the link will be valid (default off)
  -h, --help              help for link
      --unlink            Remove existing public link to file/folder

rclone listremotes

List all the remotes in the config file and defined in environment variables.

Synopsis

rclone listremotes lists all the available remotes from the config file.

When used with the --long flag it lists the types too.

rclone listremotes [flags]

Options

  -h, --help   help for listremotes
      --long   Show the type as well as names

See the global flags page for global options not listed here.

SEE ALSO

rclone lsf

List directories and objects in remote:path formatted for parsing.

Synopsis

List the contents of the source path (directories and objects) to standard output in a form which is easy to parse by scripts. By default this will just be the names of the objects and directories, one per line. The directories will have a / suffix.

Eg

$ rclone lsf swift:bucket
bevajer5jef
canole
diwogej7
ferejej3gux/
fubuwic

Use the --format option to control what gets listed. By default this is just the path, but you can use these parameters to control the output:

p - path
s - size
t - modification time
h - hash
i - ID of object
o - Original ID of underlying object
m - MimeType of object if known
e - encrypted name
T - tier of storage if known, e.g. "Hot" or "Cool"
M - Metadata of object in JSON blob format, eg {"key":"value"}

So if you wanted the path, size and modification time, you would use --format "pst", or maybe --format "tsp" to put the path last.

Eg

$ rclone lsf  --format "tsp" swift:bucket
2016-06-25 18:55:41;60295;bevajer5jef
2016-06-25 18:55:43;90613;canole
2016-06-25 18:55:43;94467;diwogej7
2018-04-26 08:50:45;0;ferejej3gux/
2016-06-25 18:55:40;37600;fubuwic

If you specify "h" in the format you will get the MD5 hash by default, use the --hash flag to change which hash you want. Note that this can be returned as an empty string if it isn't available on the object (and for directories), "ERROR" if there was an error reading it from the object and "UNSUPPORTED" if that object does not support that hash type.

For example, to emulate the md5sum command you can use

rclone lsf -R --hash MD5 --format hp --separator "  " --files-only .

Eg

$ rclone lsf -R --hash MD5 --format hp --separator "  " --files-only swift:bucket
7908e352297f0f530b84a756f188baa3  bevajer5jef
cd65ac234e6fea5925974a51cdd865cc  canole
03b5341b4f234b9d984d03ad076bae91  diwogej7
8fd37c3810dd660778137ac3a66cc06d  fubuwic
99713e14a4c4ff553acaf1930fad985b  gixacuh7ku

(Though "rclone md5sum ." is an easier way of typing this.)

By default the separator is ";" this can be changed with the --separator flag. Note that separators aren't escaped in the path so putting it last is a good strategy.

Eg

$ rclone lsf  --separator "," --format "tshp" swift:bucket
2016-06-25 18:55:41,60295,7908e352297f0f530b84a756f188baa3,bevajer5jef

2016-06-25 18:55:40,37600,8fd37c3810dd660778137ac3a66cc06d,fubuwic

You can output in CSV standard format. This will escape things in " if they contain ,

Eg

$ rclone lsf --csv --files-only --format ps remote:path
test.log,22355
test.sh,449
"this file contains a comma, in the file name.txt",6

Note that the --absolute parameter is useful for making lists of files to pass to an rclone copy with the --files-from-raw flag.

For example, to find all the files modified within one day and copy those only (without traversing the whole directory structure):

rclone lsf --absolute --files-only --max-age 1d /path/to/local > new_files
rclone copy --files-from-raw new_files /path/to/local remote:path

Any of the filtering options can be applied to this command.

There are several related list commands

ls,lsl,lsd are designed to be human-readable. lsf is designed to be human and machine-readable. lsjson is designed to be machine-readable.

Note that ls and lsl recurse by default - use --max-depth 1 to stop the recursion.

The other list commands lsd,lsf,lsjson do not recurse by default - use -R to make them recurse.

Listing a nonexistent directory will produce an error except for remotes which can't have empty directories (e.g. s3, swift, or gcs - the bucket-based remotes).

rclone lsjson

List directories and objects in the path in JSON format.

Synopsis

List directories and objects in the path in JSON format.

The output is an array of Items, where each Item looks like this

{
  "Hashes" : {
     "SHA-1" : "f572d396fae9206628714fb2ce00f72e94f2258f",
     "MD5" : "b1946ac92492d2347c6235b4d2611184",

  },
  "ID": "y2djkhiujf83u33",
  "OrigID": "UYOJVTUW00Q1RzTDA",
  "IsBucket" : false,
  "IsDir" : false,
  "MimeType" : "application/octet-stream",
  "ModTime" : "2017-05-31T16:15:57.034468261+01:00",
  "Name" : "file.txt",
  "Encrypted" : "v0qpsdq8anpci8n929v3uu9338",
  "EncryptedPath" : "kja9098349023498/v0qpsdq8anpci8n929v3uu9338",
  "Path" : "full/path/goes/here/file.txt",
  "Size" : 6,
  "Tier" : "hot",
}

If --hash is not specified the Hashes property won't be emitted. The types of hash can be specified with the --hash-type parameter (which may be repeated). If --hash-type is set then it implies --hash.

If --no-modtime is specified then ModTime will be blank. This can speed things up on remotes where reading the ModTime takes an extra request (e.g. s3, swift).

If --no-mimetype is specified then MimeType will be blank. This can speed things up on remotes where reading the MimeType takes an extra request (e.g. s3, swift).

If --encrypted is not specified the Encrypted won't be emitted.

If --dirs-only is not specified files in addition to directories are returned

If --files-only is not specified directories in addition to the files will be returned.

If --metadata is set then an additional Metadata key will be returned. This will have metadata in rclone standard format as a JSON object.

if --stat is set then a single JSON blob will be returned about the item pointed to. This will return an error if the item isn't found. However on bucket based backends (like s3, gcs, b2, azureblob etc) if the item isn't found it will return an empty directory as it isn't possible to tell empty directories from missing directories there.

The Path field will only show folders below the remote path being listed. If "remote:path" contains the file "subfolder/file.txt", the Path for "file.txt" will be "subfolder/file.txt", not "remote:path/subfolder/file.txt". When used without --recursive the Path will always be the same as Name.

If the directory is a bucket in a bucket-based backend, then "IsBucket" will be set to true. This key won't be present unless it is "true".

The time is in RFC3339 format with up to nanosecond precision. The number of decimal digits in the seconds will depend on the precision that the remote can hold the times, so if times are accurate to the nearest millisecond (e.g. Google Drive) then 3 digits will always be shown ("2017-05-31T16:15:57.034+01:00") whereas if the times are accurate to the nearest second (Dropbox, Box, WebDav, etc.) no digits will be shown ("2017-05-31T16:15:57+01:00").

The whole output can be processed as a JSON blob, or alternatively it can be processed line by line as each item is written one to a line.

Any of the filtering options can be applied to this command.

There are several related list commands

ls,lsl,lsd are designed to be human-readable. lsf is designed to be human and machine-readable. lsjson is designed to be machine-readable.

rclone mount

Mount the remote as file system on a mountpoint.

Synopsis

rclone mount allows Linux, FreeBSD, macOS and Windows to mount any of Rclone's cloud storage systems as a file system with FUSE.

First set up your remote using rclone config. Check it works with rclone ls etc.

On Linux and macOS, you can run mount in either foreground or background (aka daemon) mode. Mount runs in foreground mode by default. Use the --daemon flag to force background mode. On Windows you can run mount in foreground only, the flag is ignored.

In background mode rclone acts as a generic Unix mount program: the main program starts, spawns background rclone process to setup and maintain the mount, waits until success or timeout and exits with appropriate code (killing the child process if it fails).

On Linux/macOS/FreeBSD start the mount like this, where /path/to/local/mount is an empty existing directory:

rclone mount remote:path/to/files /path/to/local/mount

On Windows you can start a mount in different ways. See below for details. If foreground mount is used interactively from a console window, rclone will serve the mount and occupy the console so another window should be used to work with the mount until rclone is interrupted e.g. by pressing Ctrl-C.

The following examples will mount to an automatically assigned drive, to specific drive letter X:, to path C:\path\parent\mount (where parent directory or drive must exist, and mount must not exist, and is not supported when mounting as a network drive), and the last example will mount as network share \\cloud\remote and map it to an automatically assigned drive:

rclone mount remote:path/to/files *
rclone mount remote:path/to/files X:
rclone mount remote:path/to/files C:\path\parent\mount
rclone mount remote:path/to/files \\cloud\remote

When the program ends while in foreground mode, either via Ctrl+C or receiving a SIGINT or SIGTERM signal, the mount should be automatically stopped.

When running in background mode the user will have to stop the mount manually:

# Linux
fusermount -u /path/to/local/mount
# OS X
umount /path/to/local/mount

The umount operation can fail, for example when the mountpoint is busy. When that happens, it is the user's responsibility to stop the mount manually.

The size of the mounted file system will be set according to information retrieved from the remote, the same as returned by the rclone about command. Remotes with unlimited storage may report the used size only, then an additional 1 PiB of free space is assumed. If the remote does not support the about feature at all, then 1 PiB is set as both the total and the free size.

Installing on Windows

To run rclone mount on Windows, you will need to download and install WinFsp.

WinFsp is an open-source Windows File System Proxy which makes it easy to write user space file systems for Windows. It provides a FUSE emulation layer which rclone uses combination with cgofuse. Both of these packages are by Bill Zissimopoulos who was very helpful during the implementation of rclone mount for Windows.

Mounting modes on windows

Unlike other operating systems, Microsoft Windows provides a different filesystem type for network and fixed drives. It optimises access on the assumption fixed disk drives are fast and reliable, while network drives have relatively high latency and less reliability. Some settings can also be differentiated between the two types, for example that Windows Explorer should just display icons and not create preview thumbnails for image and video files on network drives.

In most cases, rclone will mount the remote as a normal, fixed disk drive by default. However, you can also choose to mount it as a remote network drive, often described as a network share. If you mount an rclone remote using the default, fixed drive mode and experience unexpected program errors, freezes or other issues, consider mounting as a network drive instead.

When mounting as a fixed disk drive you can either mount to an unused drive letter, or to a path representing a nonexistent subdirectory of an existing parent directory or drive. Using the special value * will tell rclone to automatically assign the next available drive letter, starting with Z: and moving backward. Examples:

rclone mount remote:path/to/files *
rclone mount remote:path/to/files X:
rclone mount remote:path/to/files C:\path\parent\mount
rclone mount remote:path/to/files X:

Option --volname can be used to set a custom volume name for the mounted file system. The default is to use the remote name and path.

To mount as network drive, you can add option --network-mode to your mount command. Mounting to a directory path is not supported in this mode, it is a limitation Windows imposes on junctions, so the remote must always be mounted to a drive letter.

rclone mount remote:path/to/files X: --network-mode

A volume name specified with --volname will be used to create the network share path. A complete UNC path, such as \\cloud\remote, optionally with path \\cloud\remote\madeup\path, will be used as is. Any other string will be used as the share part, after a default prefix \\server\. If no volume name is specified then \\server\share will be used. You must make sure the volume name is unique when you are mounting more than one drive, or else the mount command will fail. The share name will treated as the volume label for the mapped drive, shown in Windows Explorer etc, while the complete \\server\share will be reported as the remote UNC path by net use etc, just like a normal network drive mapping.

If you specify a full network share UNC path with --volname, this will implicitly set the --network-mode option, so the following two examples have same result:

rclone mount remote:path/to/files X: --network-mode
rclone mount remote:path/to/files X: --volname \\server\share

You may also specify the network share UNC path as the mountpoint itself. Then rclone will automatically assign a drive letter, same as with * and use that as mountpoint, and instead use the UNC path specified as the volume name, as if it were specified with the --volname option. This will also implicitly set the --network-mode option. This means the following two examples have same result:

rclone mount remote:path/to/files \\cloud\remote
rclone mount remote:path/to/files * --volname \\cloud\remote

There is yet another way to enable network mode, and to set the share path, and that is to pass the "native" libfuse/WinFsp option directly: --fuse-flag --VolumePrefix=\server\share. Note that the path must be with just a single backslash prefix in this case.

Note: In previous versions of rclone this was the only supported method.

See also Limitations section below.

Windows filesystem permissions

The FUSE emulation layer on Windows must convert between the POSIX-based permission model used in FUSE, and the permission model used in Windows, based on access-control lists (ACL).

The mounted filesystem will normally get three entries in its access-control list (ACL), representing permissions for the POSIX permission scopes: Owner, group and others. By default, the owner and group will be taken from the current user, and the built-in group "Everyone" will be used to represent others. The user/group can be customized with FUSE options "UserName" and "GroupName", e.g. -o UserName=user123 -o GroupName="Authenticated Users". The permissions on each entry will be set according to options --dir-perms and --file-perms, which takes a value in traditional Unix numeric notation.

The default permissions corresponds to --file-perms 0666 --dir-perms 0777, i.e. read and write permissions to everyone. This means you will not be able to start any programs from the mount. To be able to do that you must add execute permissions, e.g. --file-perms 0777 --dir-perms 0777 to add it to everyone. If the program needs to write files, chances are you will have to enable VFS File Caching as well (see also limitations). Note that the default write permission have some restrictions for accounts other than the owner, specifically it lacks the "write extended attributes", as explained next.

The mapping of permissions is not always trivial, and the result you see in Windows Explorer may not be exactly like you expected. For example, when setting a value that includes write access for the group or others scope, this will be mapped to individual permissions "write attributes", "write data" and "append data", but not "write extended attributes". Windows will then show this as basic permission "Special" instead of "Write", because "Write" also covers the "write extended attributes" permission. When setting digit 0 for group or others, to indicate no permissions, they will still get individual permissions "read attributes", "read extended attributes" and "read permissions". This is done for compatibility reasons, e.g. to allow users without additional permissions to be able to read basic metadata about files like in Unix.

WinFsp 2021 (version 1.9) introduced a new FUSE option "FileSecurity", that allows the complete specification of file security descriptors using SDDL. With this you get detailed control of the resulting permissions, compared to use of the POSIX permissions described above, and no additional permissions will be added automatically for compatibility with Unix. Some example use cases will following.

If you set POSIX permissions for only allowing access to the owner, using --file-perms 0600 --dir-perms 0700, the user group and the built-in "Everyone" group will still be given some special permissions, as described above. Some programs may then (incorrectly) interpret this as the file being accessible by everyone, for example an SSH client may warn about "unprotected private key file". You can work around this by specifying -o FileSecurity="D:P(A;;FA;;;OW)", which sets file all access (FA) to the owner (OW), and nothing else.

When setting write permissions then, except for the owner, this does not include the "write extended attributes" permission, as mentioned above. This may prevent applications from writing to files, giving permission denied error instead. To set working write permissions for the built-in "Everyone" group, similar to what it gets by default but with the addition of the "write extended attributes", you can specify -o FileSecurity="D:P(A;;FRFW;;;WD)", which sets file read (FR) and file write (FW) to everyone (WD). If file execute (FX) is also needed, then change to -o FileSecurity="D:P(A;;FRFWFX;;;WD)", or set file all access (FA) to get full access permissions, including delete, with -o FileSecurity="D:P(A;;FA;;;WD)".

Windows caveats

Drives created as Administrator are not visible to other accounts, not even an account that was elevated to Administrator with the User Account Control (UAC) feature. A result of this is that if you mount to a drive letter from a Command Prompt run as Administrator, and then try to access the same drive from Windows Explorer (which does not run as Administrator), you will not be able to see the mounted drive.

If you don't need to access the drive from applications running with administrative privileges, the easiest way around this is to always create the mount from a non-elevated command prompt.

To make mapped drives available to the user account that created them regardless if elevated or not, there is a special Windows setting called linked connections that can be enabled.

It is also possible to make a drive mount available to everyone on the system, by running the process creating it as the built-in SYSTEM account. There are several ways to do this: One is to use the command-line utility PsExec, from Microsoft's Sysinternals suite, which has option -s to start processes as the SYSTEM account. Another alternative is to run the mount command from a Windows Scheduled Task, or a Windows Service, configured to run as the SYSTEM account. A third alternative is to use the WinFsp.Launcher infrastructure). Read more in the install documentation. Note that when running rclone as another user, it will not use the configuration file from your profile unless you tell it to with the --config option. Note also that it is now the SYSTEM account that will have the owner permissions, and other accounts will have permissions according to the group or others scopes. As mentioned above, these will then not get the "write extended attributes" permission, and this may prevent writing to files. You can work around this with the FileSecurity option, see example above.

Note that mapping to a directory path, instead of a drive letter, does not suffer from the same limitations.

Mounting on macOS

Mounting on macOS can be done either via macFUSE (also known as osxfuse) or FUSE-T. macFUSE is a traditional FUSE driver utilizing a macOS kernel extension (kext). FUSE-T is an alternative FUSE system which "mounts" via an NFSv4 local server.

macFUSE Notes

If installing macFUSE using dmg packages from the website, rclone will locate the macFUSE libraries without any further intervention. If however, macFUSE is installed using the macports package manager, the following addition steps are required.

sudo mkdir /usr/local/lib
cd /usr/local/lib
sudo ln -s /opt/local/lib/libfuse.2.dylib

FUSE-T Limitations, Caveats, and Notes

There are some limitations, caveats, and notes about how it works. These are current as of FUSE-T version 1.0.14.

ModTime update on read

As per the FUSE-T wiki:

File access and modification times cannot be set separately as it seems to be an issue with the NFS client which always modifies both. Can be reproduced with 'touch -m' and 'touch -a' commands

This means that viewing files with various tools, notably macOS Finder, will cause rlcone to update the modification time of the file. This may make rclone upload a full new copy of the file.

Unicode Normalization

Rclone includes flags for unicode normalization with macFUSE that should be updated for FUSE-T. See this forum post and FUSE-T issue #16. The following flag should be added to the rclone mount command.

-o modules=iconv,from_code=UTF-8,to_code=UTF-8

Read Only mounts

When mounting with --read-only, attempts to write to files will fail silently as opposed to with a clear warning as in macFUSE.

Limitations

Without the use of --vfs-cache-mode this can only write files sequentially, it can only seek when reading. This means that many applications won't work with their files on an rclone mount without --vfs-cache-mode writes or --vfs-cache-mode full. See the VFS File Caching section for more info.

The bucket-based remotes (e.g. Swift, S3, Google Compute Storage, B2) do not support the concept of empty directories, so empty directories will have a tendency to disappear once they fall out of the directory cache.

When rclone mount is invoked on Unix with --daemon flag, the main rclone program will wait for the background mount to become ready or until the timeout specified by the --daemon-wait flag. On Linux it can check mount status using ProcFS so the flag in fact sets maximum time to wait, while the real wait can be less. On macOS / BSD the time to wait is constant and the check is performed only at the end. We advise you to set wait time on macOS reasonably.

Only supported on Linux, FreeBSD, OS X and Windows at the moment.

rclone mount vs rclone sync/copy

File systems expect things to be 100% reliable, whereas cloud storage systems are a long way from 100% reliable. The rclone sync/copy commands cope with this with lots of retries. However rclone mount can't use retries in the same way without making local copies of the uploads. Look at the VFS File Caching for solutions to make mount more reliable.

Attribute caching

You can use the flag --attr-timeout to set the time the kernel caches the attributes (size, modification time, etc.) for directory entries.

The default is 1s which caches files just long enough to avoid too many callbacks to rclone from the kernel.

In theory 0s should be the correct value for filesystems which can change outside the control of the kernel. However this causes quite a few problems such as rclone using too much memory, rclone not serving files to samba and excessive time listing directories.

The kernel can cache the info about a file for the time given by --attr-timeout. You may see corruption if the remote file changes length during this window. It will show up as either a truncated file or a file with garbage on the end. With --attr-timeout 1s this is very unlikely but not impossible. The higher you set --attr-timeout the more likely it is. The default setting of "1s" is the lowest setting which mitigates the problems above.

If you set it higher (10s or 1m say) then the kernel will call back to rclone less often making it more efficient, however there is more chance of the corruption issue above.

If files don't change on the remote outside of the control of rclone then there is no chance of corruption.

This is the same as setting the attr_timeout option in mount.fuse.

Filters

Note that all the rclone filters can be used to select a subset of the files to be visible in the mount.

systemd

When running rclone mount as a systemd service, it is possible to use Type=notify. In this case the service will enter the started state after the mountpoint has been successfully set up. Units having the rclone mount service specified as a requirement will see all files and folders immediately in this mode.

Note that systemd runs mount units without any environment variables including PATH or HOME. This means that tilde (~) expansion will not work and you should provide --config and --cache-dir explicitly as absolute paths via rclone arguments. Since mounting requires the fusermount program, rclone will use the fallback PATH of /bin:/usr/bin in this scenario. Please ensure that fusermount is present on this PATH.

Rclone as Unix mount helper

The core Unix program /bin/mount normally takes the -t FSTYPE argument then runs the /sbin/mount.FSTYPE helper program passing it mount options as -o key=val,... or --opt=.... Automount (classic or systemd) behaves in a similar way.

rclone by default expects GNU-style flags --key val. To run it as a mount helper you should symlink rclone binary to /sbin/mount.rclone and optionally /usr/bin/rclonefs, e.g. ln -s /usr/bin/rclone /sbin/mount.rclone. rclone will detect it and translate command-line arguments appropriately.

Now you can run classic mounts like this:

mount sftp1:subdir /mnt/data -t rclone -o vfs_cache_mode=writes,sftp_key_file=/path/to/pem

or create systemd mount units:

# /etc/systemd/system/mnt-data.mount
[Unit]
Description=Mount for /mnt/data
[Mount]
Type=rclone
What=sftp1:subdir
Where=/mnt/data
Options=rw,_netdev,allow_other,args2env,vfs-cache-mode=writes,config=/etc/rclone.conf,cache-dir=/var/rclone

optionally accompanied by systemd automount unit

# /etc/systemd/system/mnt-data.automount
[Unit]
Description=AutoMount for /mnt/data
[Automount]
Where=/mnt/data
TimeoutIdleSec=600
[Install]
WantedBy=multi-user.target

or add in /etc/fstab a line like

sftp1:subdir /mnt/data rclone rw,noauto,nofail,_netdev,x-systemd.automount,args2env,vfs_cache_mode=writes,config=/etc/rclone.conf,cache_dir=/var/cache/rclone 0 0

or use classic Automountd. Remember to provide explicit config=...,cache-dir=... as a workaround for mount units being run without HOME.

Rclone in the mount helper mode will split -o argument(s) by comma, replace _ by - and prepend -- to get the command-line flags. Options containing commas or spaces can be wrapped in single or double quotes. Any inner quotes inside outer quotes of the same type should be doubled.

Mount option syntax includes a few extra options treated specially:

VFS - Virtual File System

This command uses the VFS layer. This adapts the cloud storage objects that rclone uses into something which looks much more like a disk filing system.

Cloud storage objects have lots of properties which aren't like disk files - you can't extend them or write to the middle of them, so the VFS layer has to deal with that. Because there is no one right way of doing this there are various options explained below.

The VFS layer also implements a directory cache - this caches info about files and directories (but not the data) in memory.

VFS Directory Cache

Using the --dir-cache-time flag, you can control how long a directory should be considered up to date and not refreshed from the backend. Changes made through the VFS will appear immediately or invalidate the cache.

--dir-cache-time duration   Time to cache directory entries for (default 5m0s)
--poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)

However, changes made directly on the cloud storage by the web interface or a different copy of rclone will only be picked up once the directory cache expires if the backend configured does not support polling for changes. If the backend supports polling, changes will be picked up within the polling interval.

You can send a SIGHUP signal to rclone for it to flush all directory caches, regardless of how old they are. Assuming only one rclone instance is running, you can reset the cache like this:

kill -SIGHUP $(pidof rclone)

If you configure rclone with a remote control then you can use rclone rc to flush the whole directory cache:

rclone rc vfs/forget

Or individual files or directories:

rclone rc vfs/forget file=path/to/file dir=path/to/dir

VFS File Buffering

The --buffer-size flag determines the amount of memory, that will be used to buffer data in advance.

Each open file will try to keep the specified amount of data in memory at all times. The buffered data is bound to one open file and won't be shared.

This flag is a upper limit for the used memory per open file. The buffer will only use memory for data that is downloaded but not not yet read. If the buffer is empty, only a small amount of memory will be used.

The maximum memory used by rclone for buffering can be up to --buffer-size * open files.

VFS File Caching

These flags control the VFS file caching options. File caching is necessary to make the VFS layer appear compatible with a normal file system. It can be disabled at the cost of some compatibility.

For example you'll need to enable VFS caching if you want to read and write simultaneously to a file. See below for more details.

Note that the VFS cache is separate from the cache backend and you may find that you need one or the other or both.

--cache-dir string                     Directory rclone will use for caching.
--vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
--vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
--vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
--vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
--vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
--vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)

If run with -vv rclone will print the location of the file cache. The files are stored in the user cache file area which is OS dependent but can be controlled with --cache-dir or setting the appropriate environment variable.

The cache has 4 different modes selected by --vfs-cache-mode. The higher the cache mode the more compatible rclone becomes at the cost of using disk space.

Note that files are written back to the remote only when they are closed and if they haven't been accessed for --vfs-write-back seconds. If rclone is quit or dies with files that haven't been uploaded, these will be uploaded next time rclone is run with the same flags.

If using --vfs-cache-max-size or --vfs-cache-min-free-size note that the cache may exceed these quotas for two reasons. Firstly because it is only checked every --vfs-cache-poll-interval. Secondly because open files cannot be evicted from the cache. When --vfs-cache-max-size or --vfs-cache-min-free-size is exceeded, rclone will attempt to evict the least accessed files from the cache first. rclone will start with files that haven't been accessed for the longest. This cache flushing strategy is efficient and more relevant files are likely to remain cached.

The --vfs-cache-max-age will evict files from the cache after the set time since last access has passed. The default value of 1 hour will start evicting files from cache that haven't been accessed for 1 hour. When a cached file is accessed the 1 hour timer is reset to 0 and will wait for 1 more hour before evicting. Specify the time with standard notation, s, m, h, d, w .

You should not run two copies of rclone using the same VFS cache with the same or overlapping remotes if using --vfs-cache-mode > off. This can potentially cause data corruption if you do. You can work around this by giving each rclone its own cache hierarchy with --cache-dir. You don't need to worry about this if the remotes in use don't overlap.

--vfs-cache-mode off

In this mode (the default) the cache will read directly from the remote and write directly to the remote without caching anything on disk.

This will mean some operations are not possible

--vfs-cache-mode minimal

This is very similar to "off" except that files opened for read AND write will be buffered to disk. This means that files opened for write will be a lot more compatible, but uses the minimal disk space.

These operations are not possible

--vfs-cache-mode writes

In this mode files opened for read only are still read directly from the remote, write only and read/write files are buffered to disk first.

This mode should support all normal file system operations.

If an upload fails it will be retried at exponentially increasing intervals up to 1 minute.

--vfs-cache-mode full

In this mode all reads and writes are buffered to and from disk. When data is read from the remote this is buffered to disk as well.

In this mode the files in the cache will be sparse files and rclone will keep track of which bits of the files it has downloaded.

So if an application only reads the starts of each file, then rclone will only buffer the start of the file. These files will appear to be their full size in the cache, but they will be sparse files with only the data that has been downloaded present in them.

This mode should support all normal file system operations and is otherwise identical to --vfs-cache-mode writes.

When reading a file rclone will read --buffer-size plus --vfs-read-ahead bytes ahead. The --buffer-size is buffered in memory whereas the --vfs-read-ahead is buffered on disk.

When using this mode it is recommended that --buffer-size is not set too large and --vfs-read-ahead is set large if required.

IMPORTANT not all file systems support sparse files. In particular FAT/exFAT do not. Rclone will perform very badly if the cache directory is on a filesystem which doesn't support sparse files and it will log an ERROR message if one is detected.

Fingerprinting

Various parts of the VFS use fingerprinting to see if a local file copy has changed relative to a remote file. Fingerprints are made from:

where available on an object.

On some backends some of these attributes are slow to read (they take an extra API call per object, or extra work per object).

For example hash is slow with the local and sftp backends as they have to read the entire file and hash it, and modtime is slow with the s3, swift, ftp and qinqstor backends because they need to do an extra API call to fetch it.

If you use the --vfs-fast-fingerprint flag then rclone will not include the slow operations in the fingerprint. This makes the fingerprinting less accurate but much faster and will improve the opening time of cached files.

If you are running a vfs cache over local, s3 or swift backends then using this flag is recommended.

Note that if you change the value of this flag, the fingerprints of the files in the cache may be invalidated and the files will need to be downloaded again.

VFS Chunked Reading

When rclone reads files from a remote it reads them in chunks. This means that rather than requesting the whole file rclone reads the chunk specified. This can reduce the used download quota for some remotes by requesting only chunks from the remote that are actually read, at the cost of an increased number of requests.

These flags control the chunking:

--vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
--vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)

Rclone will start reading a chunk of size --vfs-read-chunk-size, and then double the size for each read. When --vfs-read-chunk-size-limit is specified, and greater than --vfs-read-chunk-size, the chunk size for each open file will get doubled only until the specified value is reached. If the value is "off", which is the default, the limit is disabled and the chunk size will grow indefinitely.

With --vfs-read-chunk-size 100M and --vfs-read-chunk-size-limit 0 the following parts will be downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When --vfs-read-chunk-size-limit 500M is specified, the result would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so on.

Setting --vfs-read-chunk-size to 0 or "off" disables chunked reading.

VFS Performance

These flags may be used to enable/disable features of the VFS for performance or other reasons. See also the chunked reading feature.

In particular S3 and Swift benefit hugely from the --no-modtime flag (or use --use-server-modtime for a slightly different effect) as each read of the modification time takes a transaction.

--no-checksum     Don't compare checksums on up/download.
--no-modtime      Don't read/write the modification time (can speed things up).
--no-seek         Don't allow seeking in files.
--read-only       Only allow read-only access.

Sometimes rclone is delivered reads or writes out of order. Rather than seeking rclone will wait a short time for the in sequence read or write to come in. These flags only come into effect when not using an on disk cache file.

--vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
--vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)

When using VFS write caching (--vfs-cache-mode with value writes or full), the global flag --transfers can be set to adjust the number of parallel uploads of modified files from the cache (the related global flag --checkers has no effect on the VFS).

--transfers int  Number of file transfers to run in parallel (default 4)

VFS Case Sensitivity

Linux file systems are case-sensitive: two files can differ only by case, and the exact case must be used when opening a file.

File systems in modern Windows are case-insensitive but case-preserving: although existing files can be opened using any case, the exact case used to create the file is preserved and available for programs to query. It is not allowed for two files in the same directory to differ only by case.

Usually file systems on macOS are case-insensitive. It is possible to make macOS file systems case-sensitive but that is not the default.

The --vfs-case-insensitive VFS flag controls how rclone handles these two cases. If its value is "false", rclone passes file names to the remote as-is. If the flag is "true" (or appears without a value on the command line), rclone may perform a "fixup" as explained below.

The user may specify a file name to open/delete/rename/etc with a case different than what is stored on the remote. If an argument refers to an existing file with exactly the same name, then the case of the existing file on the disk will be used. However, if a file name with exactly the same name is not found but a name differing only by case exists, rclone will transparently fixup the name. This fixup happens only when an existing file is requested. Case sensitivity of file names created anew by rclone is controlled by the underlying remote.

Note that case sensitivity of the operating system running rclone (the target) may differ from case sensitivity of a file system presented by rclone (the source). The flag controls whether "fixup" is performed to satisfy the target.

If the flag is not provided on the command line, then its default value depends on the operating system where rclone runs: "true" on Windows and macOS, "false" otherwise. If the flag is provided without a value, then it is "true".

VFS Disk Options

This flag allows you to manually set the statistics about the filing system. It can be useful when those statistics cannot be read correctly automatically.

--vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)

Alternate report of used bytes

Some backends, most notably S3, do not report the amount of bytes used. If you need this information to be available when running df on the filesystem, then pass the flag --vfs-used-is-size to rclone. With this flag set, instead of relying on the backend to report this information, rclone will scan the whole remote similar to rclone size and compute the total used space itself.

WARNING. Contrary to rclone size, this flag ignores filters so that the result is accurate. However, this is very inefficient and may cost lots of API calls resulting in extra charges. Use it as a last resort and only with caching.

rclone moveto

Move file or directory from source to dest.

Synopsis

If source:path is a file or directory then it moves it to a file or directory named dest:path.

This can be used to rename files or upload single files to other than their existing name. If the source is a directory then it acts exactly like the move command.

So

rclone moveto src dst

where src and dst are rclone paths, either remote:path or /path/to/local or C:.

This will:

if src is file
    move it to dst, overwriting an existing file if it exists
if src is directory
    move it to dst, overwriting existing files if they exist
    see move command for full details

This doesn't transfer files that are identical on src and dst, testing by size and modification time or MD5SUM. src will be deleted on successful transfer.

Important: Since this can cause data loss, test first with the --dry-run or the --interactive/-i flag.

Note: Use the -P/--progress flag to view real-time transfer statistics.

rclone ncdu

Explore a remote with a text based user interface.

Synopsis

This displays a text based user interface allowing the navigation of a remote. It is most useful for answering the question - "What is using all my disk space?".

To make the user interface it first scans the entire remote given and builds an in memory representation. rclone ncdu can be used during this scanning phase and you will see it building up the directory structure as it goes along.

You can interact with the user interface using key presses, press '?' to toggle the help on and off. The supported keys are:

 ↑,↓ or k,j to Move
 →,l to enter
 ←,h to return
 g toggle graph
 c toggle counts
 a toggle average size in directory
 m toggle modified time
 u toggle human-readable format
 n,s,C,A,M sort by name,size,count,asize,mtime
 d delete file/directory
 v select file/directory
 V enter visual select mode
 D delete selected files/directories
 y copy current path to clipboard
 Y display current path
 ^L refresh screen (fix screen corruption)
 r recalculate file sizes
 ? to toggle help on and off
 q/ESC/^c to quit

Listed files/directories may be prefixed by a one-character flag, some of them combined with a description in brackets at end of line. These flags have the following meaning:

e means this is an empty directory, i.e. contains no files (but
  may contain empty subdirectories)
~ means this is a directory where some of the files (possibly in
  subdirectories) have unknown size, and therefore the directory
  size may be underestimated (and average size inaccurate, as it
  is average of the files with known sizes).
. means an error occurred while reading a subdirectory, and
  therefore the directory size may be underestimated (and average
  size inaccurate)
! means an error occurred while reading this directory

This an homage to the ncdu tool but for rclone remotes. It is missing lots of features at the moment but is useful as it stands.

Note that it might take some time to delete big files/directories. The UI won't respond in the meantime since the deletion is done synchronously.

For a non-interactive listing of the remote, see the tree command. To just get the total size of the remote you can also use the size command.

rclone obscure

Obscure password for use in the rclone config file.

Synopsis

In the rclone config file, human-readable passwords are obscured. Obscuring them is done by encrypting them and writing them out in base64. This is not a secure way of encrypting these passwords as rclone can decrypt them - it is to prevent "eyedropping" - namely someone seeing a password in the rclone config file by accident.

Many equally important things (like access tokens) are not obscured in the config file. However it is very hard to shoulder surf a 64 character hex token.

This command can also accept a password through STDIN instead of an argument by passing a hyphen as an argument. This will use the first line of STDIN as the password not including the trailing newline.

echo "secretpassword" | rclone obscure -

If there is no data on STDIN to read, rclone obscure will default to obfuscating the hyphen itself.

If you want to encrypt the config file then please use config file encryption - see rclone config for more info.

rclone rc

Run a command against a running rclone.

Synopsis

This runs a command against a running rclone. Use the --url flag to specify an non default URL to connect on. This can be either a ":port" which is taken to mean "http://localhost:port" or a "host:port" which is taken to mean "http://host:port"

A username and password can be passed in with --user and --pass.

Note that --rc-addr, --rc-user, --rc-pass will be read also for --url, --user, --pass.

Arguments should be passed in as parameter=value.

The result will be returned as a JSON object by default.

The --json parameter can be used to pass in a JSON blob as an input instead of key=value arguments. This is the only way of passing in more complicated values.

The -o/--opt option can be used to set a key "opt" with key, value options in the form -o key=value or -o key. It can be repeated as many times as required. This is useful for rc commands which take the "opt" parameter which by convention is a dictionary of strings.

-o key=value -o key2

Will place this in the "opt" value

{"key":"value", "key2","")

The -a/--arg option can be used to set strings in the "arg" value. It can be repeated as many times as required. This is useful for rc commands which take the "arg" parameter which by convention is a list of strings.

-a value -a value2

Will place this in the "arg" value

["value", "value2"]

Use --loopback to connect to the rclone instance running rclone rc. This is very useful for testing commands without having to run an rclone rc server, e.g.:

rclone rc --loopback operations/about fs=/

Use rclone rc to see a list of all possible commands.

SEE ALSO

rclone rcat

Copies standard input to file on remote.

Synopsis

rclone rcat reads from standard input (stdin) and copies it to a single remote file.

echo "hello world" | rclone rcat remote:path/to/file
ffmpeg - | rclone rcat remote:path/to/file

If the remote file already exists, it will be overwritten.

rcat will try to upload small files in a single request, which is usually more efficient than the streaming/chunked upload endpoints, which use multiple requests. Exact behaviour depends on the remote. What is considered a small file may be set through --streaming-upload-cutoff. Uploading only starts after the cutoff is reached or if the file ends before that. The data must fit into RAM. The cutoff needs to be small enough to adhere the limits of your remote, please see there. Generally speaking, setting this cutoff too high will decrease your performance.

Use the --size flag to preallocate the file in advance at the remote end and actually stream it, even if remote backend doesn't support streaming.

--size should be the exact size of the input stream in bytes. If the size of the stream is different in length to the --size passed in then the transfer will likely fail.

Note that the upload cannot be retried because the data is not stored. If the backend supports multipart uploading then individual chunks can be retried. If you need to transfer a lot of data, you may be better off caching it locally and then rclone move it to the destination which can use retries.

  -h, --help       help for rcat

SEE ALSO

rclone rcd

Run rclone listening to remote control commands only.

Synopsis

This runs rclone so that it only listens to remote control commands.

This is useful if you are controlling rclone via the rc API.

If you pass in a path to a directory, rclone will serve that directory for GET requests on the URL passed in. It will also open the URL in the browser when rclone is run.

See the rc documentation for more info on the rc flags.

Server options

Use --rc-addr to specify which IP address and port the server should listen on, eg --rc-addr 1.2.3.4:8000 or --rc-addr :8080 to listen to all IPs. By default it only listens on localhost. You can use port :0 to let the OS choose an available port.

If you set --rc-addr to listen on a public or LAN accessible IP address then using Authentication is advised - see the next section for info.

You can use a unix socket by setting the url to unix:///path/to/socket or just by using an absolute path name. Note that unix sockets bypass the authentication - this is expected to be done with file system permissions.

--rc-addr may be repeated to listen on multiple IPs/ports/sockets.

--rc-server-read-timeout and --rc-server-write-timeout can be used to control the timeouts on the server. Note that this is the total time for a transfer.

--rc-max-header-bytes controls the maximum number of bytes the server will accept in the HTTP header.

--rc-baseurl controls the URL prefix that rclone serves from. By default rclone will serve from the root. If you used --rc-baseurl "/rclone" then rclone would serve from a URL starting with "/rclone/". This is useful if you wish to proxy rclone serve. Rclone automatically inserts leading and trailing "/" on --rc-baseurl, so --rc-baseurl "rclone", --rc-baseurl "/rclone" and --rc-baseurl "/rclone/" are all treated identically.

TLS (SSL)

By default this will serve over http. If you want you can serve over https. You will need to supply the --rc-cert and --rc-key flags. If you wish to do client side certificate validation then you will need to supply --rc-client-ca also.

--rc-cert should be a either a PEM encoded certificate or a concatenation of that with the CA certificate. --krc-ey should be the PEM encoded private key and --rc-client-ca should be the PEM encoded client certificate authority certificate.

--rc-min-tls-version is minimum TLS version that is acceptable. Valid values are "tls1.0", "tls1.1", "tls1.2" and "tls1.3" (default "tls1.0").

Template

--rc-template allows a user to specify a custom markup template for HTTP and WebDAV serve functions. The server exports the following markup to be used within the template to server pages:

Parameter Description
.Name The full path of a file/directory.
.Title Directory listing of .Name
.Sort The current sort used. This is changeable via ?sort= parameter
Sort Options: namedirfirst,name,size,time (default namedirfirst)
.Order The current ordering used. This is changeable via ?order= parameter
Order Options: asc,desc (default asc)
.Query Currently unused.
.Breadcrumb Allows for creating a relative navigation
-- .Link The relative to the root link of the Text.
-- .Text The Name of the directory.
.Entries Information about a specific file/directory.
-- .URL The 'url' of an entry.
-- .Leaf Currently same as 'URL' but intended to be 'just' the name.
-- .IsDir Boolean for if an entry is a directory or not.
-- .Size Size in Bytes of the entry.
-- .ModTime The UTC timestamp of an entry.

Authentication

By default this will serve files without needing a login.

You can either use an htpasswd file which can take lots of users, or set a single username and password with the --rc-user and --rc-pass flags.

If no static users are configured by either of the above methods, and client certificates are required by the --client-ca flag passed to the server, the client certificate common name will be considered as the username.

Use --rc-htpasswd /path/to/htpasswd to provide an htpasswd file. This is in standard apache format and supports MD5, SHA1 and BCrypt for basic authentication. Bcrypt is recommended.

To create an htpasswd file:

touch htpasswd
htpasswd -B htpasswd user
htpasswd -B htpasswd anotherUser

The password file can be updated while rclone is running.

Use --rc-realm to set the authentication realm.

Use --rc-salt to change the password hashing salt from the default.

rclone rmdirs

Remove empty directories under the path.

Synopsis

This recursively removes any empty directories (including directories that only contain empty directories), that it finds under the path. The root path itself will also be removed if it is empty, unless you supply the --leave-root flag.

Use command rmdir to delete just the empty directory given by path, not recurse.

This is useful for tidying up remotes that rclone has left a lot of empty directories in. For example the delete command will delete files but leave the directory structure (unless used with option --rmdirs).

This will delete --checkers directories concurrently so if you have thousands of empty directories consider increasing this number.

To delete a path and any objects in it, use the purge command.

rclone selfupdate

Update the rclone binary.

Synopsis

This command downloads the latest release of rclone and replaces the currently running binary. The download is verified with a hashsum and cryptographically signed signature; see the release signing docs for details.

If used without flags (or with implied --stable flag), this command will install the latest stable release. However, some issues may be fixed (or features added) only in the latest beta release. In such cases you should run the command with the --beta flag, i.e. rclone selfupdate --beta. You can check in advance what version would be installed by adding the --check flag, then repeat the command without it when you are satisfied.

Sometimes the rclone team may recommend you a concrete beta or stable rclone release to troubleshoot your issue or add a bleeding edge feature. The --version VER flag, if given, will update to the concrete version instead of the latest one. If you omit micro version from VER (for example 1.53), the latest matching micro version will be used.

Upon successful update rclone will print a message that contains a previous version number. You will need it if you later decide to revert your update for some reason. Then you'll have to note the previous version and run the following command: rclone selfupdate [--beta] OLDVER. If the old version contains only dots and digits (for example v1.54.0) then it's a stable release so you won't need the --beta flag. Beta releases have an additional information similar to v1.54.0-beta.5111.06f1c0c61. (if you are a developer and use a locally built rclone, the version number will end with -DEV, you will have to rebuild it as it obviously can't be distributed).

If you previously installed rclone via a package manager, the package may include local documentation or configure services. You may wish to update with the flag --package deb or --package rpm (whichever is correct for your OS) to update these too. This command with the default --package zip will update only the rclone executable so the local manual may become inaccurate after it.

The rclone mount command may or may not support extended FUSE options depending on the build and OS. selfupdate will refuse to update if the capability would be discarded.

Note: Windows forbids deletion of a currently running executable so this command will rename the old executable to 'rclone.old.exe' upon success.

Please note that this command was not available before rclone version 1.55. If it fails for you with the message unknown command "selfupdate" then you will need to update manually following the install instructions located at https://rclone.org/install/

SEE ALSO

rclone serve dlna

Serve remote:path over DLNA

Synopsis

Run a DLNA media server for media stored in an rclone remote. Many devices, such as the Xbox and PlayStation, can automatically discover this server in the LAN and play audio/video from it. VLC is also supported. Service discovery uses UDP multicast packets (SSDP) and will thus only work on LANs.

Rclone will list all files present in the remote, without filtering based on media formats or file extensions. Additionally, there is no media transcoding support. This means that some players might show files that they are not able to play back correctly.

Server options

Use --addr to specify which IP address and port the server should listen on, e.g. --addr 1.2.3.4:8000 or --addr :8080 to listen to all IPs.

Use --name to choose the friendly server name, which is by default "rclone (hostname)".

Use --log-trace in conjunction with -vv to enable additional debug logging of all UPNP traffic.

VFS - Virtual File System

This command uses the VFS layer. This adapts the cloud storage objects that rclone uses into something which looks much more like a disk filing system.

Cloud storage objects have lots of properties which aren't like disk files - you can't extend them or write to the middle of them, so the VFS layer has to deal with that. Because there is no one right way of doing this there are various options explained below.

The VFS layer also implements a directory cache - this caches info about files and directories (but not the data) in memory.

VFS Directory Cache

Using the --dir-cache-time flag, you can control how long a directory should be considered up to date and not refreshed from the backend. Changes made through the VFS will appear immediately or invalidate the cache.

--dir-cache-time duration   Time to cache directory entries for (default 5m0s)
--poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)

However, changes made directly on the cloud storage by the web interface or a different copy of rclone will only be picked up once the directory cache expires if the backend configured does not support polling for changes. If the backend supports polling, changes will be picked up within the polling interval.

You can send a SIGHUP signal to rclone for it to flush all directory caches, regardless of how old they are. Assuming only one rclone instance is running, you can reset the cache like this:

kill -SIGHUP $(pidof rclone)

If you configure rclone with a remote control then you can use rclone rc to flush the whole directory cache:

rclone rc vfs/forget

Or individual files or directories:

rclone rc vfs/forget file=path/to/file dir=path/to/dir

VFS File Buffering

The --buffer-size flag determines the amount of memory, that will be used to buffer data in advance.

Each open file will try to keep the specified amount of data in memory at all times. The buffered data is bound to one open file and won't be shared.

This flag is a upper limit for the used memory per open file. The buffer will only use memory for data that is downloaded but not not yet read. If the buffer is empty, only a small amount of memory will be used.

The maximum memory used by rclone for buffering can be up to --buffer-size * open files.

VFS File Caching

These flags control the VFS file caching options. File caching is necessary to make the VFS layer appear compatible with a normal file system. It can be disabled at the cost of some compatibility.

For example you'll need to enable VFS caching if you want to read and write simultaneously to a file. See below for more details.

Note that the VFS cache is separate from the cache backend and you may find that you need one or the other or both.

--cache-dir string                     Directory rclone will use for caching.
--vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
--vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
--vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
--vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
--vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
--vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)

If run with -vv rclone will print the location of the file cache. The files are stored in the user cache file area which is OS dependent but can be controlled with --cache-dir or setting the appropriate environment variable.

The cache has 4 different modes selected by --vfs-cache-mode. The higher the cache mode the more compatible rclone becomes at the cost of using disk space.

Note that files are written back to the remote only when they are closed and if they haven't been accessed for --vfs-write-back seconds. If rclone is quit or dies with files that haven't been uploaded, these will be uploaded next time rclone is run with the same flags.

If using --vfs-cache-max-size or --vfs-cache-min-free-size note that the cache may exceed these quotas for two reasons. Firstly because it is only checked every --vfs-cache-poll-interval. Secondly because open files cannot be evicted from the cache. When --vfs-cache-max-size or --vfs-cache-min-free-size is exceeded, rclone will attempt to evict the least accessed files from the cache first. rclone will start with files that haven't been accessed for the longest. This cache flushing strategy is efficient and more relevant files are likely to remain cached.

The --vfs-cache-max-age will evict files from the cache after the set time since last access has passed. The default value of 1 hour will start evicting files from cache that haven't been accessed for 1 hour. When a cached file is accessed the 1 hour timer is reset to 0 and will wait for 1 more hour before evicting. Specify the time with standard notation, s, m, h, d, w .

You should not run two copies of rclone using the same VFS cache with the same or overlapping remotes if using --vfs-cache-mode > off. This can potentially cause data corruption if you do. You can work around this by giving each rclone its own cache hierarchy with --cache-dir. You don't need to worry about this if the remotes in use don't overlap.

--vfs-cache-mode off

In this mode (the default) the cache will read directly from the remote and write directly to the remote without caching anything on disk.

This will mean some operations are not possible

--vfs-cache-mode minimal

This is very similar to "off" except that files opened for read AND write will be buffered to disk. This means that files opened for write will be a lot more compatible, but uses the minimal disk space.

These operations are not possible

--vfs-cache-mode writes

In this mode files opened for read only are still read directly from the remote, write only and read/write files are buffered to disk first.

This mode should support all normal file system operations.

If an upload fails it will be retried at exponentially increasing intervals up to 1 minute.

--vfs-cache-mode full

In this mode all reads and writes are buffered to and from disk. When data is read from the remote this is buffered to disk as well.

In this mode the files in the cache will be sparse files and rclone will keep track of which bits of the files it has downloaded.

So if an application only reads the starts of each file, then rclone will only buffer the start of the file. These files will appear to be their full size in the cache, but they will be sparse files with only the data that has been downloaded present in them.

This mode should support all normal file system operations and is otherwise identical to --vfs-cache-mode writes.

When reading a file rclone will read --buffer-size plus --vfs-read-ahead bytes ahead. The --buffer-size is buffered in memory whereas the --vfs-read-ahead is buffered on disk.

When using this mode it is recommended that --buffer-size is not set too large and --vfs-read-ahead is set large if required.

IMPORTANT not all file systems support sparse files. In particular FAT/exFAT do not. Rclone will perform very badly if the cache directory is on a filesystem which doesn't support sparse files and it will log an ERROR message if one is detected.

Fingerprinting

Various parts of the VFS use fingerprinting to see if a local file copy has changed relative to a remote file. Fingerprints are made from:

where available on an object.

On some backends some of these attributes are slow to read (they take an extra API call per object, or extra work per object).

For example hash is slow with the local and sftp backends as they have to read the entire file and hash it, and modtime is slow with the s3, swift, ftp and qinqstor backends because they need to do an extra API call to fetch it.

If you use the --vfs-fast-fingerprint flag then rclone will not include the slow operations in the fingerprint. This makes the fingerprinting less accurate but much faster and will improve the opening time of cached files.

If you are running a vfs cache over local, s3 or swift backends then using this flag is recommended.

Note that if you change the value of this flag, the fingerprints of the files in the cache may be invalidated and the files will need to be downloaded again.

VFS Chunked Reading

When rclone reads files from a remote it reads them in chunks. This means that rather than requesting the whole file rclone reads the chunk specified. This can reduce the used download quota for some remotes by requesting only chunks from the remote that are actually read, at the cost of an increased number of requests.

These flags control the chunking:

--vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
--vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)

Rclone will start reading a chunk of size --vfs-read-chunk-size, and then double the size for each read. When --vfs-read-chunk-size-limit is specified, and greater than --vfs-read-chunk-size, the chunk size for each open file will get doubled only until the specified value is reached. If the value is "off", which is the default, the limit is disabled and the chunk size will grow indefinitely.

With --vfs-read-chunk-size 100M and --vfs-read-chunk-size-limit 0 the following parts will be downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When --vfs-read-chunk-size-limit 500M is specified, the result would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so on.

Setting --vfs-read-chunk-size to 0 or "off" disables chunked reading.

VFS Performance

These flags may be used to enable/disable features of the VFS for performance or other reasons. See also the chunked reading feature.

In particular S3 and Swift benefit hugely from the --no-modtime flag (or use --use-server-modtime for a slightly different effect) as each read of the modification time takes a transaction.

--no-checksum     Don't compare checksums on up/download.
--no-modtime      Don't read/write the modification time (can speed things up).
--no-seek         Don't allow seeking in files.
--read-only       Only allow read-only access.

Sometimes rclone is delivered reads or writes out of order. Rather than seeking rclone will wait a short time for the in sequence read or write to come in. These flags only come into effect when not using an on disk cache file.

--vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
--vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)

When using VFS write caching (--vfs-cache-mode with value writes or full), the global flag --transfers can be set to adjust the number of parallel uploads of modified files from the cache (the related global flag --checkers has no effect on the VFS).

--transfers int  Number of file transfers to run in parallel (default 4)

VFS Case Sensitivity

Linux file systems are case-sensitive: two files can differ only by case, and the exact case must be used when opening a file.

File systems in modern Windows are case-insensitive but case-preserving: although existing files can be opened using any case, the exact case used to create the file is preserved and available for programs to query. It is not allowed for two files in the same directory to differ only by case.

Usually file systems on macOS are case-insensitive. It is possible to make macOS file systems case-sensitive but that is not the default.

The --vfs-case-insensitive VFS flag controls how rclone handles these two cases. If its value is "false", rclone passes file names to the remote as-is. If the flag is "true" (or appears without a value on the command line), rclone may perform a "fixup" as explained below.

The user may specify a file name to open/delete/rename/etc with a case different than what is stored on the remote. If an argument refers to an existing file with exactly the same name, then the case of the existing file on the disk will be used. However, if a file name with exactly the same name is not found but a name differing only by case exists, rclone will transparently fixup the name. This fixup happens only when an existing file is requested. Case sensitivity of file names created anew by rclone is controlled by the underlying remote.

Note that case sensitivity of the operating system running rclone (the target) may differ from case sensitivity of a file system presented by rclone (the source). The flag controls whether "fixup" is performed to satisfy the target.

If the flag is not provided on the command line, then its default value depends on the operating system where rclone runs: "true" on Windows and macOS, "false" otherwise. If the flag is provided without a value, then it is "true".

VFS Disk Options

This flag allows you to manually set the statistics about the filing system. It can be useful when those statistics cannot be read correctly automatically.

--vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)

Alternate report of used bytes

Some backends, most notably S3, do not report the amount of bytes used. If you need this information to be available when running df on the filesystem, then pass the flag --vfs-used-is-size to rclone. With this flag set, instead of relying on the backend to report this information, rclone will scan the whole remote similar to rclone size and compute the total used space itself.

WARNING. Contrary to rclone size, this flag ignores filters so that the result is accurate. However, this is very inefficient and may cost lots of API calls resulting in extra charges. Use it as a last resort and only with caching.

rclone serve docker

Serve any remote on docker's volume plugin API.

Synopsis

This command implements the Docker volume plugin API allowing docker to use rclone as a data storage mechanism for various cloud providers. rclone provides docker volume plugin based on it.

To create a docker plugin, one must create a Unix or TCP socket that Docker will look for when you use the plugin and then it listens for commands from docker daemon and runs the corresponding code when necessary. Docker plugins can run as a managed plugin under control of the docker daemon or as an independent native service. For testing, you can just run it directly from the command line, for example:

sudo rclone serve docker --base-dir /tmp/rclone-volumes --socket-addr localhost:8787 -vv

Running rclone serve docker will create the said socket, listening for commands from Docker to create the necessary Volumes. Normally you need not give the --socket-addr flag. The API will listen on the unix domain socket at /run/docker/plugins/rclone.sock. In the example above rclone will create a TCP socket and a small file /etc/docker/plugins/rclone.spec containing the socket address. We use sudo because both paths are writeable only by the root user.

If you later decide to change listening socket, the docker daemon must be restarted to reconnect to /run/docker/plugins/rclone.sock or parse new /etc/docker/plugins/rclone.spec. Until you restart, any volume related docker commands will timeout trying to access the old socket. Running directly is supported on Linux only, not on Windows or MacOS. This is not a problem with managed plugin mode described in details in the full documentation.

The command will create volume mounts under the path given by --base-dir (by default /var/lib/docker-volumes/rclone available only to root) and maintain the JSON formatted file docker-plugin.state in the rclone cache directory with book-keeping records of created and mounted volumes.

All mount and VFS options are submitted by the docker daemon via API, but you can also provide defaults on the command line as well as set path to the config file and cache directory or adjust logging verbosity.

VFS - Virtual File System

This command uses the VFS layer. This adapts the cloud storage objects that rclone uses into something which looks much more like a disk filing system.

Cloud storage objects have lots of properties which aren't like disk files - you can't extend them or write to the middle of them, so the VFS layer has to deal with that. Because there is no one right way of doing this there are various options explained below.

The VFS layer also implements a directory cache - this caches info about files and directories (but not the data) in memory.

VFS Directory Cache

Using the --dir-cache-time flag, you can control how long a directory should be considered up to date and not refreshed from the backend. Changes made through the VFS will appear immediately or invalidate the cache.

--dir-cache-time duration   Time to cache directory entries for (default 5m0s)
--poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)

However, changes made directly on the cloud storage by the web interface or a different copy of rclone will only be picked up once the directory cache expires if the backend configured does not support polling for changes. If the backend supports polling, changes will be picked up within the polling interval.

You can send a SIGHUP signal to rclone for it to flush all directory caches, regardless of how old they are. Assuming only one rclone instance is running, you can reset the cache like this:

kill -SIGHUP $(pidof rclone)

If you configure rclone with a remote control then you can use rclone rc to flush the whole directory cache:

rclone rc vfs/forget

Or individual files or directories:

rclone rc vfs/forget file=path/to/file dir=path/to/dir

VFS File Buffering

The --buffer-size flag determines the amount of memory, that will be used to buffer data in advance.

Each open file will try to keep the specified amount of data in memory at all times. The buffered data is bound to one open file and won't be shared.

This flag is a upper limit for the used memory per open file. The buffer will only use memory for data that is downloaded but not not yet read. If the buffer is empty, only a small amount of memory will be used.

The maximum memory used by rclone for buffering can be up to --buffer-size * open files.

VFS File Caching

These flags control the VFS file caching options. File caching is necessary to make the VFS layer appear compatible with a normal file system. It can be disabled at the cost of some compatibility.

For example you'll need to enable VFS caching if you want to read and write simultaneously to a file. See below for more details.

Note that the VFS cache is separate from the cache backend and you may find that you need one or the other or both.

--cache-dir string                     Directory rclone will use for caching.
--vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
--vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
--vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
--vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
--vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
--vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)

If run with -vv rclone will print the location of the file cache. The files are stored in the user cache file area which is OS dependent but can be controlled with --cache-dir or setting the appropriate environment variable.

The cache has 4 different modes selected by --vfs-cache-mode. The higher the cache mode the more compatible rclone becomes at the cost of using disk space.

Note that files are written back to the remote only when they are closed and if they haven't been accessed for --vfs-write-back seconds. If rclone is quit or dies with files that haven't been uploaded, these will be uploaded next time rclone is run with the same flags.

If using --vfs-cache-max-size or --vfs-cache-min-free-size note that the cache may exceed these quotas for two reasons. Firstly because it is only checked every --vfs-cache-poll-interval. Secondly because open files cannot be evicted from the cache. When --vfs-cache-max-size or --vfs-cache-min-free-size is exceeded, rclone will attempt to evict the least accessed files from the cache first. rclone will start with files that haven't been accessed for the longest. This cache flushing strategy is efficient and more relevant files are likely to remain cached.

The --vfs-cache-max-age will evict files from the cache after the set time since last access has passed. The default value of 1 hour will start evicting files from cache that haven't been accessed for 1 hour. When a cached file is accessed the 1 hour timer is reset to 0 and will wait for 1 more hour before evicting. Specify the time with standard notation, s, m, h, d, w .

You should not run two copies of rclone using the same VFS cache with the same or overlapping remotes if using --vfs-cache-mode > off. This can potentially cause data corruption if you do. You can work around this by giving each rclone its own cache hierarchy with --cache-dir. You don't need to worry about this if the remotes in use don't overlap.

--vfs-cache-mode off

In this mode (the default) the cache will read directly from the remote and write directly to the remote without caching anything on disk.

This will mean some operations are not possible

--vfs-cache-mode minimal

This is very similar to "off" except that files opened for read AND write will be buffered to disk. This means that files opened for write will be a lot more compatible, but uses the minimal disk space.

These operations are not possible

--vfs-cache-mode writes

In this mode files opened for read only are still read directly from the remote, write only and read/write files are buffered to disk first.

This mode should support all normal file system operations.

If an upload fails it will be retried at exponentially increasing intervals up to 1 minute.

--vfs-cache-mode full

In this mode all reads and writes are buffered to and from disk. When data is read from the remote this is buffered to disk as well.

In this mode the files in the cache will be sparse files and rclone will keep track of which bits of the files it has downloaded.

So if an application only reads the starts of each file, then rclone will only buffer the start of the file. These files will appear to be their full size in the cache, but they will be sparse files with only the data that has been downloaded present in them.

This mode should support all normal file system operations and is otherwise identical to --vfs-cache-mode writes.

When reading a file rclone will read --buffer-size plus --vfs-read-ahead bytes ahead. The --buffer-size is buffered in memory whereas the --vfs-read-ahead is buffered on disk.

When using this mode it is recommended that --buffer-size is not set too large and --vfs-read-ahead is set large if required.

IMPORTANT not all file systems support sparse files. In particular FAT/exFAT do not. Rclone will perform very badly if the cache directory is on a filesystem which doesn't support sparse files and it will log an ERROR message if one is detected.

Fingerprinting

Various parts of the VFS use fingerprinting to see if a local file copy has changed relative to a remote file. Fingerprints are made from:

where available on an object.

On some backends some of these attributes are slow to read (they take an extra API call per object, or extra work per object).

For example hash is slow with the local and sftp backends as they have to read the entire file and hash it, and modtime is slow with the s3, swift, ftp and qinqstor backends because they need to do an extra API call to fetch it.

If you use the --vfs-fast-fingerprint flag then rclone will not include the slow operations in the fingerprint. This makes the fingerprinting less accurate but much faster and will improve the opening time of cached files.

If you are running a vfs cache over local, s3 or swift backends then using this flag is recommended.

Note that if you change the value of this flag, the fingerprints of the files in the cache may be invalidated and the files will need to be downloaded again.

VFS Chunked Reading

When rclone reads files from a remote it reads them in chunks. This means that rather than requesting the whole file rclone reads the chunk specified. This can reduce the used download quota for some remotes by requesting only chunks from the remote that are actually read, at the cost of an increased number of requests.

These flags control the chunking:

--vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
--vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)

Rclone will start reading a chunk of size --vfs-read-chunk-size, and then double the size for each read. When --vfs-read-chunk-size-limit is specified, and greater than --vfs-read-chunk-size, the chunk size for each open file will get doubled only until the specified value is reached. If the value is "off", which is the default, the limit is disabled and the chunk size will grow indefinitely.

With --vfs-read-chunk-size 100M and --vfs-read-chunk-size-limit 0 the following parts will be downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When --vfs-read-chunk-size-limit 500M is specified, the result would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so on.

Setting --vfs-read-chunk-size to 0 or "off" disables chunked reading.

VFS Performance

These flags may be used to enable/disable features of the VFS for performance or other reasons. See also the chunked reading feature.

In particular S3 and Swift benefit hugely from the --no-modtime flag (or use --use-server-modtime for a slightly different effect) as each read of the modification time takes a transaction.

--no-checksum     Don't compare checksums on up/download.
--no-modtime      Don't read/write the modification time (can speed things up).
--no-seek         Don't allow seeking in files.
--read-only       Only allow read-only access.

Sometimes rclone is delivered reads or writes out of order. Rather than seeking rclone will wait a short time for the in sequence read or write to come in. These flags only come into effect when not using an on disk cache file.

--vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
--vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)

When using VFS write caching (--vfs-cache-mode with value writes or full), the global flag --transfers can be set to adjust the number of parallel uploads of modified files from the cache (the related global flag --checkers has no effect on the VFS).

--transfers int  Number of file transfers to run in parallel (default 4)

VFS Case Sensitivity

Linux file systems are case-sensitive: two files can differ only by case, and the exact case must be used when opening a file.

File systems in modern Windows are case-insensitive but case-preserving: although existing files can be opened using any case, the exact case used to create the file is preserved and available for programs to query. It is not allowed for two files in the same directory to differ only by case.

Usually file systems on macOS are case-insensitive. It is possible to make macOS file systems case-sensitive but that is not the default.

The --vfs-case-insensitive VFS flag controls how rclone handles these two cases. If its value is "false", rclone passes file names to the remote as-is. If the flag is "true" (or appears without a value on the command line), rclone may perform a "fixup" as explained below.

The user may specify a file name to open/delete/rename/etc with a case different than what is stored on the remote. If an argument refers to an existing file with exactly the same name, then the case of the existing file on the disk will be used. However, if a file name with exactly the same name is not found but a name differing only by case exists, rclone will transparently fixup the name. This fixup happens only when an existing file is requested. Case sensitivity of file names created anew by rclone is controlled by the underlying remote.

Note that case sensitivity of the operating system running rclone (the target) may differ from case sensitivity of a file system presented by rclone (the source). The flag controls whether "fixup" is performed to satisfy the target.

If the flag is not provided on the command line, then its default value depends on the operating system where rclone runs: "true" on Windows and macOS, "false" otherwise. If the flag is provided without a value, then it is "true".

VFS Disk Options

This flag allows you to manually set the statistics about the filing system. It can be useful when those statistics cannot be read correctly automatically.

--vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)

Alternate report of used bytes

Some backends, most notably S3, do not report the amount of bytes used. If you need this information to be available when running df on the filesystem, then pass the flag --vfs-used-is-size to rclone. With this flag set, instead of relying on the backend to report this information, rclone will scan the whole remote similar to rclone size and compute the total used space itself.

WARNING. Contrary to rclone size, this flag ignores filters so that the result is accurate. However, this is very inefficient and may cost lots of API calls resulting in extra charges. Use it as a last resort and only with caching.

rclone serve ftp

Serve remote:path over FTP.

Synopsis

Run a basic FTP server to serve a remote over FTP protocol. This can be viewed with a FTP client or you can make a remote of type FTP to read and write it.

Server options

Use --addr to specify which IP address and port the server should listen on, e.g. --addr 1.2.3.4:8000 or --addr :8080 to listen to all IPs. By default it only listens on localhost. You can use port :0 to let the OS choose an available port.

If you set --addr to listen on a public or LAN accessible IP address then using Authentication is advised - see the next section for info.

Authentication

By default this will serve files without needing a login.

You can set a single username and password with the --user and --pass flags.

VFS - Virtual File System

This command uses the VFS layer. This adapts the cloud storage objects that rclone uses into something which looks much more like a disk filing system.

Cloud storage objects have lots of properties which aren't like disk files - you can't extend them or write to the middle of them, so the VFS layer has to deal with that. Because there is no one right way of doing this there are various options explained below.

The VFS layer also implements a directory cache - this caches info about files and directories (but not the data) in memory.

VFS Directory Cache

Using the --dir-cache-time flag, you can control how long a directory should be considered up to date and not refreshed from the backend. Changes made through the VFS will appear immediately or invalidate the cache.

--dir-cache-time duration   Time to cache directory entries for (default 5m0s)
--poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)

However, changes made directly on the cloud storage by the web interface or a different copy of rclone will only be picked up once the directory cache expires if the backend configured does not support polling for changes. If the backend supports polling, changes will be picked up within the polling interval.

You can send a SIGHUP signal to rclone for it to flush all directory caches, regardless of how old they are. Assuming only one rclone instance is running, you can reset the cache like this:

kill -SIGHUP $(pidof rclone)

If you configure rclone with a remote control then you can use rclone rc to flush the whole directory cache:

rclone rc vfs/forget

Or individual files or directories:

rclone rc vfs/forget file=path/to/file dir=path/to/dir

VFS File Buffering

The --buffer-size flag determines the amount of memory, that will be used to buffer data in advance.

Each open file will try to keep the specified amount of data in memory at all times. The buffered data is bound to one open file and won't be shared.

This flag is a upper limit for the used memory per open file. The buffer will only use memory for data that is downloaded but not not yet read. If the buffer is empty, only a small amount of memory will be used.

The maximum memory used by rclone for buffering can be up to --buffer-size * open files.

VFS File Caching

These flags control the VFS file caching options. File caching is necessary to make the VFS layer appear compatible with a normal file system. It can be disabled at the cost of some compatibility.

For example you'll need to enable VFS caching if you want to read and write simultaneously to a file. See below for more details.

Note that the VFS cache is separate from the cache backend and you may find that you need one or the other or both.

--cache-dir string                     Directory rclone will use for caching.
--vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
--vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
--vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
--vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
--vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
--vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)

If run with -vv rclone will print the location of the file cache. The files are stored in the user cache file area which is OS dependent but can be controlled with --cache-dir or setting the appropriate environment variable.

The cache has 4 different modes selected by --vfs-cache-mode. The higher the cache mode the more compatible rclone becomes at the cost of using disk space.

Note that files are written back to the remote only when they are closed and if they haven't been accessed for --vfs-write-back seconds. If rclone is quit or dies with files that haven't been uploaded, these will be uploaded next time rclone is run with the same flags.

If using --vfs-cache-max-size or --vfs-cache-min-free-size note that the cache may exceed these quotas for two reasons. Firstly because it is only checked every --vfs-cache-poll-interval. Secondly because open files cannot be evicted from the cache. When --vfs-cache-max-size or --vfs-cache-min-free-size is exceeded, rclone will attempt to evict the least accessed files from the cache first. rclone will start with files that haven't been accessed for the longest. This cache flushing strategy is efficient and more relevant files are likely to remain cached.

The --vfs-cache-max-age will evict files from the cache after the set time since last access has passed. The default value of 1 hour will start evicting files from cache that haven't been accessed for 1 hour. When a cached file is accessed the 1 hour timer is reset to 0 and will wait for 1 more hour before evicting. Specify the time with standard notation, s, m, h, d, w .

You should not run two copies of rclone using the same VFS cache with the same or overlapping remotes if using --vfs-cache-mode > off. This can potentially cause data corruption if you do. You can work around this by giving each rclone its own cache hierarchy with --cache-dir. You don't need to worry about this if the remotes in use don't overlap.

--vfs-cache-mode off

In this mode (the default) the cache will read directly from the remote and write directly to the remote without caching anything on disk.

This will mean some operations are not possible

--vfs-cache-mode minimal

This is very similar to "off" except that files opened for read AND write will be buffered to disk. This means that files opened for write will be a lot more compatible, but uses the minimal disk space.

These operations are not possible

--vfs-cache-mode writes

In this mode files opened for read only are still read directly from the remote, write only and read/write files are buffered to disk first.

This mode should support all normal file system operations.

If an upload fails it will be retried at exponentially increasing intervals up to 1 minute.

--vfs-cache-mode full

In this mode all reads and writes are buffered to and from disk. When data is read from the remote this is buffered to disk as well.

In this mode the files in the cache will be sparse files and rclone will keep track of which bits of the files it has downloaded.

So if an application only reads the starts of each file, then rclone will only buffer the start of the file. These files will appear to be their full size in the cache, but they will be sparse files with only the data that has been downloaded present in them.

This mode should support all normal file system operations and is otherwise identical to --vfs-cache-mode writes.

When reading a file rclone will read --buffer-size plus --vfs-read-ahead bytes ahead. The --buffer-size is buffered in memory whereas the --vfs-read-ahead is buffered on disk.

When using this mode it is recommended that --buffer-size is not set too large and --vfs-read-ahead is set large if required.

IMPORTANT not all file systems support sparse files. In particular FAT/exFAT do not. Rclone will perform very badly if the cache directory is on a filesystem which doesn't support sparse files and it will log an ERROR message if one is detected.

Fingerprinting

Various parts of the VFS use fingerprinting to see if a local file copy has changed relative to a remote file. Fingerprints are made from:

where available on an object.

On some backends some of these attributes are slow to read (they take an extra API call per object, or extra work per object).

For example hash is slow with the local and sftp backends as they have to read the entire file and hash it, and modtime is slow with the s3, swift, ftp and qinqstor backends because they need to do an extra API call to fetch it.

If you use the --vfs-fast-fingerprint flag then rclone will not include the slow operations in the fingerprint. This makes the fingerprinting less accurate but much faster and will improve the opening time of cached files.

If you are running a vfs cache over local, s3 or swift backends then using this flag is recommended.

Note that if you change the value of this flag, the fingerprints of the files in the cache may be invalidated and the files will need to be downloaded again.

VFS Chunked Reading

When rclone reads files from a remote it reads them in chunks. This means that rather than requesting the whole file rclone reads the chunk specified. This can reduce the used download quota for some remotes by requesting only chunks from the remote that are actually read, at the cost of an increased number of requests.

These flags control the chunking:

--vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
--vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)

Rclone will start reading a chunk of size --vfs-read-chunk-size, and then double the size for each read. When --vfs-read-chunk-size-limit is specified, and greater than --vfs-read-chunk-size, the chunk size for each open file will get doubled only until the specified value is reached. If the value is "off", which is the default, the limit is disabled and the chunk size will grow indefinitely.

With --vfs-read-chunk-size 100M and --vfs-read-chunk-size-limit 0 the following parts will be downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When --vfs-read-chunk-size-limit 500M is specified, the result would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so on.

Setting --vfs-read-chunk-size to 0 or "off" disables chunked reading.

VFS Performance

These flags may be used to enable/disable features of the VFS for performance or other reasons. See also the chunked reading feature.

In particular S3 and Swift benefit hugely from the --no-modtime flag (or use --use-server-modtime for a slightly different effect) as each read of the modification time takes a transaction.

--no-checksum     Don't compare checksums on up/download.
--no-modtime      Don't read/write the modification time (can speed things up).
--no-seek         Don't allow seeking in files.
--read-only       Only allow read-only access.

Sometimes rclone is delivered reads or writes out of order. Rather than seeking rclone will wait a short time for the in sequence read or write to come in. These flags only come into effect when not using an on disk cache file.

--vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
--vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)

When using VFS write caching (--vfs-cache-mode with value writes or full), the global flag --transfers can be set to adjust the number of parallel uploads of modified files from the cache (the related global flag --checkers has no effect on the VFS).

--transfers int  Number of file transfers to run in parallel (default 4)

VFS Case Sensitivity

Linux file systems are case-sensitive: two files can differ only by case, and the exact case must be used when opening a file.

File systems in modern Windows are case-insensitive but case-preserving: although existing files can be opened using any case, the exact case used to create the file is preserved and available for programs to query. It is not allowed for two files in the same directory to differ only by case.

Usually file systems on macOS are case-insensitive. It is possible to make macOS file systems case-sensitive but that is not the default.

The --vfs-case-insensitive VFS flag controls how rclone handles these two cases. If its value is "false", rclone passes file names to the remote as-is. If the flag is "true" (or appears without a value on the command line), rclone may perform a "fixup" as explained below.

The user may specify a file name to open/delete/rename/etc with a case different than what is stored on the remote. If an argument refers to an existing file with exactly the same name, then the case of the existing file on the disk will be used. However, if a file name with exactly the same name is not found but a name differing only by case exists, rclone will transparently fixup the name. This fixup happens only when an existing file is requested. Case sensitivity of file names created anew by rclone is controlled by the underlying remote.

Note that case sensitivity of the operating system running rclone (the target) may differ from case sensitivity of a file system presented by rclone (the source). The flag controls whether "fixup" is performed to satisfy the target.

If the flag is not provided on the command line, then its default value depends on the operating system where rclone runs: "true" on Windows and macOS, "false" otherwise. If the flag is provided without a value, then it is "true".

VFS Disk Options

This flag allows you to manually set the statistics about the filing system. It can be useful when those statistics cannot be read correctly automatically.

--vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)

Alternate report of used bytes

Some backends, most notably S3, do not report the amount of bytes used. If you need this information to be available when running df on the filesystem, then pass the flag --vfs-used-is-size to rclone. With this flag set, instead of relying on the backend to report this information, rclone will scan the whole remote similar to rclone size and compute the total used space itself.

WARNING. Contrary to rclone size, this flag ignores filters so that the result is accurate. However, this is very inefficient and may cost lots of API calls resulting in extra charges. Use it as a last resort and only with caching.

Auth Proxy

If you supply the parameter --auth-proxy /path/to/program then rclone will use that program to generate backends on the fly which then are used to authenticate incoming requests. This uses a simple JSON based protocol with input on STDIN and output on STDOUT.

PLEASE NOTE: --auth-proxy and --authorized-keys cannot be used together, if --auth-proxy is set the authorized keys option will be ignored.

There is an example program bin/test_proxy.py in the rclone source code.

The program's job is to take a user and pass on the input and turn those into the config for a backend on STDOUT in JSON format. This config will have any default parameters for the backend added, but it won't use configuration from environment variables or command line options - it is the job of the proxy program to make a complete config.

This config generated must have this extra parameter - _root - root to use for the backend

And it may have this parameter - _obscure - comma separated strings for parameters to obscure

If password authentication was used by the client, input to the proxy process (on STDIN) would look similar to this:

{
    "user": "me",
    "pass": "mypassword"
}

If public-key authentication was used by the client, input to the proxy process (on STDIN) would look similar to this:

{
    "user": "me",
    "public_key": "AAAAB3NzaC1yc2EAAAADAQABAAABAQDuwESFdAe14hVS6omeyX7edc...JQdf"
}

And as an example return this on STDOUT

{
    "type": "sftp",
    "_root": "",
    "_obscure": "pass",
    "user": "me",
    "pass": "mypassword",
    "host": "sftp.example.com"
}

This would mean that an SFTP backend would be created on the fly for the user and pass/public_key returned in the output to the host given. Note that since _obscure is set to pass, rclone will obscure the pass parameter before creating the backend (which is required for sftp backends).

The program can manipulate the supplied user in any way, for example to make proxy to many different sftp backends, you could make the user be user@example.com and then set the host to example.com in the output and the user to user. For security you'd probably want to restrict the host to a limited list.

Note that an internal cache is keyed on user so only use that for configuration, don't use pass or public_key. This also means that if a user's password or public-key is changed the cache will need to expire (which takes 5 mins) before it takes effect.

This can be used to build general purpose proxies to any kind of backend that rclone supports.

SEE ALSO

rclone serve http

Serve the remote over HTTP.

Synopsis

Run a basic web server to serve a remote over HTTP. This can be viewed in a web browser or you can make a remote of type http read from it.

You can use the filter flags (e.g. --include, --exclude) to control what is served.

The server will log errors. Use -v to see access logs.

--bwlimit will be respected for file transfers. Use --stats to control the stats printing.

Server options

Use --addr to specify which IP address and port the server should listen on, eg --addr 1.2.3.4:8000 or --addr :8080 to listen to all IPs. By default it only listens on localhost. You can use port :0 to let the OS choose an available port.

If you set --addr to listen on a public or LAN accessible IP address then using Authentication is advised - see the next section for info.

You can use a unix socket by setting the url to unix:///path/to/socket or just by using an absolute path name. Note that unix sockets bypass the authentication - this is expected to be done with file system permissions.

--addr may be repeated to listen on multiple IPs/ports/sockets.

--server-read-timeout and --server-write-timeout can be used to control the timeouts on the server. Note that this is the total time for a transfer.

--max-header-bytes controls the maximum number of bytes the server will accept in the HTTP header.

--baseurl controls the URL prefix that rclone serves from. By default rclone will serve from the root. If you used --baseurl "/rclone" then rclone would serve from a URL starting with "/rclone/". This is useful if you wish to proxy rclone serve. Rclone automatically inserts leading and trailing "/" on --baseurl, so --baseurl "rclone", --baseurl "/rclone" and --baseurl "/rclone/" are all treated identically.

TLS (SSL)

By default this will serve over http. If you want you can serve over https. You will need to supply the --cert and --key flags. If you wish to do client side certificate validation then you will need to supply --client-ca also.

--cert should be a either a PEM encoded certificate or a concatenation of that with the CA certificate. --key should be the PEM encoded private key and --client-ca should be the PEM encoded client certificate authority certificate.

--min-tls-version is minimum TLS version that is acceptable. Valid values are "tls1.0", "tls1.1", "tls1.2" and "tls1.3" (default "tls1.0").

Template

--template allows a user to specify a custom markup template for HTTP and WebDAV serve functions. The server exports the following markup to be used within the template to server pages:

Parameter Description
.Name The full path of a file/directory.
.Title Directory listing of .Name

Authentication

By default this will serve files without needing a login.

You can either use an htpasswd file which can take lots of users, or set a single username and password with the --user and --pass flags.

If no static users are configured by either of the above methods, and client certificates are required by the --client-ca flag passed to the server, the client certificate common name will be considered as the username.

Use --htpasswd /path/to/htpasswd to provide an htpasswd file. This is in standard apache format and supports MD5, SHA1 and BCrypt for basic authentication. Bcrypt is recommended.

To create an htpasswd file:

touch htpasswd
htpasswd -B htpasswd user
htpasswd -B htpasswd anotherUser

The password file can be updated while rclone is running.

Use --realm to set the authentication realm.

Use --salt to change the password hashing salt from the default.

VFS - Virtual File System

This command uses the VFS layer. This adapts the cloud storage objects that rclone uses into something which looks much more like a disk filing system.

Cloud storage objects have lots of properties which aren't like disk files - you can't extend them or write to the middle of them, so the VFS layer has to deal with that. Because there is no one right way of doing this there are various options explained below.

The VFS layer also implements a directory cache - this caches info about files and directories (but not the data) in memory.

VFS Directory Cache

Using the --dir-cache-time flag, you can control how long a directory should be considered up to date and not refreshed from the backend. Changes made through the VFS will appear immediately or invalidate the cache.

--dir-cache-time duration   Time to cache directory entries for (default 5m0s)
--poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)

However, changes made directly on the cloud storage by the web interface or a different copy of rclone will only be picked up once the directory cache expires if the backend configured does not support polling for changes. If the backend supports polling, changes will be picked up within the polling interval.

You can send a SIGHUP signal to rclone for it to flush all directory caches, regardless of how old they are. Assuming only one rclone instance is running, you can reset the cache like this:

kill -SIGHUP $(pidof rclone)

If you configure rclone with a remote control then you can use rclone rc to flush the whole directory cache:

rclone rc vfs/forget

Or individual files or directories:

rclone rc vfs/forget file=path/to/file dir=path/to/dir

VFS File Buffering

The --buffer-size flag determines the amount of memory, that will be used to buffer data in advance.

Each open file will try to keep the specified amount of data in memory at all times. The buffered data is bound to one open file and won't be shared.

This flag is a upper limit for the used memory per open file. The buffer will only use memory for data that is downloaded but not not yet read. If the buffer is empty, only a small amount of memory will be used.

The maximum memory used by rclone for buffering can be up to --buffer-size * open files.

VFS File Caching

These flags control the VFS file caching options. File caching is necessary to make the VFS layer appear compatible with a normal file system. It can be disabled at the cost of some compatibility.

For example you'll need to enable VFS caching if you want to read and write simultaneously to a file. See below for more details.

Note that the VFS cache is separate from the cache backend and you may find that you need one or the other or both.

--cache-dir string                     Directory rclone will use for caching.
--vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
--vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
--vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
--vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
--vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
--vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)

If run with -vv rclone will print the location of the file cache. The files are stored in the user cache file area which is OS dependent but can be controlled with --cache-dir or setting the appropriate environment variable.

The cache has 4 different modes selected by --vfs-cache-mode. The higher the cache mode the more compatible rclone becomes at the cost of using disk space.

Note that files are written back to the remote only when they are closed and if they haven't been accessed for --vfs-write-back seconds. If rclone is quit or dies with files that haven't been uploaded, these will be uploaded next time rclone is run with the same flags.

If using --vfs-cache-max-size or --vfs-cache-min-free-size note that the cache may exceed these quotas for two reasons. Firstly because it is only checked every --vfs-cache-poll-interval. Secondly because open files cannot be evicted from the cache. When --vfs-cache-max-size or --vfs-cache-min-free-size is exceeded, rclone will attempt to evict the least accessed files from the cache first. rclone will start with files that haven't been accessed for the longest. This cache flushing strategy is efficient and more relevant files are likely to remain cached.

The --vfs-cache-max-age will evict files from the cache after the set time since last access has passed. The default value of 1 hour will start evicting files from cache that haven't been accessed for 1 hour. When a cached file is accessed the 1 hour timer is reset to 0 and will wait for 1 more hour before evicting. Specify the time with standard notation, s, m, h, d, w .

You should not run two copies of rclone using the same VFS cache with the same or overlapping remotes if using --vfs-cache-mode > off. This can potentially cause data corruption if you do. You can work around this by giving each rclone its own cache hierarchy with --cache-dir. You don't need to worry about this if the remotes in use don't overlap.

--vfs-cache-mode off

In this mode (the default) the cache will read directly from the remote and write directly to the remote without caching anything on disk.

This will mean some operations are not possible

--vfs-cache-mode minimal

This is very similar to "off" except that files opened for read AND write will be buffered to disk. This means that files opened for write will be a lot more compatible, but uses the minimal disk space.

These operations are not possible

--vfs-cache-mode writes

In this mode files opened for read only are still read directly from the remote, write only and read/write files are buffered to disk first.

This mode should support all normal file system operations.

If an upload fails it will be retried at exponentially increasing intervals up to 1 minute.

--vfs-cache-mode full

In this mode all reads and writes are buffered to and from disk. When data is read from the remote this is buffered to disk as well.

In this mode the files in the cache will be sparse files and rclone will keep track of which bits of the files it has downloaded.

So if an application only reads the starts of each file, then rclone will only buffer the start of the file. These files will appear to be their full size in the cache, but they will be sparse files with only the data that has been downloaded present in them.

This mode should support all normal file system operations and is otherwise identical to --vfs-cache-mode writes.

When reading a file rclone will read --buffer-size plus --vfs-read-ahead bytes ahead. The --buffer-size is buffered in memory whereas the --vfs-read-ahead is buffered on disk.

When using this mode it is recommended that --buffer-size is not set too large and --vfs-read-ahead is set large if required.

IMPORTANT not all file systems support sparse files. In particular FAT/exFAT do not. Rclone will perform very badly if the cache directory is on a filesystem which doesn't support sparse files and it will log an ERROR message if one is detected.

Fingerprinting

Various parts of the VFS use fingerprinting to see if a local file copy has changed relative to a remote file. Fingerprints are made from:

where available on an object.

On some backends some of these attributes are slow to read (they take an extra API call per object, or extra work per object).

For example hash is slow with the local and sftp backends as they have to read the entire file and hash it, and modtime is slow with the s3, swift, ftp and qinqstor backends because they need to do an extra API call to fetch it.

If you use the --vfs-fast-fingerprint flag then rclone will not include the slow operations in the fingerprint. This makes the fingerprinting less accurate but much faster and will improve the opening time of cached files.

If you are running a vfs cache over local, s3 or swift backends then using this flag is recommended.

Note that if you change the value of this flag, the fingerprints of the files in the cache may be invalidated and the files will need to be downloaded again.

VFS Chunked Reading

When rclone reads files from a remote it reads them in chunks. This means that rather than requesting the whole file rclone reads the chunk specified. This can reduce the used download quota for some remotes by requesting only chunks from the remote that are actually read, at the cost of an increased number of requests.

These flags control the chunking:

--vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
--vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)

Rclone will start reading a chunk of size --vfs-read-chunk-size, and then double the size for each read. When --vfs-read-chunk-size-limit is specified, and greater than --vfs-read-chunk-size, the chunk size for each open file will get doubled only until the specified value is reached. If the value is "off", which is the default, the limit is disabled and the chunk size will grow indefinitely.

With --vfs-read-chunk-size 100M and --vfs-read-chunk-size-limit 0 the following parts will be downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When --vfs-read-chunk-size-limit 500M is specified, the result would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so on.

Setting --vfs-read-chunk-size to 0 or "off" disables chunked reading.

VFS Performance

These flags may be used to enable/disable features of the VFS for performance or other reasons. See also the chunked reading feature.

In particular S3 and Swift benefit hugely from the --no-modtime flag (or use --use-server-modtime for a slightly different effect) as each read of the modification time takes a transaction.

--no-checksum     Don't compare checksums on up/download.
--no-modtime      Don't read/write the modification time (can speed things up).
--no-seek         Don't allow seeking in files.
--read-only       Only allow read-only access.

Sometimes rclone is delivered reads or writes out of order. Rather than seeking rclone will wait a short time for the in sequence read or write to come in. These flags only come into effect when not using an on disk cache file.

--vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
--vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)

When using VFS write caching (--vfs-cache-mode with value writes or full), the global flag --transfers can be set to adjust the number of parallel uploads of modified files from the cache (the related global flag --checkers has no effect on the VFS).

--transfers int  Number of file transfers to run in parallel (default 4)

VFS Case Sensitivity

Linux file systems are case-sensitive: two files can differ only by case, and the exact case must be used when opening a file.

File systems in modern Windows are case-insensitive but case-preserving: although existing files can be opened using any case, the exact case used to create the file is preserved and available for programs to query. It is not allowed for two files in the same directory to differ only by case.

Usually file systems on macOS are case-insensitive. It is possible to make macOS file systems case-sensitive but that is not the default.

The --vfs-case-insensitive VFS flag controls how rclone handles these two cases. If its value is "false", rclone passes file names to the remote as-is. If the flag is "true" (or appears without a value on the command line), rclone may perform a "fixup" as explained below.

The user may specify a file name to open/delete/rename/etc with a case different than what is stored on the remote. If an argument refers to an existing file with exactly the same name, then the case of the existing file on the disk will be used. However, if a file name with exactly the same name is not found but a name differing only by case exists, rclone will transparently fixup the name. This fixup happens only when an existing file is requested. Case sensitivity of file names created anew by rclone is controlled by the underlying remote.

Note that case sensitivity of the operating system running rclone (the target) may differ from case sensitivity of a file system presented by rclone (the source). The flag controls whether "fixup" is performed to satisfy the target.

If the flag is not provided on the command line, then its default value depends on the operating system where rclone runs: "true" on Windows and macOS, "false" otherwise. If the flag is provided without a value, then it is "true".

VFS Disk Options

This flag allows you to manually set the statistics about the filing system. It can be useful when those statistics cannot be read correctly automatically.

--vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)

Alternate report of used bytes

Some backends, most notably S3, do not report the amount of bytes used. If you need this information to be available when running df on the filesystem, then pass the flag --vfs-used-is-size to rclone. With this flag set, instead of relying on the backend to report this information, rclone will scan the whole remote similar to rclone size and compute the total used space itself.

WARNING. Contrary to rclone size, this flag ignores filters so that the result is accurate. However, this is very inefficient and may cost lots of API calls resulting in extra charges. Use it as a last resort and only with caching.

Auth Proxy

If you supply the parameter --auth-proxy /path/to/program then rclone will use that program to generate backends on the fly which then are used to authenticate incoming requests. This uses a simple JSON based protocol with input on STDIN and output on STDOUT.

PLEASE NOTE: --auth-proxy and --authorized-keys cannot be used together, if --auth-proxy is set the authorized keys option will be ignored.

There is an example program bin/test_proxy.py in the rclone source code.

The program's job is to take a user and pass on the input and turn those into the config for a backend on STDOUT in JSON format. This config will have any default parameters for the backend added, but it won't use configuration from environment variables or command line options - it is the job of the proxy program to make a complete config.

This config generated must have this extra parameter - _root - root to use for the backend

And it may have this parameter - _obscure - comma separated strings for parameters to obscure

If password authentication was used by the client, input to the proxy process (on STDIN) would look similar to this:

{
    "user": "me",
    "pass": "mypassword"
}

If public-key authentication was used by the client, input to the proxy process (on STDIN) would look similar to this:

{
    "user": "me",
    "public_key": "AAAAB3NzaC1yc2EAAAADAQABAAABAQDuwESFdAe14hVS6omeyX7edc...JQdf"
}

And as an example return this on STDOUT

{
    "type": "sftp",
    "_root": "",
    "_obscure": "pass",
    "user": "me",
    "pass": "mypassword",
    "host": "sftp.example.com"
}

This would mean that an SFTP backend would be created on the fly for the user and pass/public_key returned in the output to the host given. Note that since _obscure is set to pass, rclone will obscure the pass parameter before creating the backend (which is required for sftp backends).

The program can manipulate the supplied user in any way, for example to make proxy to many different sftp backends, you could make the user be user@example.com and then set the host to example.com in the output and the user to user. For security you'd probably want to restrict the host to a limited list.

Note that an internal cache is keyed on user so only use that for configuration, don't use pass or public_key. This also means that if a user's password or public-key is changed the cache will need to expire (which takes 5 mins) before it takes effect.

This can be used to build general purpose proxies to any kind of backend that rclone supports.

rclone serve restic

Serve the remote for restic's REST API.

Synopsis

Run a basic web server to serve a remote over restic's REST backend API over HTTP. This allows restic to use rclone as a data storage mechanism for cloud providers that restic does not support directly.

Restic is a command-line program for doing backups.

The server will log errors. Use -v to see access logs.

--bwlimit will be respected for file transfers. Use --stats to control the stats printing.

Setting up rclone for use by restic

First set up a remote for your chosen cloud provider.

Once you have set up the remote, check it is working with, for example "rclone lsd remote:". You may have called the remote something other than "remote:" - just substitute whatever you called it in the following instructions.

Now start the rclone restic server

rclone serve restic -v remote:backup

Where you can replace "backup" in the above by whatever path in the remote you wish to use.

By default this will serve on "localhost:8080" you can change this with use of the --addr flag.

You might wish to start this server on boot.

Adding --cache-objects=false will cause rclone to stop caching objects returned from the List call. Caching is normally desirable as it speeds up downloading objects, saves transactions and uses very little memory.

Setting up restic to use rclone

Now you can follow the restic instructions on setting up restic.

Note that you will need restic 0.8.2 or later to interoperate with rclone.

For the example above you will want to use "http://localhost:8080/" as the URL for the REST server.

For example:

$ export RESTIC_REPOSITORY=rest:http://localhost:8080/
$ export RESTIC_PASSWORD=yourpassword
$ restic init
created restic backend 8b1a4b56ae at rest:http://localhost:8080/

Please note that knowledge of your password is required to access
the repository. Losing your password means that your data is
irrecoverably lost.
$ restic backup /path/to/files/to/backup
scan [/path/to/files/to/backup]
scanned 189 directories, 312 files in 0:00
[0:00] 100.00%  38.128 MiB / 38.128 MiB  501 / 501 items  0 errors  ETA 0:00
duration: 0:00
snapshot 45c8fdd8 saved

Multiple repositories

Note that you can use the endpoint to host multiple repositories. Do this by adding a directory name or path after the URL. Note that these must end with /. Eg

$ export RESTIC_REPOSITORY=rest:http://localhost:8080/user1repo/
# backup user1 stuff
$ export RESTIC_REPOSITORY=rest:http://localhost:8080/user2repo/
# backup user2 stuff

Private repositories

The--private-repos flag can be used to limit users to repositories starting with a path of /<username>/.

Server options

Use --addr to specify which IP address and port the server should listen on, eg --addr 1.2.3.4:8000 or --addr :8080 to listen to all IPs. By default it only listens on localhost. You can use port :0 to let the OS choose an available port.

If you set --addr to listen on a public or LAN accessible IP address then using Authentication is advised - see the next section for info.

You can use a unix socket by setting the url to unix:///path/to/socket or just by using an absolute path name. Note that unix sockets bypass the authentication - this is expected to be done with file system permissions.

--addr may be repeated to listen on multiple IPs/ports/sockets.

--server-read-timeout and --server-write-timeout can be used to control the timeouts on the server. Note that this is the total time for a transfer.

--max-header-bytes controls the maximum number of bytes the server will accept in the HTTP header.

--baseurl controls the URL prefix that rclone serves from. By default rclone will serve from the root. If you used --baseurl "/rclone" then rclone would serve from a URL starting with "/rclone/". This is useful if you wish to proxy rclone serve. Rclone automatically inserts leading and trailing "/" on --baseurl, so --baseurl "rclone", --baseurl "/rclone" and --baseurl "/rclone/" are all treated identically.

TLS (SSL)

By default this will serve over http. If you want you can serve over https. You will need to supply the --cert and --key flags. If you wish to do client side certificate validation then you will need to supply --client-ca also.

--cert should be a either a PEM encoded certificate or a concatenation of that with the CA certificate. --key should be the PEM encoded private key and --client-ca should be the PEM encoded client certificate authority certificate.

--min-tls-version is minimum TLS version that is acceptable. Valid values are "tls1.0", "tls1.1", "tls1.2" and "tls1.3" (default "tls1.0").

Authentication

By default this will serve files without needing a login.

You can either use an htpasswd file which can take lots of users, or set a single username and password with the --user and --pass flags.

If no static users are configured by either of the above methods, and client certificates are required by the --client-ca flag passed to the server, the client certificate common name will be considered as the username.

Use --htpasswd /path/to/htpasswd to provide an htpasswd file. This is in standard apache format and supports MD5, SHA1 and BCrypt for basic authentication. Bcrypt is recommended.

To create an htpasswd file:

touch htpasswd
htpasswd -B htpasswd user
htpasswd -B htpasswd anotherUser

The password file can be updated while rclone is running.

Use --realm to set the authentication realm.

Use --salt to change the password hashing salt from the default.

rclone serve sftp

Serve the remote over SFTP.

Synopsis

Run an SFTP server to serve a remote over SFTP. This can be used with an SFTP client or you can make a remote of type sftp to use with it.

You can use the filter flags (e.g. --include, --exclude) to control what is served.

The server will respond to a small number of shell commands, mainly md5sum, sha1sum and df, which enable it to provide support for checksums and the about feature when accessed from an sftp remote.

Note that this server uses standard 32 KiB packet payload size, which means you must not configure the client to expect anything else, e.g. with the chunk_size option on an sftp remote.

The server will log errors. Use -v to see access logs.

--bwlimit will be respected for file transfers. Use --stats to control the stats printing.

You must provide some means of authentication, either with --user/--pass, an authorized keys file (specify location with --authorized-keys - the default is the same as ssh), an --auth-proxy, or set the --no-auth flag for no authentication when logging in.

If you don't supply a host --key then rclone will generate rsa, ecdsa and ed25519 variants, and cache them for later use in rclone's cache directory (see rclone help flags cache-dir) in the "serve-sftp" directory.

By default the server binds to localhost:2022 - if you want it to be reachable externally then supply --addr :2022 for example.

Note that the default of --vfs-cache-mode off is fine for the rclone sftp backend, but it may not be with other SFTP clients.

If --stdio is specified, rclone will serve SFTP over stdio, which can be used with sshd via ~/.ssh/authorized_keys, for example:

restrict,command="rclone serve sftp --stdio ./photos" ssh-rsa ...

On the client you need to set --transfers 1 when using --stdio. Otherwise multiple instances of the rclone server are started by OpenSSH which can lead to "corrupted on transfer" errors. This is the case because the client chooses indiscriminately which server to send commands to while the servers all have different views of the state of the filing system.

The "restrict" in authorized_keys prevents SHA1SUMs and MD5SUMs from being used. Omitting "restrict" and using --sftp-path-override to enable checksumming is possible but less secure and you could use the SFTP server provided by OpenSSH in this case.

VFS - Virtual File System

This command uses the VFS layer. This adapts the cloud storage objects that rclone uses into something which looks much more like a disk filing system.

Cloud storage objects have lots of properties which aren't like disk files - you can't extend them or write to the middle of them, so the VFS layer has to deal with that. Because there is no one right way of doing this there are various options explained below.

The VFS layer also implements a directory cache - this caches info about files and directories (but not the data) in memory.

VFS Directory Cache

Using the --dir-cache-time flag, you can control how long a directory should be considered up to date and not refreshed from the backend. Changes made through the VFS will appear immediately or invalidate the cache.

--dir-cache-time duration   Time to cache directory entries for (default 5m0s)
--poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)

However, changes made directly on the cloud storage by the web interface or a different copy of rclone will only be picked up once the directory cache expires if the backend configured does not support polling for changes. If the backend supports polling, changes will be picked up within the polling interval.

You can send a SIGHUP signal to rclone for it to flush all directory caches, regardless of how old they are. Assuming only one rclone instance is running, you can reset the cache like this:

kill -SIGHUP $(pidof rclone)

If you configure rclone with a remote control then you can use rclone rc to flush the whole directory cache:

rclone rc vfs/forget

Or individual files or directories:

rclone rc vfs/forget file=path/to/file dir=path/to/dir

VFS File Buffering

The --buffer-size flag determines the amount of memory, that will be used to buffer data in advance.

Each open file will try to keep the specified amount of data in memory at all times. The buffered data is bound to one open file and won't be shared.

This flag is a upper limit for the used memory per open file. The buffer will only use memory for data that is downloaded but not not yet read. If the buffer is empty, only a small amount of memory will be used.

The maximum memory used by rclone for buffering can be up to --buffer-size * open files.

VFS File Caching

These flags control the VFS file caching options. File caching is necessary to make the VFS layer appear compatible with a normal file system. It can be disabled at the cost of some compatibility.

For example you'll need to enable VFS caching if you want to read and write simultaneously to a file. See below for more details.

Note that the VFS cache is separate from the cache backend and you may find that you need one or the other or both.

--cache-dir string                     Directory rclone will use for caching.
--vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
--vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
--vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
--vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
--vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
--vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)

If run with -vv rclone will print the location of the file cache. The files are stored in the user cache file area which is OS dependent but can be controlled with --cache-dir or setting the appropriate environment variable.

The cache has 4 different modes selected by --vfs-cache-mode. The higher the cache mode the more compatible rclone becomes at the cost of using disk space.

Note that files are written back to the remote only when they are closed and if they haven't been accessed for --vfs-write-back seconds. If rclone is quit or dies with files that haven't been uploaded, these will be uploaded next time rclone is run with the same flags.

If using --vfs-cache-max-size or --vfs-cache-min-free-size note that the cache may exceed these quotas for two reasons. Firstly because it is only checked every --vfs-cache-poll-interval. Secondly because open files cannot be evicted from the cache. When --vfs-cache-max-size or --vfs-cache-min-free-size is exceeded, rclone will attempt to evict the least accessed files from the cache first. rclone will start with files that haven't been accessed for the longest. This cache flushing strategy is efficient and more relevant files are likely to remain cached.

The --vfs-cache-max-age will evict files from the cache after the set time since last access has passed. The default value of 1 hour will start evicting files from cache that haven't been accessed for 1 hour. When a cached file is accessed the 1 hour timer is reset to 0 and will wait for 1 more hour before evicting. Specify the time with standard notation, s, m, h, d, w .

You should not run two copies of rclone using the same VFS cache with the same or overlapping remotes if using --vfs-cache-mode > off. This can potentially cause data corruption if you do. You can work around this by giving each rclone its own cache hierarchy with --cache-dir. You don't need to worry about this if the remotes in use don't overlap.

--vfs-cache-mode off

In this mode (the default) the cache will read directly from the remote and write directly to the remote without caching anything on disk.

This will mean some operations are not possible

--vfs-cache-mode minimal

This is very similar to "off" except that files opened for read AND write will be buffered to disk. This means that files opened for write will be a lot more compatible, but uses the minimal disk space.

These operations are not possible

--vfs-cache-mode writes

In this mode files opened for read only are still read directly from the remote, write only and read/write files are buffered to disk first.

This mode should support all normal file system operations.

If an upload fails it will be retried at exponentially increasing intervals up to 1 minute.

--vfs-cache-mode full

In this mode all reads and writes are buffered to and from disk. When data is read from the remote this is buffered to disk as well.

In this mode the files in the cache will be sparse files and rclone will keep track of which bits of the files it has downloaded.

So if an application only reads the starts of each file, then rclone will only buffer the start of the file. These files will appear to be their full size in the cache, but they will be sparse files with only the data that has been downloaded present in them.

This mode should support all normal file system operations and is otherwise identical to --vfs-cache-mode writes.

When reading a file rclone will read --buffer-size plus --vfs-read-ahead bytes ahead. The --buffer-size is buffered in memory whereas the --vfs-read-ahead is buffered on disk.

When using this mode it is recommended that --buffer-size is not set too large and --vfs-read-ahead is set large if required.

IMPORTANT not all file systems support sparse files. In particular FAT/exFAT do not. Rclone will perform very badly if the cache directory is on a filesystem which doesn't support sparse files and it will log an ERROR message if one is detected.

Fingerprinting

Various parts of the VFS use fingerprinting to see if a local file copy has changed relative to a remote file. Fingerprints are made from:

where available on an object.

On some backends some of these attributes are slow to read (they take an extra API call per object, or extra work per object).

For example hash is slow with the local and sftp backends as they have to read the entire file and hash it, and modtime is slow with the s3, swift, ftp and qinqstor backends because they need to do an extra API call to fetch it.

If you use the --vfs-fast-fingerprint flag then rclone will not include the slow operations in the fingerprint. This makes the fingerprinting less accurate but much faster and will improve the opening time of cached files.

If you are running a vfs cache over local, s3 or swift backends then using this flag is recommended.

Note that if you change the value of this flag, the fingerprints of the files in the cache may be invalidated and the files will need to be downloaded again.

VFS Chunked Reading

When rclone reads files from a remote it reads them in chunks. This means that rather than requesting the whole file rclone reads the chunk specified. This can reduce the used download quota for some remotes by requesting only chunks from the remote that are actually read, at the cost of an increased number of requests.

These flags control the chunking:

--vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
--vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)

Rclone will start reading a chunk of size --vfs-read-chunk-size, and then double the size for each read. When --vfs-read-chunk-size-limit is specified, and greater than --vfs-read-chunk-size, the chunk size for each open file will get doubled only until the specified value is reached. If the value is "off", which is the default, the limit is disabled and the chunk size will grow indefinitely.

With --vfs-read-chunk-size 100M and --vfs-read-chunk-size-limit 0 the following parts will be downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When --vfs-read-chunk-size-limit 500M is specified, the result would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so on.

Setting --vfs-read-chunk-size to 0 or "off" disables chunked reading.

VFS Performance

These flags may be used to enable/disable features of the VFS for performance or other reasons. See also the chunked reading feature.

In particular S3 and Swift benefit hugely from the --no-modtime flag (or use --use-server-modtime for a slightly different effect) as each read of the modification time takes a transaction.

--no-checksum     Don't compare checksums on up/download.
--no-modtime      Don't read/write the modification time (can speed things up).
--no-seek         Don't allow seeking in files.
--read-only       Only allow read-only access.

Sometimes rclone is delivered reads or writes out of order. Rather than seeking rclone will wait a short time for the in sequence read or write to come in. These flags only come into effect when not using an on disk cache file.

--vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
--vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)

When using VFS write caching (--vfs-cache-mode with value writes or full), the global flag --transfers can be set to adjust the number of parallel uploads of modified files from the cache (the related global flag --checkers has no effect on the VFS).

--transfers int  Number of file transfers to run in parallel (default 4)

VFS Case Sensitivity

Linux file systems are case-sensitive: two files can differ only by case, and the exact case must be used when opening a file.

File systems in modern Windows are case-insensitive but case-preserving: although existing files can be opened using any case, the exact case used to create the file is preserved and available for programs to query. It is not allowed for two files in the same directory to differ only by case.

Usually file systems on macOS are case-insensitive. It is possible to make macOS file systems case-sensitive but that is not the default.

The --vfs-case-insensitive VFS flag controls how rclone handles these two cases. If its value is "false", rclone passes file names to the remote as-is. If the flag is "true" (or appears without a value on the command line), rclone may perform a "fixup" as explained below.

The user may specify a file name to open/delete/rename/etc with a case different than what is stored on the remote. If an argument refers to an existing file with exactly the same name, then the case of the existing file on the disk will be used. However, if a file name with exactly the same name is not found but a name differing only by case exists, rclone will transparently fixup the name. This fixup happens only when an existing file is requested. Case sensitivity of file names created anew by rclone is controlled by the underlying remote.

Note that case sensitivity of the operating system running rclone (the target) may differ from case sensitivity of a file system presented by rclone (the source). The flag controls whether "fixup" is performed to satisfy the target.

If the flag is not provided on the command line, then its default value depends on the operating system where rclone runs: "true" on Windows and macOS, "false" otherwise. If the flag is provided without a value, then it is "true".

VFS Disk Options

This flag allows you to manually set the statistics about the filing system. It can be useful when those statistics cannot be read correctly automatically.

--vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)

Alternate report of used bytes

Some backends, most notably S3, do not report the amount of bytes used. If you need this information to be available when running df on the filesystem, then pass the flag --vfs-used-is-size to rclone. With this flag set, instead of relying on the backend to report this information, rclone will scan the whole remote similar to rclone size and compute the total used space itself.

WARNING. Contrary to rclone size, this flag ignores filters so that the result is accurate. However, this is very inefficient and may cost lots of API calls resulting in extra charges. Use it as a last resort and only with caching.

Auth Proxy

If you supply the parameter --auth-proxy /path/to/program then rclone will use that program to generate backends on the fly which then are used to authenticate incoming requests. This uses a simple JSON based protocol with input on STDIN and output on STDOUT.

PLEASE NOTE: --auth-proxy and --authorized-keys cannot be used together, if --auth-proxy is set the authorized keys option will be ignored.

There is an example program bin/test_proxy.py in the rclone source code.

The program's job is to take a user and pass on the input and turn those into the config for a backend on STDOUT in JSON format. This config will have any default parameters for the backend added, but it won't use configuration from environment variables or command line options - it is the job of the proxy program to make a complete config.

This config generated must have this extra parameter - _root - root to use for the backend

And it may have this parameter - _obscure - comma separated strings for parameters to obscure

If password authentication was used by the client, input to the proxy process (on STDIN) would look similar to this:

{
    "user": "me",
    "pass": "mypassword"
}

If public-key authentication was used by the client, input to the proxy process (on STDIN) would look similar to this:

{
    "user": "me",
    "public_key": "AAAAB3NzaC1yc2EAAAADAQABAAABAQDuwESFdAe14hVS6omeyX7edc...JQdf"
}

And as an example return this on STDOUT

{
    "type": "sftp",
    "_root": "",
    "_obscure": "pass",
    "user": "me",
    "pass": "mypassword",
    "host": "sftp.example.com"
}

This would mean that an SFTP backend would be created on the fly for the user and pass/public_key returned in the output to the host given. Note that since _obscure is set to pass, rclone will obscure the pass parameter before creating the backend (which is required for sftp backends).

The program can manipulate the supplied user in any way, for example to make proxy to many different sftp backends, you could make the user be user@example.com and then set the host to example.com in the output and the user to user. For security you'd probably want to restrict the host to a limited list.

Note that an internal cache is keyed on user so only use that for configuration, don't use pass or public_key. This also means that if a user's password or public-key is changed the cache will need to expire (which takes 5 mins) before it takes effect.

This can be used to build general purpose proxies to any kind of backend that rclone supports.

rclone serve webdav

Serve remote:path over WebDAV.

Synopsis

Run a basic WebDAV server to serve a remote over HTTP via the WebDAV protocol. This can be viewed with a WebDAV client, through a web browser, or you can make a remote of type WebDAV to read and write it.

WebDAV options

--etag-hash

This controls the ETag header. Without this flag the ETag will be based on the ModTime and Size of the object.

If this flag is set to "auto" then rclone will choose the first supported hash on the backend or you can use a named hash such as "MD5" or "SHA-1". Use the hashsum command to see the full list.

Access WebDAV on Windows

WebDAV shared folder can be mapped as a drive on Windows, however the default settings prevent it. Windows will fail to connect to the server using insecure Basic authentication. It will not even display any login dialog. Windows requires SSL / HTTPS connection to be used with Basic. If you try to connect via Add Network Location Wizard you will get the following error: "The folder you entered does not appear to be valid. Please choose another". However, you still can connect if you set the following registry key on a client machine: HKEY_LOCAL_MACHINEto 2. The BasicAuthLevel can be set to the following values: 0 - Basic authentication disabled 1 - Basic authentication enabled for SSL connections only 2 - Basic authentication enabled for SSL connections and for non-SSL connections If required, increase the FileSizeLimitInBytes to a higher value. Navigate to the Services interface, then restart the WebClient service.

Access Office applications on WebDAV

Navigate to following registry HKEY_CURRENT_USER[14.0/15.0/16.0] Create a new DWORD BasicAuthLevel with value 2. 0 - Basic authentication disabled 1 - Basic authentication enabled for SSL connections only 2 - Basic authentication enabled for SSL and for non-SSL connections

Server options

Use --addr to specify which IP address and port the server should listen on, eg --addr 1.2.3.4:8000 or --addr :8080 to listen to all IPs. By default it only listens on localhost. You can use port :0 to let the OS choose an available port.

If you set --addr to listen on a public or LAN accessible IP address then using Authentication is advised - see the next section for info.

You can use a unix socket by setting the url to unix:///path/to/socket or just by using an absolute path name. Note that unix sockets bypass the authentication - this is expected to be done with file system permissions.

--addr may be repeated to listen on multiple IPs/ports/sockets.

--server-read-timeout and --server-write-timeout can be used to control the timeouts on the server. Note that this is the total time for a transfer.

--max-header-bytes controls the maximum number of bytes the server will accept in the HTTP header.

--baseurl controls the URL prefix that rclone serves from. By default rclone will serve from the root. If you used --baseurl "/rclone" then rclone would serve from a URL starting with "/rclone/". This is useful if you wish to proxy rclone serve. Rclone automatically inserts leading and trailing "/" on --baseurl, so --baseurl "rclone", --baseurl "/rclone" and --baseurl "/rclone/" are all treated identically.

TLS (SSL)

By default this will serve over http. If you want you can serve over https. You will need to supply the --cert and --key flags. If you wish to do client side certificate validation then you will need to supply --client-ca also.

--cert should be a either a PEM encoded certificate or a concatenation of that with the CA certificate. --key should be the PEM encoded private key and --client-ca should be the PEM encoded client certificate authority certificate.

--min-tls-version is minimum TLS version that is acceptable. Valid values are "tls1.0", "tls1.1", "tls1.2" and "tls1.3" (default "tls1.0").

Template

--template allows a user to specify a custom markup template for HTTP and WebDAV serve functions. The server exports the following markup to be used within the template to server pages:

Parameter Description
.Name The full path of a file/directory.
.Title Directory listing of .Name
.Sort The current sort used. This is changeable via ?sort= parameter
Sort Options: namedirfirst,name,size,time (default namedirfirst)
.Order The current ordering used. This is changeable via ?order= parameter
Order Options: asc,desc (default asc)
.Query Currently unused.
.Breadcrumb Allows for creating a relative navigation
-- .Link The relative to the root link of the Text.
-- .Text The Name of the directory.
.Entries Information about a specific file/directory.
-- .URL The 'url' of an entry.
-- .Leaf Currently same as 'URL' but intended to be 'just' the name.
-- .IsDir Boolean for if an entry is a directory or not.
-- .Size Size in Bytes of the entry.
-- .ModTime The UTC timestamp of an entry.

Authentication

By default this will serve files without needing a login.

You can either use an htpasswd file which can take lots of users, or set a single username and password with the --user and --pass flags.

If no static users are configured by either of the above methods, and client certificates are required by the --client-ca flag passed to the server, the client certificate common name will be considered as the username.

Use --htpasswd /path/to/htpasswd to provide an htpasswd file. This is in standard apache format and supports MD5, SHA1 and BCrypt for basic authentication. Bcrypt is recommended.

To create an htpasswd file:

touch htpasswd
htpasswd -B htpasswd user
htpasswd -B htpasswd anotherUser

The password file can be updated while rclone is running.

Use --realm to set the authentication realm.

Use --salt to change the password hashing salt from the default.

VFS - Virtual File System

This command uses the VFS layer. This adapts the cloud storage objects that rclone uses into something which looks much more like a disk filing system.

Cloud storage objects have lots of properties which aren't like disk files - you can't extend them or write to the middle of them, so the VFS layer has to deal with that. Because there is no one right way of doing this there are various options explained below.

The VFS layer also implements a directory cache - this caches info about files and directories (but not the data) in memory.

VFS Directory Cache

Using the --dir-cache-time flag, you can control how long a directory should be considered up to date and not refreshed from the backend. Changes made through the VFS will appear immediately or invalidate the cache.

--dir-cache-time duration   Time to cache directory entries for (default 5m0s)
--poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)

However, changes made directly on the cloud storage by the web interface or a different copy of rclone will only be picked up once the directory cache expires if the backend configured does not support polling for changes. If the backend supports polling, changes will be picked up within the polling interval.

You can send a SIGHUP signal to rclone for it to flush all directory caches, regardless of how old they are. Assuming only one rclone instance is running, you can reset the cache like this:

kill -SIGHUP $(pidof rclone)

If you configure rclone with a remote control then you can use rclone rc to flush the whole directory cache:

rclone rc vfs/forget

Or individual files or directories:

rclone rc vfs/forget file=path/to/file dir=path/to/dir

VFS File Buffering

The --buffer-size flag determines the amount of memory, that will be used to buffer data in advance.

Each open file will try to keep the specified amount of data in memory at all times. The buffered data is bound to one open file and won't be shared.

This flag is a upper limit for the used memory per open file. The buffer will only use memory for data that is downloaded but not not yet read. If the buffer is empty, only a small amount of memory will be used.

The maximum memory used by rclone for buffering can be up to --buffer-size * open files.

VFS File Caching

These flags control the VFS file caching options. File caching is necessary to make the VFS layer appear compatible with a normal file system. It can be disabled at the cost of some compatibility.

For example you'll need to enable VFS caching if you want to read and write simultaneously to a file. See below for more details.

Note that the VFS cache is separate from the cache backend and you may find that you need one or the other or both.

--cache-dir string                     Directory rclone will use for caching.
--vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
--vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
--vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
--vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
--vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
--vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)

If run with -vv rclone will print the location of the file cache. The files are stored in the user cache file area which is OS dependent but can be controlled with --cache-dir or setting the appropriate environment variable.

The cache has 4 different modes selected by --vfs-cache-mode. The higher the cache mode the more compatible rclone becomes at the cost of using disk space.

Note that files are written back to the remote only when they are closed and if they haven't been accessed for --vfs-write-back seconds. If rclone is quit or dies with files that haven't been uploaded, these will be uploaded next time rclone is run with the same flags.

If using --vfs-cache-max-size or --vfs-cache-min-free-size note that the cache may exceed these quotas for two reasons. Firstly because it is only checked every --vfs-cache-poll-interval. Secondly because open files cannot be evicted from the cache. When --vfs-cache-max-size or --vfs-cache-min-free-size is exceeded, rclone will attempt to evict the least accessed files from the cache first. rclone will start with files that haven't been accessed for the longest. This cache flushing strategy is efficient and more relevant files are likely to remain cached.

The --vfs-cache-max-age will evict files from the cache after the set time since last access has passed. The default value of 1 hour will start evicting files from cache that haven't been accessed for 1 hour. When a cached file is accessed the 1 hour timer is reset to 0 and will wait for 1 more hour before evicting. Specify the time with standard notation, s, m, h, d, w .

You should not run two copies of rclone using the same VFS cache with the same or overlapping remotes if using --vfs-cache-mode > off. This can potentially cause data corruption if you do. You can work around this by giving each rclone its own cache hierarchy with --cache-dir. You don't need to worry about this if the remotes in use don't overlap.

--vfs-cache-mode off

In this mode (the default) the cache will read directly from the remote and write directly to the remote without caching anything on disk.

This will mean some operations are not possible

--vfs-cache-mode minimal

This is very similar to "off" except that files opened for read AND write will be buffered to disk. This means that files opened for write will be a lot more compatible, but uses the minimal disk space.

These operations are not possible

--vfs-cache-mode writes

In this mode files opened for read only are still read directly from the remote, write only and read/write files are buffered to disk first.

This mode should support all normal file system operations.

If an upload fails it will be retried at exponentially increasing intervals up to 1 minute.

--vfs-cache-mode full

In this mode all reads and writes are buffered to and from disk. When data is read from the remote this is buffered to disk as well.

In this mode the files in the cache will be sparse files and rclone will keep track of which bits of the files it has downloaded.

So if an application only reads the starts of each file, then rclone will only buffer the start of the file. These files will appear to be their full size in the cache, but they will be sparse files with only the data that has been downloaded present in them.

This mode should support all normal file system operations and is otherwise identical to --vfs-cache-mode writes.

When reading a file rclone will read --buffer-size plus --vfs-read-ahead bytes ahead. The --buffer-size is buffered in memory whereas the --vfs-read-ahead is buffered on disk.

When using this mode it is recommended that --buffer-size is not set too large and --vfs-read-ahead is set large if required.

IMPORTANT not all file systems support sparse files. In particular FAT/exFAT do not. Rclone will perform very badly if the cache directory is on a filesystem which doesn't support sparse files and it will log an ERROR message if one is detected.

Fingerprinting

Various parts of the VFS use fingerprinting to see if a local file copy has changed relative to a remote file. Fingerprints are made from:

where available on an object.

On some backends some of these attributes are slow to read (they take an extra API call per object, or extra work per object).

For example hash is slow with the local and sftp backends as they have to read the entire file and hash it, and modtime is slow with the s3, swift, ftp and qinqstor backends because they need to do an extra API call to fetch it.

If you use the --vfs-fast-fingerprint flag then rclone will not include the slow operations in the fingerprint. This makes the fingerprinting less accurate but much faster and will improve the opening time of cached files.

If you are running a vfs cache over local, s3 or swift backends then using this flag is recommended.

Note that if you change the value of this flag, the fingerprints of the files in the cache may be invalidated and the files will need to be downloaded again.

VFS Chunked Reading

When rclone reads files from a remote it reads them in chunks. This means that rather than requesting the whole file rclone reads the chunk specified. This can reduce the used download quota for some remotes by requesting only chunks from the remote that are actually read, at the cost of an increased number of requests.

These flags control the chunking:

--vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
--vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)

Rclone will start reading a chunk of size --vfs-read-chunk-size, and then double the size for each read. When --vfs-read-chunk-size-limit is specified, and greater than --vfs-read-chunk-size, the chunk size for each open file will get doubled only until the specified value is reached. If the value is "off", which is the default, the limit is disabled and the chunk size will grow indefinitely.

With --vfs-read-chunk-size 100M and --vfs-read-chunk-size-limit 0 the following parts will be downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When --vfs-read-chunk-size-limit 500M is specified, the result would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so on.

Setting --vfs-read-chunk-size to 0 or "off" disables chunked reading.

VFS Performance

These flags may be used to enable/disable features of the VFS for performance or other reasons. See also the chunked reading feature.

In particular S3 and Swift benefit hugely from the --no-modtime flag (or use --use-server-modtime for a slightly different effect) as each read of the modification time takes a transaction.

--no-checksum     Don't compare checksums on up/download.
--no-modtime      Don't read/write the modification time (can speed things up).
--no-seek         Don't allow seeking in files.
--read-only       Only allow read-only access.

Sometimes rclone is delivered reads or writes out of order. Rather than seeking rclone will wait a short time for the in sequence read or write to come in. These flags only come into effect when not using an on disk cache file.

--vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
--vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)

When using VFS write caching (--vfs-cache-mode with value writes or full), the global flag --transfers can be set to adjust the number of parallel uploads of modified files from the cache (the related global flag --checkers has no effect on the VFS).

--transfers int  Number of file transfers to run in parallel (default 4)

VFS Case Sensitivity

Linux file systems are case-sensitive: two files can differ only by case, and the exact case must be used when opening a file.

File systems in modern Windows are case-insensitive but case-preserving: although existing files can be opened using any case, the exact case used to create the file is preserved and available for programs to query. It is not allowed for two files in the same directory to differ only by case.

Usually file systems on macOS are case-insensitive. It is possible to make macOS file systems case-sensitive but that is not the default.

The --vfs-case-insensitive VFS flag controls how rclone handles these two cases. If its value is "false", rclone passes file names to the remote as-is. If the flag is "true" (or appears without a value on the command line), rclone may perform a "fixup" as explained below.

The user may specify a file name to open/delete/rename/etc with a case different than what is stored on the remote. If an argument refers to an existing file with exactly the same name, then the case of the existing file on the disk will be used. However, if a file name with exactly the same name is not found but a name differing only by case exists, rclone will transparently fixup the name. This fixup happens only when an existing file is requested. Case sensitivity of file names created anew by rclone is controlled by the underlying remote.

Note that case sensitivity of the operating system running rclone (the target) may differ from case sensitivity of a file system presented by rclone (the source). The flag controls whether "fixup" is performed to satisfy the target.

If the flag is not provided on the command line, then its default value depends on the operating system where rclone runs: "true" on Windows and macOS, "false" otherwise. If the flag is provided without a value, then it is "true".

VFS Disk Options

This flag allows you to manually set the statistics about the filing system. It can be useful when those statistics cannot be read correctly automatically.

--vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)

Alternate report of used bytes

Some backends, most notably S3, do not report the amount of bytes used. If you need this information to be available when running df on the filesystem, then pass the flag --vfs-used-is-size to rclone. With this flag set, instead of relying on the backend to report this information, rclone will scan the whole remote similar to rclone size and compute the total used space itself.

WARNING. Contrary to rclone size, this flag ignores filters so that the result is accurate. However, this is very inefficient and may cost lots of API calls resulting in extra charges. Use it as a last resort and only with caching.

Auth Proxy

If you supply the parameter --auth-proxy /path/to/program then rclone will use that program to generate backends on the fly which then are used to authenticate incoming requests. This uses a simple JSON based protocol with input on STDIN and output on STDOUT.

PLEASE NOTE: --auth-proxy and --authorized-keys cannot be used together, if --auth-proxy is set the authorized keys option will be ignored.

There is an example program bin/test_proxy.py in the rclone source code.

The program's job is to take a user and pass on the input and turn those into the config for a backend on STDOUT in JSON format. This config will have any default parameters for the backend added, but it won't use configuration from environment variables or command line options - it is the job of the proxy program to make a complete config.

This config generated must have this extra parameter - _root - root to use for the backend

And it may have this parameter - _obscure - comma separated strings for parameters to obscure

If password authentication was used by the client, input to the proxy process (on STDIN) would look similar to this:

{
    "user": "me",
    "pass": "mypassword"
}

If public-key authentication was used by the client, input to the proxy process (on STDIN) would look similar to this:

{
    "user": "me",
    "public_key": "AAAAB3NzaC1yc2EAAAADAQABAAABAQDuwESFdAe14hVS6omeyX7edc...JQdf"
}

And as an example return this on STDOUT

{
    "type": "sftp",
    "_root": "",
    "_obscure": "pass",
    "user": "me",
    "pass": "mypassword",
    "host": "sftp.example.com"
}

This would mean that an SFTP backend would be created on the fly for the user and pass/public_key returned in the output to the host given. Note that since _obscure is set to pass, rclone will obscure the pass parameter before creating the backend (which is required for sftp backends).

The program can manipulate the supplied user in any way, for example to make proxy to many different sftp backends, you could make the user be user@example.com and then set the host to example.com in the output and the user to user. For security you'd probably want to restrict the host to a limited list.

Note that an internal cache is keyed on user so only use that for configuration, don't use pass or public_key. This also means that if a user's password or public-key is changed the cache will need to expire (which takes 5 mins) before it takes effect.

This can be used to build general purpose proxies to any kind of backend that rclone supports.

rclone settier

Changes storage class/tier of objects in remote.

Synopsis

rclone settier changes storage tier or class at remote if supported. Few cloud storage services provides different storage classes on objects, for example AWS S3 and Glacier, Azure Blob storage - Hot, Cool and Archive, Google Cloud Storage, Regional Storage, Nearline, Coldline etc.

Note that, certain tier changes make objects not available to access immediately. For example tiering to archive in azure blob storage makes objects in frozen state, user can restore by setting tier to Hot/Cool, similarly S3 to Glacier makes object inaccessible.true

You can use it to tier single object

rclone settier Cool remote:path/file

Or use rclone filters to set tier on only specific files

rclone --include "*.txt" settier Hot remote:path/dir

Or just provide remote directory and all files in directory will be tiered

rclone tree

List the contents of the remote in a tree like fashion.

Synopsis

rclone tree lists the contents of a remote in a similar way to the unix tree command.

For example

$ rclone tree remote:path
/
├── file1
├── file2
├── file3
└── subdir
    ├── file4
    └── file5

1 directories, 5 files

You can use any of the filtering options with the tree command (e.g. --include and --exclude. You can also use --fast-list.

The tree command has many options for controlling the listing which are compatible with the tree command, for example you can include file sizes with --size. Note that not all of them have short options as they conflict with rclone's short options.

For a more interactive navigation of the remote see the ncdu command.

SEE ALSO

Copying single files

rclone normally syncs or copies directories. However, if the source remote points to a file, rclone will just copy that file. The destination remote must point to a directory - rclone will give the error Failed to create file system for "remote:file": is a file not a directory if it isn't.

For example, suppose you have a remote with a file in called test.jpg, then you could copy just that file like this

rclone copy remote:test.jpg /tmp/download

The file test.jpg will be placed inside /tmp/download.

This is equivalent to specifying

rclone copy --files-from /tmp/files remote: /tmp/download

Where /tmp/files contains the single line

test.jpg

It is recommended to use copy when copying individual files, not sync. They have pretty much the same effect but copy will use a lot less memory.

Syntax of remote paths

The syntax of the paths passed to the rclone command are as follows.

/path/to/dir

This refers to the local file system.

On Windows \ may be used instead of / in local paths only, non local paths must use /. See local filesystem documentation for more about Windows-specific paths.

These paths needn't start with a leading / - if they don't then they will be relative to the current directory.

remote:path/to/dir

This refers to a directory path/to/dir on remote: as defined in the config file (configured with rclone config).

remote:/path/to/dir

On most backends this is refers to the same directory as remote:path/to/dir and that format should be preferred. On a very small number of remotes (FTP, SFTP, Dropbox for business) this will refer to a different directory. On these, paths without a leading / will refer to your "home" directory and paths with a leading / will refer to the root.

:backend:path/to/dir

This is an advanced form for creating remotes on the fly. backend should be the name or prefix of a backend (the type in the config file) and all the configuration for the backend should be provided on the command line (or in environment variables).

Here are some examples:

rclone lsd --http-url https://pub.rclone.org :http:

To list all the directories in the root of https://pub.rclone.org/.

rclone lsf --http-url https://example.com :http:path/to/dir

To list files and directories in https://example.com/path/to/dir/

rclone copy --http-url https://example.com :http:path/to/dir /tmp/dir

To copy files and directories in https://example.com/path/to/dir to /tmp/dir.

rclone copy --sftp-host example.com :sftp:path/to/dir /tmp/dir

To copy files and directories from example.com in the relative directory path/to/dir to /tmp/dir using sftp.

Connection strings

The above examples can also be written using a connection string syntax, so instead of providing the arguments as command line parameters --http-url https://pub.rclone.org they are provided as part of the remote specification as a kind of connection string.

rclone lsd ":http,url='https://pub.rclone.org':"
rclone lsf ":http,url='https://example.com':path/to/dir"
rclone copy ":http,url='https://example.com':path/to/dir" /tmp/dir
rclone copy :sftp,host=example.com:path/to/dir /tmp/dir

These can apply to modify existing remotes as well as create new remotes with the on the fly syntax. This example is equivalent to adding the --drive-shared-with-me parameter to the remote gdrive:.

rclone lsf "gdrive,shared_with_me:path/to/dir"

The major advantage to using the connection string style syntax is that it only applies to the remote, not to all the remotes of that type of the command line. A common confusion is this attempt to copy a file shared on google drive to the normal drive which does not work because the --drive-shared-with-me flag applies to both the source and the destination.

rclone copy --drive-shared-with-me gdrive:shared-file.txt gdrive:

However using the connection string syntax, this does work.

rclone copy "gdrive,shared_with_me:shared-file.txt" gdrive:

Note that the connection string only affects the options of the immediate backend. If for example gdriveCrypt is a crypt based on gdrive, then the following command will not work as intended, because shared_with_me is ignored by the crypt backend:

rclone copy "gdriveCrypt,shared_with_me:shared-file.txt" gdriveCrypt:

The connection strings have the following syntax

remote,parameter=value,parameter2=value2:path/to/dir
:backend,parameter=value,parameter2=value2:path/to/dir

If the parameter has a : or , then it must be placed in quotes " or ', so

remote,parameter="colon:value",parameter2="comma,value":path/to/dir
:backend,parameter='colon:value',parameter2='comma,value':path/to/dir

If a quoted value needs to include that quote, then it should be doubled, so

remote,parameter="with""quote",parameter2='with''quote':path/to/dir

This will make parameter be with"quote and parameter2 be with'quote.

If you leave off the =parameter then rclone will substitute =true which works very well with flags. For example, to use s3 configured in the environment you could use:

rclone lsd :s3,env_auth:

Which is equivalent to

rclone lsd :s3,env_auth=true:

Note that on the command line you might need to surround these connection strings with " or ' to stop the shell interpreting any special characters within them.

If you are a shell master then you'll know which strings are OK and which aren't, but if you aren't sure then enclose them in " and use ' as the inside quote. This syntax works on all OSes.

rclone copy ":http,url='https://example.com':path/to/dir" /tmp/dir

On Linux/macOS some characters are still interpreted inside " strings in the shell (notably \ and $ and ") so if your strings contain those you can swap the roles of " and ' thus. (This syntax does not work on Windows.)

rclone copy ':http,url="https://example.com":path/to/dir' /tmp/dir

Connection strings, config and logging

If you supply extra configuration to a backend by command line flag, environment variable or connection string then rclone will add a suffix based on the hash of the config to the name of the remote, eg

rclone -vv lsf --s3-chunk-size 20M s3:

Has the log message

DEBUG : s3: detected overridden config - adding "{Srj1p}" suffix to name

This is so rclone can tell the modified remote apart from the unmodified remote when caching the backends.

This should only be noticeable in the logs.

This means that on the fly backends such as

rclone -vv lsf :s3,env_auth:

Will get their own names

DEBUG : :s3: detected overridden config - adding "{YTu53}" suffix to name

Valid remote names

Remote names are case sensitive, and must adhere to the following rules: - May contain number, letter, _, -, ., +, @ and space. - May not start with - or space. - May not end with space.

Starting with rclone version 1.61, any Unicode numbers and letters are allowed, while in older versions it was limited to plain ASCII (0-9, A-Z, a-z). If you use the same rclone configuration from different shells, which may be configured with different character encoding, you must be cautious to use characters that are possible to write in all of them. This is mostly a problem on Windows, where the console traditionally uses a non-Unicode character set - defined by the so-called "code page".

Do not use single character names on Windows as it creates ambiguity with Windows drives' names, e.g.: remote called C is indistinguishable from C drive. Rclone will always assume that single letter name refers to a drive.

Quoting and the shell

When you are typing commands to your computer you are using something called the command line shell. This interprets various characters in an OS specific way.

Here are some gotchas which may help users unfamiliar with the shell rules

Linux / OSX

If your names have spaces or shell metacharacters (e.g. *, ?, $, ', ", etc.) then you must quote them. Use single quotes ' by default.

rclone copy 'Important files?' remote:backup

If you want to send a ' you will need to use ", e.g.

rclone copy "O'Reilly Reviews" remote:backup

The rules for quoting metacharacters are complicated and if you want the full details you'll have to consult the manual page for your shell.

Windows

If your names have spaces in you need to put them in ", e.g.

rclone copy "E:\folder name\folder name\folder name" remote:backup

If you are using the root directory on its own then don't quote it (see #464 for why), e.g.

rclone copy E:\ remote:backup

Copying files or directories with : in the names

rclone uses : to mark a remote name. This is, however, a valid filename component in non-Windows OSes. The remote name parser will only search for a : up to the first / so if you need to act on a file or directory like this then use the full path starting with a /, or use ./ as a current directory prefix.

So to sync a directory called sync:me to a remote called remote: use

rclone sync --interactive ./sync:me remote:path

or

rclone sync --interactive /full/path/to/sync:me remote:path

Server Side Copy

Most remotes (but not all - see the overview) support server-side copy.

This means if you want to copy one folder to another then rclone won't download all the files and re-upload them; it will instruct the server to copy them in place.

Eg

rclone copy s3:oldbucket s3:newbucket

Will copy the contents of oldbucket to newbucket without downloading and re-uploading.

Remotes which don't support server-side copy will download and re-upload in this case.

Server side copies are used with sync and copy and will be identified in the log when using the -v flag. The move command may also use them if remote doesn't support server-side move directly. This is done by issuing a server-side copy then a delete which is much quicker than a download and re-upload.

Server side copies will only be attempted if the remote names are the same.

This can be used when scripting to make aged backups efficiently, e.g.

rclone sync --interactive remote:current-backup remote:previous-backup
rclone sync --interactive /path/to/files remote:current-backup

Metadata support

Metadata is data about a file which isn't the contents of the file. Normally rclone only preserves the modification time and the content (MIME) type where possible.

Rclone supports preserving all the available metadata on files (not directories) when using the --metadata or -M flag.

Exactly what metadata is supported and what that support means depends on the backend. Backends that support metadata have a metadata section in their docs and are listed in the features table (Eg local, s3)

Rclone only supports a one-time sync of metadata. This means that metadata will be synced from the source object to the destination object only when the source object has changed and needs to be re-uploaded. If the metadata subsequently changes on the source object without changing the object itself then it won't be synced to the destination object. This is in line with the way rclone syncs Content-Type without the --metadata flag.

Using --metadata when syncing from local to local will preserve file attributes such as file mode, owner, extended attributes (not Windows).

Note that arbitrary metadata may be added to objects using the --metadata-set key=value flag when the object is first uploaded. This flag can be repeated as many times as necessary.

Types of metadata

Metadata is divided into two type. System metadata and User metadata.

Metadata which the backend uses itself is called system metadata. For example on the local backend the system metadata uid will store the user ID of the file when used on a unix based platform.

Arbitrary metadata is called user metadata and this can be set however is desired.

When objects are copied from backend to backend, they will attempt to interpret system metadata if it is supplied. Metadata may change from being user metadata to system metadata as objects are copied between different backends. For example copying an object from s3 sets the content-type metadata. In a backend which understands this (like azureblob) this will become the Content-Type of the object. In a backend which doesn't understand this (like the local backend) this will become user metadata. However should the local object be copied back to s3, the Content-Type will be set correctly.

Metadata framework

Rclone implements a metadata framework which can read metadata from an object and write it to the object when (and only when) it is being uploaded.

This metadata is stored as a dictionary with string keys and string values.

There are some limits on the names of the keys (these may be clarified further in the future).

Each backend can provide system metadata that it understands. Some backends can also store arbitrary user metadata.

Where possible the key names are standardized, so, for example, it is possible to copy object metadata from s3 to azureblob for example and metadata will be translated appropriately.

Some backends have limits on the size of the metadata and rclone will give errors on upload if they are exceeded.

Metadata preservation

The goal of the implementation is to

  1. Preserve metadata if at all possible
  2. Interpret metadata if at all possible

The consequences of 1 is that you can copy an S3 object to a local disk then back to S3 losslessly. Likewise you can copy a local file with file attributes and xattrs from local disk to s3 and back again losslessly.

The consequence of 2 is that you can copy an S3 object with metadata to Azureblob (say) and have the metadata appear on the Azureblob object also.

Standard system metadata

Here is a table of standard system metadata which, if appropriate, a backend may implement.

key description example
mode File type and mode: octal, unix style 0100664
uid User ID of owner: decimal number 500
gid Group ID of owner: decimal number 500
rdev Device ID (if special file) => hexadecimal 0
atime Time of last access: RFC 3339 2006-01-02T15:04:05.999999999Z07:00
mtime Time of last modification: RFC 3339 2006-01-02T15:04:05.999999999Z07:00
btime Time of file creation (birth): RFC 3339 2006-01-02T15:04:05.999999999Z07:00
cache-control Cache-Control header no-cache
content-disposition Content-Disposition header inline
content-encoding Content-Encoding header gzip
content-language Content-Language header en-US
content-type Content-Type header text/plain

The metadata keys mtime and content-type will take precedence if supplied in the metadata over reading the Content-Type or modification time of the source object.

Hashes are not included in system metadata as there is a well defined way of reading those already.

Options

Rclone has a number of options to control its behaviour.

Options that take parameters can have the values passed in two ways, --option=value or --option value. However boolean (true/false) options behave slightly differently to the other options in that --boolean sets the option to true and the absence of the flag sets it to false. It is also possible to specify --boolean=false or --boolean=true. Note that --boolean false is not valid - this is parsed as --boolean and the false is parsed as an extra command line argument for rclone.

Time or duration options

TIME or DURATION options can be specified as a duration string or a time string.

A duration string is a possibly signed sequence of decimal numbers, each with optional fraction and a unit suffix, such as "300ms", "-1.5h" or "2h45m". Default units are seconds or the following abbreviations are valid:

These can also be specified as an absolute time in the following formats:

Size options

Options which use SIZE use KiB (multiples of 1024 bytes) by default. However, a suffix of B for Byte, K for KiB, M for MiB, G for GiB, T for TiB and P for PiB may be used. These are the binary units, e.g. 1, 2**10, 2**20, 2**30 respectively.

--backup-dir=DIR

When using sync, copy or move any files which would have been overwritten or deleted are moved in their original hierarchy into this directory.

If --suffix is set, then the moved files will have the suffix added to them. If there is a file with the same path (after the suffix has been added) in DIR, then it will be overwritten.

The remote in use must support server-side move or copy and you must use the same remote as the destination of the sync. The backup directory must not overlap the destination directory without it being excluded by a filter rule.

For example

rclone sync --interactive /path/to/local remote:current --backup-dir remote:old

will sync /path/to/local to remote:current, but for any files which would have been updated or deleted will be stored in remote:old.

If running rclone from a script you might want to use today's date as the directory name passed to --backup-dir to store the old files, or you might want to pass --suffix with today's date.

See --compare-dest and --copy-dest.

--bind string

Local address to bind to for outgoing connections. This can be an IPv4 address (1.2.3.4), an IPv6 address (1234::789A) or host name. If the host name doesn't resolve or resolves to more than one IP address it will give an error.

You can use --bind 0.0.0.0 to force rclone to use IPv4 addresses and --bind ::0 to force rclone to use IPv6 addresses.

--bwlimit=BANDWIDTH_SPEC

This option controls the bandwidth limit. For example

--bwlimit 10M

would mean limit the upload and download bandwidth to 10 MiB/s. NB this is bytes per second not bits per second. To use a single limit, specify the desired bandwidth in KiB/s, or use a suffix B|K|M|G|T|P. The default is 0 which means to not limit bandwidth.

The upload and download bandwidth can be specified separately, as --bwlimit UP:DOWN, so

--bwlimit 10M:100k

would mean limit the upload bandwidth to 10 MiB/s and the download bandwidth to 100 KiB/s. Either limit can be "off" meaning no limit, so to just limit the upload bandwidth you would use

--bwlimit 10M:off

this would limit the upload bandwidth to 10 MiB/s but the download bandwidth would be unlimited.

When specified as above the bandwidth limits last for the duration of run of the rclone binary.

It is also possible to specify a "timetable" of limits, which will cause certain limits to be applied at certain times. To specify a timetable, format your entries as WEEKDAY-HH:MM,BANDWIDTH WEEKDAY-HH:MM,BANDWIDTH... where: WEEKDAY is optional element.

An example of a typical timetable to avoid link saturation during daytime working hours could be:

--bwlimit "08:00,512k 12:00,10M 13:00,512k 18:00,30M 23:00,off"

In this example, the transfer bandwidth will be set to 512 KiB/s at 8am every day. At noon, it will rise to 10 MiB/s, and drop back to 512 KiB/sec at 1pm. At 6pm, the bandwidth limit will be set to 30 MiB/s, and at 11pm it will be completely disabled (full speed). Anything between 11pm and 8am will remain unlimited.

An example of timetable with WEEKDAY could be:

--bwlimit "Mon-00:00,512 Fri-23:59,10M Sat-10:00,1M Sun-20:00,off"

It means that, the transfer bandwidth will be set to 512 KiB/s on Monday. It will rise to 10 MiB/s before the end of Friday. At 10:00 on Saturday it will be set to 1 MiB/s. From 20:00 on Sunday it will be unlimited.

Timeslots without WEEKDAY are extended to the whole week. So this example:

--bwlimit "Mon-00:00,512 12:00,1M Sun-20:00,off"

Is equivalent to this:

--bwlimit "Mon-00:00,512Mon-12:00,1M Tue-12:00,1M Wed-12:00,1M Thu-12:00,1M Fri-12:00,1M Sat-12:00,1M Sun-12:00,1M Sun-20:00,off"

Bandwidth limit apply to the data transfer for all backends. For most backends the directory listing bandwidth is also included (exceptions being the non HTTP backends, ftp, sftp and storj).

Note that the units are Byte/s, not bit/s. Typically connections are measured in bit/s - to convert divide by 8. For example, let's say you have a 10 Mbit/s connection and you wish rclone to use half of it - 5 Mbit/s. This is 5/8 = 0.625 MiB/s so you would use a --bwlimit 0.625M parameter for rclone.

On Unix systems (Linux, macOS, …) the bandwidth limiter can be toggled by sending a SIGUSR2 signal to rclone. This allows to remove the limitations of a long running rclone transfer and to restore it back to the value specified with --bwlimit quickly when needed. Assuming there is only one rclone instance running, you can toggle the limiter like this:

kill -SIGUSR2 $(pidof rclone)

If you configure rclone with a remote control then you can use change the bwlimit dynamically:

rclone rc core/bwlimit rate=1M

--bwlimit-file=BANDWIDTH_SPEC

This option controls per file bandwidth limit. For the options see the --bwlimit flag.

For example use this to allow no transfers to be faster than 1 MiB/s

--bwlimit-file 1M

This can be used in conjunction with --bwlimit.

Note that if a schedule is provided the file will use the schedule in effect at the start of the transfer.

--buffer-size=SIZE

Use this sized buffer to speed up file transfers. Each --transfer will use this much memory for buffering.

When using mount or cmount each open file descriptor will use this much memory for buffering. See the mount documentation for more details.

Set to 0 to disable the buffering for the minimum memory usage.

Note that the memory allocation of the buffers is influenced by the --use-mmap flag.

--cache-dir=DIR

Specify the directory rclone will use for caching, to override the default.

Default value is depending on operating system: - Windows %LocalAppData%\rclone, if LocalAppData is defined. - macOS $HOME/Library/Caches/rclone if HOME is defined. - Unix $XDG_CACHE_HOME/rclone if XDG_CACHE_HOME is defined, else $HOME/.cache/rclone if HOME is defined. - Fallback (on all OS) to $TMPDIR/rclone, where TMPDIR is the value from --temp-dir.

You can use the config paths command to see the current value.

Cache directory is heavily used by the VFS File Caching mount feature, but also by serve, GUI and other parts of rclone.

--check-first

If this flag is set then in a sync, copy or move, rclone will do all the checks to see whether files need to be transferred before doing any of the transfers. Normally rclone would start running transfers as soon as possible.

This flag can be useful on IO limited systems where transfers interfere with checking.

It can also be useful to ensure perfect ordering when using --order-by.

If both --check-first and --order-by are set when doing rclone move then rclone will use the transfer thread to delete source files which don't need transferring. This will enable perfect ordering of the transfers and deletes but will cause the transfer stats to have more items in than expected.

Using this flag can use more memory as it effectively sets --max-backlog to infinite. This means that all the info on the objects to transfer is held in memory before the transfers start.

--checkers=N

Originally controlling just the number of file checkers to run in parallel, e.g. by rclone copy. Now a fairly universal parallelism control used by rclone in several places.

Note: checkers do the equality checking of files during a sync. For some storage systems (e.g. S3, Swift, Dropbox) this can take a significant amount of time so they are run in parallel.

The default is to run 8 checkers in parallel. However, in case of slow-reacting backends you may need to lower (rather than increase) this default by setting --checkers to 4 or less threads. This is especially advised if you are experiencing backend server crashes during file checking phase (e.g. on subsequent or top-up backups where little or no file copying is done and checking takes up most of the time). Increase this setting only with utmost care, while monitoring your server health and file checking throughput.

-c, --checksum

Normally rclone will look at modification time and size of files to see if they are equal. If you set this flag then rclone will check the file hash and size to determine if files are equal.

This is useful when the remote doesn't support setting modified time and a more accurate sync is desired than just checking the file size.

This is very useful when transferring between remotes which store the same hash type on the object, e.g. Drive and Swift. For details of which remotes support which hash type see the table in the overview section.

Eg rclone --checksum sync s3:/bucket swift:/bucket would run much quicker than without the --checksum flag.

When using this flag, rclone won't update mtimes of remote files if they are incorrect as it would normally.

--color WHEN

Specify when colors (and other ANSI codes) should be added to the output.

AUTO (default) only allows ANSI codes when the output is a terminal

NEVER never allow ANSI codes

ALWAYS always add ANSI codes, regardless of the output format (terminal or file)

--compare-dest=DIR

When using sync, copy or move DIR is checked in addition to the destination for files. If a file identical to the source is found that file is NOT copied from source. This is useful to copy just files that have changed since the last backup.

You must use the same remote as the destination of the sync. The compare directory must not overlap the destination directory.

See --copy-dest and --backup-dir.

--config=CONFIG_FILE

Specify the location of the rclone configuration file, to override the default. E.g. rclone config --config="rclone.conf".

The exact default is a bit complex to describe, due to changes introduced through different versions of rclone while preserving backwards compatibility, but in most cases it is as simple as:

The complete logic is as follows: Rclone will look for an existing configuration file in any of the following locations, in priority order:

  1. rclone.conf (in program directory, where rclone executable is)
  2. %APPDATA%/rclone/rclone.conf (only on Windows)
  3. $XDG_CONFIG_HOME/rclone/rclone.conf (on all systems, including Windows)
  4. ~/.config/rclone/rclone.conf (see below for explanation of ~ symbol)
  5. ~/.rclone.conf

If no existing configuration file is found, then a new one will be created in the following location:

The ~ symbol in paths above represent the home directory of the current user on any OS, and the value is defined as following:

If you run rclone config file you will see where the default location is for you.

The fact that an existing file rclone.conf in the same directory as the rclone executable is always preferred, means that it is easy to run in "portable" mode by downloading rclone executable to a writable directory and then create an empty file rclone.conf in the same directory.

If the location is set to empty string "" or path to a file with name notfound, or the os null device represented by value NUL on Windows and /dev/null on Unix systems, then rclone will keep the config file in memory only.

The file format is basic INI: Sections of text, led by a [section] header and followed by key=value entries on separate lines. In rclone each remote is represented by its own section, where the section name defines the name of the remote. Options are specified as the key=value entries, where the key is the option name without the --backend- prefix, in lowercase and with _ instead of -. E.g. option --mega-hard-delete corresponds to key hard_delete. Only backend options can be specified. A special, and required, key type identifies the storage system, where the value is the internal lowercase name as returned by command rclone help backends. Comments are indicated by ; or # at the beginning of a line.

Example:

[megaremote]
type = mega
user = you@example.com
pass = PDPcQVVjVtzFY-GTdDFozqBhTdsPg3qH

Note that passwords are in obscured form. Also, many storage systems uses token-based authentication instead of passwords, and this requires additional steps. It is easier, and safer, to use the interactive command rclone config instead of manually editing the configuration file.

The configuration file will typically contain login information, and should therefore have restricted permissions so that only the current user can read it. Rclone tries to ensure this when it writes the file. You may also choose to encrypt the file.

When token-based authentication are used, the configuration file must be writable, because rclone needs to update the tokens inside it.

To reduce risk of corrupting an existing configuration file, rclone will not write directly to it when saving changes. Instead it will first write to a new, temporary, file. If a configuration file already existed, it will (on Unix systems) try to mirror its permissions to the new file. Then it will rename the existing file to a temporary name as backup. Next, rclone will rename the new file to the correct name, before finally cleaning up by deleting the backup file.

If the configuration file path used by rclone is a symbolic link, then this will be evaluated and rclone will write to the resolved path, instead of overwriting the symbolic link. Temporary files used in the process (described above) will be written to the same parent directory as that of the resolved configuration file, but if this directory is also a symbolic link it will not be resolved and the temporary files will be written to the location of the directory symbolic link.

--contimeout=TIME

Set the connection timeout. This should be in go time format which looks like 5s for 5 seconds, 10m for 10 minutes, or 3h30m.

The connection timeout is the amount of time rclone will wait for a connection to go through to a remote object storage system. It is 1m by default.

--copy-dest=DIR

When using sync, copy or move DIR is checked in addition to the destination for files. If a file identical to the source is found that file is server-side copied from DIR to the destination. This is useful for incremental backup.

The remote in use must support server-side copy and you must use the same remote as the destination of the sync. The compare directory must not overlap the destination directory.

See --compare-dest and --backup-dir.

--dedupe-mode MODE

Mode to run dedupe command in. One of interactive, skip, first, newest, oldest, rename. The default is interactive.
See the dedupe command for more information as to what these options mean.

--default-time TIME

If a file or directory does have a modification time rclone can read then rclone will display this fixed time instead.

The default is 2000-01-01 00:00:00 UTC. This can be configured in any of the ways shown in the time or duration options.

For example --default-time 2020-06-01 to set the default time to the 1st of June 2020 or --default-time 0s to set the default time to the time rclone started up.

--disable FEATURE,FEATURE,...

This disables a comma separated list of optional features. For example to disable server-side move and server-side copy use:

--disable move,copy

The features can be put in any case.

To see a list of which features can be disabled use:

--disable help

The features a remote has can be seen in JSON format with:

rclone backend features remote:

See the overview features and optional features to get an idea of which feature does what.

Note that some features can be set to true if they are true/false feature flag features by prefixing them with !. For example the CaseInsensitive feature can be forced to false with --disable CaseInsensitive and forced to true with --disable '!CaseInsensitive'. In general it isn't a good idea doing this but it may be useful in extremis.

(Note that ! is a shell command which you will need to escape with single quotes or a backslash on unix like platforms.)

This flag can be useful for debugging and in exceptional circumstances (e.g. Google Drive limiting the total volume of Server Side Copies to 100 GiB/day).

--disable-http2

This stops rclone from trying to use HTTP/2 if available. This can sometimes speed up transfers due to a problem in the Go standard library.

--dscp VALUE

Specify a DSCP value or name to use in connections. This could help QoS system to identify traffic class. BE, EF, DF, LE, CSx and AFxx are allowed.

See the description of differentiated services to get an idea of this field. Setting this to 1 (LE) to identify the flow to SCAVENGER class can avoid occupying too much bandwidth in a network with DiffServ support (RFC 8622).

For example, if you configured QoS on router to handle LE properly. Running:

rclone copy --dscp LE from:/from to:/to

would make the priority lower than usual internet flows.

This option has no effect on Windows (see golang/go#42728).

-n, --dry-run

Do a trial run with no permanent changes. Use this to see what rclone would do without actually doing it. Useful when setting up the sync command which deletes files in the destination.

--expect-continue-timeout=TIME

This specifies the amount of time to wait for a server's first response headers after fully writing the request headers if the request has an "Expect: 100-continue" header. Not all backends support using this.

Zero means no timeout and causes the body to be sent immediately, without waiting for the server to approve. This time does not include the time to send the request header.

The default is 1s. Set to 0 to disable.

--error-on-no-transfer

By default, rclone will exit with return code 0 if there were no errors.

This option allows rclone to return exit code 9 if no files were transferred between the source and destination. This allows using rclone in scripts, and triggering follow-on actions if data was copied, or skipping if not.

NB: Enabling this option turns a usually non-fatal error into a potentially fatal one - please check and adjust your scripts accordingly!

--fs-cache-expire-duration=TIME

When using rclone via the API rclone caches created remotes for 5 minutes by default in the "fs cache". This means that if you do repeated actions on the same remote then rclone won't have to build it again from scratch, which makes it more efficient.

This flag sets the time that the remotes are cached for. If you set it to 0 (or negative) then rclone won't cache the remotes at all.

Note that if you use some flags, eg --backup-dir and if this is set to 0 rclone may build two remotes (one for the source or destination and one for the --backup-dir where it may have only built one before.

--fs-cache-expire-interval=TIME

This controls how often rclone checks for cached remotes to expire. See the --fs-cache-expire-duration documentation above for more info. The default is 60s, set to 0 to disable expiry.

Add an HTTP header for all transactions. The flag can be repeated to add multiple headers.

If you want to add headers only for uploads use --header-upload and if you want to add headers only for downloads use --header-download.

This flag is supported for all HTTP based backends even those not supported by --header-upload and --header-download so may be used as a workaround for those with care.

rclone ls remote:test --header "X-Rclone: Foo" --header "X-LetMeIn: Yes"

--header-download

Add an HTTP header for all download transactions. The flag can be repeated to add multiple headers.

rclone sync --interactive s3:test/src ~/dst --header-download "X-Amz-Meta-Test: Foo" --header-download "X-Amz-Meta-Test2: Bar"

See the GitHub issue here for currently supported backends.

--header-upload

Add an HTTP header for all upload transactions. The flag can be repeated to add multiple headers.

rclone sync --interactive ~/src s3:test/dst --header-upload "Content-Disposition: attachment; filename='cool.html'" --header-upload "X-Amz-Meta-Test: FooBar"

See the GitHub issue here for currently supported backends.

--human-readable

Rclone commands output values for sizes (e.g. number of bytes) and counts (e.g. number of files) either as raw numbers, or in human-readable format.

In human-readable format the values are scaled to larger units, indicated with a suffix shown after the value, and rounded to three decimals. Rclone consistently uses binary units (powers of 2) for sizes and decimal units (powers of 10) for counts. The unit prefix for size is according to IEC standard notation, e.g. Ki for kibi. Used with byte unit, 1 KiB means 1024 Byte. In list type of output, only the unit prefix appended to the value (e.g. 9.762Ki), while in more textual output the full unit is shown (e.g. 9.762 KiB). For counts the SI standard notation is used, e.g. prefix k for kilo. Used with file counts, 1k means 1000 files.

The various list commands output raw numbers by default. Option --human-readable will make them output values in human-readable format instead (with the short unit prefix).

The about command outputs human-readable by default, with a command-specific option --full to output the raw numbers instead.

Command size outputs both human-readable and raw numbers in the same output.

The tree command also considers --human-readable, but it will not use the exact same notation as the other commands: It rounds to one decimal, and uses single letter suffix, e.g. K instead of Ki. The reason for this is that it relies on an external library.

The interactive command ncdu shows human-readable by default, and responds to key u for toggling human-readable format.

--ignore-case-sync

Using this option will cause rclone to ignore the case of the files when synchronizing so files will not be copied/synced when the existing filenames are the same, even if the casing is different.

--ignore-checksum

Normally rclone will check that the checksums of transferred files match, and give an error "corrupted on transfer" if they don't.

You can use this option to skip that check. You should only use it if you have had the "corrupted on transfer" error message and you are sure you might want to transfer potentially corrupted data.

--ignore-existing

Using this option will make rclone unconditionally skip all files that exist on the destination, no matter the content of these files.

While this isn't a generally recommended option, it can be useful in cases where your files change due to encryption. However, it cannot correct partial transfers in case a transfer was interrupted.

When performing a move/moveto command, this flag will leave skipped files in the source location unchanged when a file with the same name exists on the destination.

--ignore-size

Normally rclone will look at modification time and size of files to see if they are equal. If you set this flag then rclone will check only the modification time. If --checksum is set then it only checks the checksum.

It will also cause rclone to skip verifying the sizes are the same after transfer.

This can be useful for transferring files to and from OneDrive which occasionally misreports the size of image files (see #399 for more info).

-I, --ignore-times

Using this option will cause rclone to unconditionally upload all files regardless of the state of files on the destination.

Normally rclone would skip any files that have the same modification time and are the same size (or have the same checksum if using --checksum).

--immutable

Treat source and destination files as immutable and disallow modification.

With this option set, files will be created and deleted as requested, but existing files will never be updated. If an existing file does not match between the source and destination, rclone will give the error Source and destination exist but do not match: immutable file modified.

Note that only commands which transfer files (e.g. sync, copy, move) are affected by this behavior, and only modification is disallowed. Files may still be deleted explicitly (e.g. delete, purge) or implicitly (e.g. sync, move). Use copy --immutable if it is desired to avoid deletion as well as modification.

This can be useful as an additional layer of protection for immutable or append-only data sets (notably backup archives), where modification implies corruption and should not be propagated.

--inplace

The --inplace flag changes the behaviour of rclone when uploading files to some backends (backends with the PartialUploads feature flag set) such as:

Without --inplace (the default) rclone will first upload to a temporary file with an extension like this where XXXXXX represents a random string.

original-file-name.XXXXXX.partial

(rclone will make sure the final name is no longer than 100 characters by truncating the original-file-name part if necessary).

When the upload is complete, rclone will rename the .partial file to the correct name, overwriting any existing file at that point. If the upload fails then the .partial file will be deleted.

This prevents other users of the backend from seeing partially uploaded files in their new names and prevents overwriting the old file until the new one is completely uploaded.

If the --inplace flag is supplied, rclone will upload directly to the final name without creating a .partial file.

This means that an incomplete file will be visible in the directory listings while the upload is in progress and any existing files will be overwritten as soon as the upload starts. If the transfer fails then the file will be deleted. This can cause data loss of the existing file if the transfer fails.

Note that on the local file system if you don't use --inplace hard links (Unix only) will be broken. And if you do use --inplace you won't be able to update in use executables.

Note also that versions of rclone prior to v1.63.0 behave as if the --inplace flag is always supplied.

-i, --interactive

This flag can be used to tell rclone that you wish a manual confirmation before destructive operations.

It is recommended that you use this flag while learning rclone especially with rclone sync.

For example

$ rclone delete --interactive /tmp/dir
rclone: delete "important-file.txt"?
y) Yes, this is OK (default)
n) No, skip this
s) Skip all delete operations with no more questions
!) Do all delete operations with no more questions
q) Exit rclone now.
y/n/s/!/q> n

The options mean

--leave-root

During rmdirs it will not remove root directory, even if it's empty.

--log-file=FILE

Log all of rclone's output to FILE. This is not active by default. This can be useful for tracking down problems with syncs in combination with the -v flag. See the Logging section for more info.

If FILE exists then rclone will append to it.

Note that if you are using the logrotate program to manage rclone's logs, then you should use the copytruncate option as rclone doesn't have a signal to rotate logs.

--log-format LIST

Comma separated list of log format options. Accepted options are date, time, microseconds, pid, longfile, shortfile, UTC. Any other keywords will be silently ignored. pid will tag log messages with process identifier which useful with rclone mount --daemon. Other accepted options are explained in the go documentation. The default log format is "date,time".

--log-level LEVEL

This sets the log level for rclone. The default log level is NOTICE.

DEBUG is equivalent to -vv. It outputs lots of debug info - useful for bug reports and really finding out what rclone is doing.

INFO is equivalent to -v. It outputs information about each transfer and prints stats once a minute by default.

NOTICE is the default log level if no logging flags are supplied. It outputs very little when things are working normally. It outputs warnings and significant events.

ERROR is equivalent to -q. It only outputs error messages.

--use-json-log

This switches the log format to JSON for rclone. The fields of json log are level, msg, source, time.

--low-level-retries NUMBER

This controls the number of low level retries rclone does.

A low level retry is used to retry a failing operation - typically one HTTP request. This might be uploading a chunk of a big file for example. You will see low level retries in the log with the -v flag.

This shouldn't need to be changed from the default in normal operations. However, if you get a lot of low level retries you may wish to reduce the value so rclone moves on to a high level retry (see the --retries flag) quicker.

Disable low level retries with --low-level-retries 1.

--max-backlog=N

This is the maximum allowable backlog of files in a sync/copy/move queued for being checked or transferred.

This can be set arbitrarily large. It will only use memory when the queue is in use. Note that it will use in the order of N KiB of memory when the backlog is in use.

Setting this large allows rclone to calculate how many files are pending more accurately, give a more accurate estimated finish time and make --order-by work more accurately.

Setting this small will make rclone more synchronous to the listings of the remote which may be desirable.

Setting this to a negative number will make the backlog as large as possible.

--max-delete=N

This tells rclone not to delete more than N files. If that limit is exceeded then a fatal error will be generated and rclone will stop the operation in progress.

--max-delete-size=SIZE

Rclone will stop deleting files when the total size of deletions has reached the size specified. It defaults to off.

If that limit is exceeded then a fatal error will be generated and rclone will stop the operation in progress.

--max-depth=N

This modifies the recursion depth for all the commands except purge.

So if you do rclone --max-depth 1 ls remote:path you will see only the files in the top level directory. Using --max-depth 2 means you will see all the files in first two directory levels and so on.

For historical reasons the lsd command defaults to using a --max-depth of 1 - you can override this with the command line flag.

You can use this command to disable recursion (with --max-depth 1).

Note that if you use this with sync and --delete-excluded the files not recursed through are considered excluded and will be deleted on the destination. Test first with --dry-run if you are not sure what will happen.

--max-duration=TIME

Rclone will stop transferring when it has run for the duration specified. Defaults to off.

When the limit is reached all transfers will stop immediately. Use --cutoff-mode to modify this behaviour.

Rclone will exit with exit code 10 if the duration limit is reached.

--max-transfer=SIZE

Rclone will stop transferring when it has reached the size specified. Defaults to off.

When the limit is reached all transfers will stop immediately. Use --cutoff-mode to modify this behaviour.

Rclone will exit with exit code 8 if the transfer limit is reached.

--cutoff-mode=hard|soft|cautious

This modifies the behavior of --max-transfer and --max-duration Defaults to --cutoff-mode=hard.

Specifying --cutoff-mode=hard will stop transferring immediately when Rclone reaches the limit.

Specifying --cutoff-mode=soft will stop starting new transfers when Rclone reaches the limit.

Specifying --cutoff-mode=cautious will try to prevent Rclone from reaching the limit. Only applicable for --max-transfer

-M, --metadata

Setting this flag enables rclone to copy the metadata from the source to the destination. For local backends this is ownership, permissions, xattr etc. See the #metadata for more info.

--metadata-set key=value

Add metadata key = value when uploading. This can be repeated as many times as required. See the #metadata for more info.

--modify-window=TIME

When checking whether a file has been modified, this is the maximum allowed time difference that a file can have and still be considered equivalent.

The default is 1ns unless this is overridden by a remote. For example OS X only stores modification times to the nearest second so if you are reading and writing to an OS X filing system this will be 1s by default.

This command line flag allows you to override that computed default.

--multi-thread-write-buffer-size=SIZE

When transferring with multiple threads, rclone will buffer SIZE bytes in memory before writing to disk for each thread.

This can improve performance if the underlying filesystem does not deal well with a lot of small writes in different positions of the file, so if you see transfers being limited by disk write speed, you might want to experiment with different values. Specially for magnetic drives and remote file systems a higher value can be useful.

Nevertheless, the default of 128k should be fine for almost all use cases, so before changing it ensure that network is not really your bottleneck.

As a final hint, size is not the only factor: block size (or similar concept) can have an impact. In one case, we observed that exact multiples of 16k performed much better than other values.

--multi-thread-chunk-size=SizeSuffix

Normally the chunk size for multi thread transfers is set by the backend. However some backends such as local and smb (which implement OpenWriterAt but not OpenChunkWriter) don't have a natural chunk size.

In this case the value of this option is used (default 64Mi).

--multi-thread-cutoff=SIZE

When transferring files above SIZE to capable backends, rclone will use multiple threads to transfer the file (default 256M).

Capable backends are marked in the overview as MultithreadUpload. (They need to implement either the OpenWriterAt or OpenChunkedWriter internal interfaces). These include include, local, s3, azureblob, b2, oracleobjectstorage and smb at the time of writing.

On the local disk, rclone preallocates the file (using fallocate(FALLOC_FL_KEEP_SIZE) on unix or NTSetInformationFile on Windows both of which takes no time) then each thread writes directly into the file at the correct place. This means that rclone won't create fragmented or sparse files and there won't be any assembly time at the end of the transfer.

The number of threads used to transfer is controlled by --multi-thread-streams.

Use -vv if you wish to see info about the threads.

This will work with the sync/copy/move commands and friends copyto/moveto. Multi thread transfers will be used with rclone mount and rclone serve if --vfs-cache-mode is set to writes or above.

NB that this only works with supported backends as the destination but will work with any backend as the source.

NB that multi-thread copies are disabled for local to local copies as they are faster without unless --multi-thread-streams is set explicitly.

NB on Windows using multi-thread transfers to the local disk will cause the resulting files to be sparse. Use --local-no-sparse to disable sparse files (which may cause long delays at the start of transfers) or disable multi-thread transfers with --multi-thread-streams 0

--multi-thread-streams=N

When using multi thread transfers (see above --multi-thread-cutoff) this sets the number of streams to use. Set to 0 to disable multi thread transfers (Default 4).

If the backend has a --backend-upload-concurrency setting (eg --s3-upload-concurrency) then this setting will be used as the number of transfers instead if it is larger than the value of --multi-thread-streams or --multi-thread-streams isn't set.

--no-check-dest

The --no-check-dest can be used with move or copy and it causes rclone not to check the destination at all when copying files.

This means that:

This flag is useful to minimise the transactions if you know that none of the files are on the destination.

This is a specialized flag which should be ignored by most users!

--no-gzip-encoding

Don't set Accept-Encoding: gzip. This means that rclone won't ask the server for compressed files automatically. Useful if you've set the server to return files with Content-Encoding: gzip but you uploaded compressed files.

There is no need to set this in normal operation, and doing so will decrease the network transfer efficiency of rclone.

--no-traverse

The --no-traverse flag controls whether the destination file system is traversed when using the copy or move commands. --no-traverse is not compatible with sync and will be ignored if you supply it with sync.

If you are only copying a small number of files (or are filtering most of the files) and/or have a large number of files on the destination then --no-traverse will stop rclone listing the destination and save time.

However, if you are copying a large number of files, especially if you are doing a copy where lots of the files under consideration haven't changed and won't need copying then you shouldn't use --no-traverse.

See rclone copy for an example of how to use it.

--no-unicode-normalization

Don't normalize unicode characters in filenames during the sync routine.

Sometimes, an operating system will store filenames containing unicode parts in their decomposed form (particularly macOS). Some cloud storage systems will then recompose the unicode, resulting in duplicate files if the data is ever copied back to a local filesystem.

Using this flag will disable that functionality, treating each unicode character as unique. For example, by default é and é will be normalized into the same character. With --no-unicode-normalization they will be treated as unique characters.

--no-update-modtime

When using this flag, rclone won't update modification times of remote files if they are incorrect as it would normally.

This can be used if the remote is being synced with another tool also (e.g. the Google Drive client).

--order-by string

The --order-by flag controls the order in which files in the backlog are processed in rclone sync, rclone copy and rclone move.

The order by string is constructed like this. The first part describes what aspect is being measured:

This can have a modifier appended with a comma:

If the modifier is mixed then it can have an optional percentage (which defaults to 50), e.g. size,mixed,25 which means that 25% of the threads should be taking the smallest items and 75% the largest. The threads which take the smallest first will always take the smallest first and likewise the largest first threads. The mixed mode can be useful to minimise the transfer time when you are transferring a mixture of large and small files - the large files are guaranteed upload threads and bandwidth and the small files will be processed continuously.

If no modifier is supplied then the order is ascending.

For example

If the --order-by flag is not supplied or it is supplied with an empty string then the default ordering will be used which is as scanned. With --checkers 1 this is mostly alphabetical, however with the default --checkers 8 it is somewhat random.

Limitations

The --order-by flag does not do a separate pass over the data. This means that it may transfer some files out of the order specified if

Rclone will do its best to transfer the best file it has so in practice this should not cause a problem. Think of --order-by as being more of a best efforts flag rather than a perfect ordering.

If you want perfect ordering then you will need to specify --check-first which will find all the files which need transferring first before transferring any.

--password-command SpaceSepList

This flag supplies a program which should supply the config password when run. This is an alternative to rclone prompting for the password or setting the RCLONE_CONFIG_PASS variable.

The argument to this should be a command with a space separated list of arguments. If one of the arguments has a space in then enclose it in ", if you want a literal " in an argument then enclose the argument in " and double the ". See CSV encoding for more info.

Eg

--password-command echo hello
--password-command echo "hello with space"
--password-command echo "hello with ""quotes"" and space"

See the Configuration Encryption for more info.

See a Windows PowerShell example on the Wiki.

-P, --progress

This flag makes rclone update the stats in a static block in the terminal providing a realtime overview of the transfer.

Any log messages will scroll above the static block. Log messages will push the static block down to the bottom of the terminal where it will stay.

Normally this is updated every 500mS but this period can be overridden with the --stats flag.

This can be used with the --stats-one-line flag for a simpler display.

Note: On Windows until this bug is fixed all non-ASCII characters will be replaced with . when --progress is in use.

--progress-terminal-title

This flag, when used with -P/--progress, will print the string ETA: %s to the terminal title.

-q, --quiet

This flag will limit rclone's output to error messages only.

--refresh-times

The --refresh-times flag can be used to update modification times of existing files when they are out of sync on backends which don't support hashes.

This is useful if you uploaded files with the incorrect timestamps and you now wish to correct them.

This flag is only useful for destinations which don't support hashes (e.g. crypt).

This can be used any of the sync commands sync, copy or move.

To use this flag you will need to be doing a modification time sync (so not using --size-only or --checksum). The flag will have no effect when using --size-only or --checksum.

If this flag is used when rclone comes to upload a file it will check to see if there is an existing file on the destination. If this file matches the source with size (and checksum if available) but has a differing timestamp then instead of re-uploading it, rclone will update the timestamp on the destination file. If the checksum does not match rclone will upload the new file. If the checksum is absent (e.g. on a crypt backend) then rclone will update the timestamp.

Note that some remotes can't set the modification time without re-uploading the file so this flag is less useful on them.

Normally if you are doing a modification time sync rclone will update modification times without --refresh-times provided that the remote supports checksums and the checksums match on the file. However if the checksums are absent then rclone will upload the file rather than setting the timestamp as this is the safe behaviour.

--retries int

Retry the entire sync if it fails this many times it fails (default 3).

Some remotes can be unreliable and a few retries help pick up the files which didn't get transferred because of errors.

Disable retries with --retries 1.

--retries-sleep=TIME

This sets the interval between each retry specified by --retries

The default is 0. Use 0 to disable.

--server-side-across-configs

Allow server-side operations (e.g. copy or move) to work across different configurations.

This can be useful if you wish to do a server-side copy or move between two remotes which use the same backend but are configured differently.

Note that this isn't enabled by default because it isn't easy for rclone to tell if it will work between any two configurations.

--size-only

Normally rclone will look at modification time and size of files to see if they are equal. If you set this flag then rclone will check only the size.

This can be useful transferring files from Dropbox which have been modified by the desktop sync client which doesn't set checksums of modification times in the same way as rclone.

--stats=TIME

Commands which transfer data (sync, copy, copyto, move, moveto) will print data transfer stats at regular intervals to show their progress.

This sets the interval.

The default is 1m. Use 0 to disable.

If you set the stats interval then all commands can show stats. This can be useful when running other commands, check or mount for example.

Stats are logged at INFO level by default which means they won't show at default log level NOTICE. Use --stats-log-level NOTICE or -v to make them show. See the Logging section for more info on log levels.

Note that on macOS you can send a SIGINFO (which is normally ctrl-T in the terminal) to make the stats print immediately.

--stats-file-name-length integer

By default, the --stats output will truncate file names and paths longer than 40 characters. This is equivalent to providing --stats-file-name-length 40. Use --stats-file-name-length 0 to disable any truncation of file names printed by stats.

--stats-log-level string

Log level to show --stats output at. This can be DEBUG, INFO, NOTICE, or ERROR. The default is INFO. This means at the default level of logging which is NOTICE the stats won't show - if you want them to then use --stats-log-level NOTICE. See the Logging section for more info on log levels.

--stats-one-line

When this is specified, rclone condenses the stats into a single line showing the most important stats only.

--stats-one-line-date

When this is specified, rclone enables the single-line stats and prepends the display with a date string. The default is 2006/01/02 15:04:05 -

--stats-one-line-date-format

When this is specified, rclone enables the single-line stats and prepends the display with a user-supplied date string. The date string MUST be enclosed in quotes. Follow golang specs for date formatting syntax.

--stats-unit=bits|bytes

By default, data transfer rates will be printed in bytes per second.

This option allows the data rate to be printed in bits per second.

Data transfer volume will still be reported in bytes.

The rate is reported as a binary unit, not SI unit. So 1 Mbit/s equals 1,048,576 bit/s and not 1,000,000 bit/s.

The default is bytes.

--suffix=SUFFIX

When using sync, copy or move any files which would have been overwritten or deleted will have the suffix added to them. If there is a file with the same path (after the suffix has been added), then it will be overwritten.

The remote in use must support server-side move or copy and you must use the same remote as the destination of the sync.

This is for use with files to add the suffix in the current directory or with --backup-dir. See --backup-dir for more info.

For example

rclone copy --interactive /path/to/local/file remote:current --suffix .bak

will copy /path/to/local to remote:current, but for any files which would have been updated or deleted have .bak added.

If using rclone sync with --suffix and without --backup-dir then it is recommended to put a filter rule in excluding the suffix otherwise the sync will delete the backup files.

rclone sync --interactive /path/to/local/file remote:current --suffix .bak --exclude "*.bak"

--suffix-keep-extension

When using --suffix, setting this causes rclone put the SUFFIX before the extension of the files that it backs up rather than after.

So let's say we had --suffix -2019-01-01, without the flag file.txt would be backed up to file.txt-2019-01-01 and with the flag it would be backed up to file-2019-01-01.txt. This can be helpful to make sure the suffixed files can still be opened.

If a file has two (or more) extensions and the second (or subsequent) extension is recognised as a valid mime type, then the suffix will go before that extension. So file.tar.gz would be backed up to file-2019-01-01.tar.gz whereas file.badextension.gz would be backed up to file.badextension-2019-01-01.gz.

--syslog

On capable OSes (not Windows or Plan9) send all log output to syslog.

This can be useful for running rclone in a script or rclone mount.

--syslog-facility string

If using --syslog this sets the syslog facility (e.g. KERN, USER). See man syslog for a list of possible facilities. The default facility is DAEMON.

--temp-dir=DIR

Specify the directory rclone will use for temporary files, to override the default. Make sure the directory exists and have accessible permissions.

By default the operating system's temp directory will be used: - On Unix systems, $TMPDIR if non-empty, else /tmp. - On Windows, the first non-empty value from %TMP%, %TEMP%, %USERPROFILE%, or the Windows directory.

When overriding the default with this option, the specified path will be set as value of environment variable TMPDIR on Unix systems and TMP and TEMP on Windows.

You can use the config paths command to see the current value.

--tpslimit float

Limit transactions per second to this number. Default is 0 which is used to mean unlimited transactions per second.

A transaction is roughly defined as an API call; its exact meaning will depend on the backend. For HTTP based backends it is an HTTP PUT/GET/POST/etc and its response. For FTP/SFTP it is a round trip transaction over TCP.

For example, to limit rclone to 10 transactions per second use --tpslimit 10, or to 1 transaction every 2 seconds use --tpslimit 0.5.

Use this when the number of transactions per second from rclone is causing a problem with the cloud storage provider (e.g. getting you banned or rate limited).

This can be very useful for rclone mount to control the behaviour of applications using it.

This limit applies to all HTTP based backends and to the FTP and SFTP backends. It does not apply to the local backend or the Storj backend.

See also --tpslimit-burst.

--tpslimit-burst int

Max burst of transactions for --tpslimit (default 1).

Normally --tpslimit will do exactly the number of transaction per second specified. However if you supply --tps-burst then rclone can save up some transactions from when it was idle giving a burst of up to the parameter supplied.

For example if you provide --tpslimit-burst 10 then if rclone has been idle for more than 10*--tpslimit then it can do 10 transactions very quickly before they are limited again.

This may be used to increase performance of --tpslimit without changing the long term average number of transactions per second.

--track-renames

By default, rclone doesn't keep track of renamed files, so if you rename a file locally then sync it to a remote, rclone will delete the old file on the remote and upload a new copy.

An rclone sync with --track-renames runs like a normal sync, but keeps track of objects which exist in the destination but not in the source (which would normally be deleted), and which objects exist in the source but not the destination (which would normally be transferred). These objects are then candidates for renaming.

After the sync, rclone matches up the source only and destination only objects using the --track-renames-strategy specified and either renames the destination object or transfers the source and deletes the destination object. --track-renames is stateless like all of rclone's syncs.

To use this flag the destination must support server-side copy or server-side move, and to use a hash based --track-renames-strategy (the default) the source and the destination must have a compatible hash.

If the destination does not support server-side copy or move, rclone will fall back to the default behaviour and log an error level message to the console.

Encrypted destinations are not currently supported by --track-renames if --track-renames-strategy includes hash.

Note that --track-renames is incompatible with --no-traverse and that it uses extra memory to keep track of all the rename candidates.

Note also that --track-renames is incompatible with --delete-before and will select --delete-after instead of --delete-during.

--track-renames-strategy (hash,modtime,leaf,size)

This option changes the file matching criteria for --track-renames.

The matching is controlled by a comma separated selection of these tokens:

The default option is hash.

Using --track-renames-strategy modtime,leaf would match files based on modification time, the leaf of the file name and the size only.

Using --track-renames-strategy modtime or leaf can enable --track-renames support for encrypted destinations.

Note that the hash strategy is not supported with encrypted destinations.

--delete-(before,during,after)

This option allows you to specify when files on your destination are deleted when you sync folders.

Specifying the value --delete-before will delete all files present on the destination, but not on the source before starting the transfer of any new or updated files. This uses two passes through the file systems, one for the deletions and one for the copies.

Specifying --delete-during will delete files while checking and uploading files. This is the fastest option and uses the least memory.

Specifying --delete-after (the default value) will delay deletion of files until all new/updated files have been successfully transferred. The files to be deleted are collected in the copy pass then deleted after the copy pass has completed successfully. The files to be deleted are held in memory so this mode may use more memory. This is the safest mode as it will only delete files if there have been no errors subsequent to that. If there have been errors before the deletions start then you will get the message not deleting files as there were IO errors.

--fast-list

When doing anything which involves a directory listing (e.g. sync, copy, ls - in fact nearly every command), rclone normally lists a directory and processes it before using more directory lists to process any subdirectories. This can be parallelised and works very quickly using the least amount of memory.

However, some remotes have a way of listing all files beneath a directory in one (or a small number) of transactions. These tend to be the bucket-based remotes (e.g. S3, B2, GCS, Swift).

If you use the --fast-list flag then rclone will use this method for listing directories. This will have the following consequences for the listing:

rclone should always give identical results with and without --fast-list.

If you pay for transactions and can fit your entire sync listing into memory then --fast-list is recommended. If you have a very big sync to do then don't use --fast-list otherwise you will run out of memory.

If you use --fast-list on a remote which doesn't support it, then rclone will just ignore it.

--timeout=TIME

This sets the IO idle timeout. If a transfer has started but then becomes idle for this long it is considered broken and disconnected.

The default is 5m. Set to 0 to disable.

--transfers=N

The number of file transfers to run in parallel. It can sometimes be useful to set this to a smaller number if the remote is giving a lot of timeouts or bigger if you have lots of bandwidth and a fast remote.

The default is to run 4 file transfers in parallel.

Look at --multi-thread-streams if you would like to control single file transfers.

-u, --update

This forces rclone to skip any files which exist on the destination and have a modified time that is newer than the source file.

This can be useful in avoiding needless transfers when transferring to a remote which doesn't support modification times directly (or when using --use-server-modtime to avoid extra API calls) as it is more accurate than a --size-only check and faster than using --checksum. On such remotes (or when using --use-server-modtime) the time checked will be the uploaded time.

If an existing destination file has a modification time older than the source file's, it will be updated if the sizes are different. If the sizes are the same, it will be updated if the checksum is different or not available.

If an existing destination file has a modification time equal (within the computed modify window) to the source file's, it will be updated if the sizes are different. The checksum will not be checked in this case unless the --checksum flag is provided.

In all other cases the file will not be updated.

Consider using the --modify-window flag to compensate for time skews between the source and the backend, for backends that do not support mod times, and instead use uploaded times. However, if the backend does not support checksums, note that syncing or copying within the time skew window may still result in additional transfers for safety.

--use-mmap

If this flag is set then rclone will use anonymous memory allocated by mmap on Unix based platforms and VirtualAlloc on Windows for its transfer buffers (size controlled by --buffer-size). Memory allocated like this does not go on the Go heap and can be returned to the OS immediately when it is finished with.

If this flag is not set then rclone will allocate and free the buffers using the Go memory allocator which may use more memory as memory pages are returned less aggressively to the OS.

It is possible this does not work well on all platforms so it is disabled by default; in the future it may be enabled by default.

--use-server-modtime

Some object-store backends (e.g, Swift, S3) do not preserve file modification times (modtime). On these backends, rclone stores the original modtime as additional metadata on the object. By default it will make an API call to retrieve the metadata when the modtime is needed by an operation.

Use this flag to disable the extra API call and rely instead on the server's modified time. In cases such as a local to remote sync using --update, knowing the local file is newer than the time it was last uploaded to the remote is sufficient. In those cases, this flag can speed up the process and reduce the number of API calls necessary.

Using this flag on a sync operation without also using --update would cause all files modified at any time other than the last upload time to be uploaded again, which is probably not what you want.

-v, -vv, --verbose

With -v rclone will tell you about each file that is transferred and a small number of significant events.

With -vv rclone will become very verbose telling you about every file it considers and transfers. Please send bug reports with a log with this setting.

When setting verbosity as an environment variable, use RCLONE_VERBOSE=1 or RCLONE_VERBOSE=2 for -v and -vv respectively.

-V, --version

Prints the version number

SSL/TLS options

The outgoing SSL/TLS connections rclone makes can be controlled with these options. For example this can be very useful with the HTTP or WebDAV backends. Rclone HTTP servers have their own set of configuration for SSL/TLS which you can find in their documentation.

--ca-cert stringArray

This loads the PEM encoded certificate authority certificates and uses it to verify the certificates of the servers rclone connects to.

If you have generated certificates signed with a local CA then you will need this flag to connect to servers using those certificates.

--client-cert string

This loads the PEM encoded client side certificate.

This is used for mutual TLS authentication.

The --client-key flag is required too when using this.

--client-key string

This loads the PEM encoded client side private key used for mutual TLS authentication. Used in conjunction with --client-cert.

--no-check-certificate=true/false

--no-check-certificate controls whether a client verifies the server's certificate chain and host name. If --no-check-certificate is true, TLS accepts any certificate presented by the server and any host name in that certificate. In this mode, TLS is susceptible to man-in-the-middle attacks.

This option defaults to false.

This should be used only for testing.

Configuration Encryption

Your configuration file contains information for logging in to your cloud services. This means that you should keep your rclone.conf file in a secure location.

If you are in an environment where that isn't possible, you can add a password to your configuration. This means that you will have to supply the password every time you start rclone.

To add a password to your rclone configuration, execute rclone config.

>rclone config
Current remotes:

e) Edit existing remote
n) New remote
d) Delete remote
s) Set configuration password
q) Quit config
e/n/d/s/q>

Go into s, Set configuration password:

e/n/d/s/q> s
Your configuration is not encrypted.
If you add a password, you will protect your login information to cloud services.
a) Add Password
q) Quit to main menu
a/q> a
Enter NEW configuration password:
password:
Confirm NEW password:
password:
Password set
Your configuration is encrypted.
c) Change Password
u) Unencrypt configuration
q) Quit to main menu
c/u/q>

Your configuration is now encrypted, and every time you start rclone you will have to supply the password. See below for details. In the same menu, you can change the password or completely remove encryption from your configuration.

There is no way to recover the configuration if you lose your password.

rclone uses nacl secretbox which in turn uses XSalsa20 and Poly1305 to encrypt and authenticate your configuration with secret-key cryptography. The password is SHA-256 hashed, which produces the key for secretbox. The hashed password is not stored.

While this provides very good security, we do not recommend storing your encrypted rclone configuration in public if it contains sensitive information, maybe except if you use a very strong password.

If it is safe in your environment, you can set the RCLONE_CONFIG_PASS environment variable to contain your password, in which case it will be used for decrypting the configuration.

You can set this for a session from a script. For unix like systems save this to a file called set-rclone-password:

#!/bin/echo Source this file don't run it

read -s RCLONE_CONFIG_PASS
export RCLONE_CONFIG_PASS

Then source the file when you want to use it. From the shell you would do source set-rclone-password. It will then ask you for the password and set it in the environment variable.

An alternate means of supplying the password is to provide a script which will retrieve the password and print on standard output. This script should have a fully specified path name and not rely on any environment variables. The script is supplied either via --password-command="..." command line argument or via the RCLONE_PASSWORD_COMMAND environment variable.

One useful example of this is using the passwordstore application to retrieve the password:

export RCLONE_PASSWORD_COMMAND="pass rclone/config"

If the passwordstore password manager holds the password for the rclone configuration, using the script method means the password is primarily protected by the passwordstore system, and is never embedded in the clear in scripts, nor available for examination using the standard commands available. It is quite possible with long running rclone sessions for copies of passwords to be innocently captured in log files or terminal scroll buffers, etc. Using the script method of supplying the password enhances the security of the config password considerably.

If you are running rclone inside a script, unless you are using the --password-command method, you might want to disable password prompts. To do that, pass the parameter --ask-password=false to rclone. This will make rclone fail instead of asking for a password if RCLONE_CONFIG_PASS doesn't contain a valid password, and --password-command has not been supplied.

Whenever running commands that may be affected by options in a configuration file, rclone will look for an existing file according to the rules described above, and load any it finds. If an encrypted file is found, this includes decrypting it, with the possible consequence of a password prompt. When executing a command line that you know are not actually using anything from such a configuration file, you can avoid it being loaded by overriding the location, e.g. with one of the documented special values for memory-only configuration. Since only backend options can be stored in configuration files, this is normally unnecessary for commands that do not operate on backends, e.g. genautocomplete. However, it will be relevant for commands that do operate on backends in general, but are used without referencing a stored remote, e.g. listing local filesystem paths, or connection strings: rclone --config="" ls .

Developer options

These options are useful when developing or debugging rclone. There are also some more remote specific options which aren't documented here which are used for testing. These start with remote name e.g. --drive-test-option - see the docs for the remote in question.

--cpuprofile=FILE

Write CPU profile to file. This can be analysed with go tool pprof.

--dump flag,flag,flag

The --dump flag takes a comma separated list of flags to dump info about.

Note that some headers including Accept-Encoding as shown may not be correct in the request and the response may not show Content-Encoding if the go standard libraries auto gzip encoding was in effect. In this case the body of the request will be gunzipped before showing it.

The available flags are:

--dump headers

Dump HTTP headers with Authorization: lines removed. May still contain sensitive info. Can be very verbose. Useful for debugging only.

Use --dump auth if you do want the Authorization: headers.

--dump bodies

Dump HTTP headers and bodies - may contain sensitive info. Can be very verbose. Useful for debugging only.

Note that the bodies are buffered in memory so don't use this for enormous files.

--dump requests

Like --dump bodies but dumps the request bodies and the response headers. Useful for debugging download problems.

--dump responses

Like --dump bodies but dumps the response bodies and the request headers. Useful for debugging upload problems.

--dump auth

Dump HTTP headers - will contain sensitive info such as Authorization: headers - use --dump headers to dump without Authorization: headers. Can be very verbose. Useful for debugging only.

--dump filters

Dump the filters to the output. Useful to see exactly what include and exclude options are filtering on.

--dump goroutines

This dumps a list of the running go-routines at the end of the command to standard output.

--dump openfiles

This dumps a list of the open files at the end of the command. It uses the lsof command to do that so you'll need that installed to use it.

--memprofile=FILE

Write memory profile to file. This can be analysed with go tool pprof.

Filtering

See the filtering section.

Remote control

For the remote control options and for instructions on how to remote control rclone

See the remote control section.

Logging

rclone has 4 levels of logging, ERROR, NOTICE, INFO and DEBUG.

By default, rclone logs to standard error. This means you can redirect standard error and still see the normal output of rclone commands (e.g. rclone ls).

By default, rclone will produce Error and Notice level messages.

If you use the -q flag, rclone will only produce Error messages.

If you use the -v flag, rclone will produce Error, Notice and Info messages.

If you use the -vv flag, rclone will produce Error, Notice, Info and Debug messages.

You can also control the log levels with the --log-level flag.

If you use the --log-file=FILE option, rclone will redirect Error, Info and Debug messages along with standard error to FILE.

If you use the --syslog flag then rclone will log to syslog and the --syslog-facility control which facility it uses.

Rclone prefixes all log messages with their level in capitals, e.g. INFO which makes it easy to grep the log file for different kinds of information.

Exit Code

If any errors occur during the command execution, rclone will exit with a non-zero exit code. This allows scripts to detect when rclone operations have failed.

During the startup phase, rclone will exit immediately if an error is detected in the configuration. There will always be a log message immediately before exiting.

When rclone is running it will accumulate errors as it goes along, and only exit with a non-zero exit code if (after retries) there were still failed transfers. For every error counted there will be a high priority log message (visible with -q) showing the message and which file caused the problem. A high priority message is also shown when starting a retry so the user can see that any previous error messages may not be valid after the retry. If rclone has done a retry it will log a high priority message if the retry was successful.

List of exit codes

Environment Variables

Rclone can be configured entirely using environment variables. These can be used to set defaults for options or config file entries.

Options

Every option in rclone can have its default set by environment variable.

To find the name of the environment variable, first, take the long option name, strip the leading --, change - to _, make upper case and prepend RCLONE_.

For example, to always set --stats 5s, set the environment variable RCLONE_STATS=5s. If you set stats on the command line this will override the environment variable setting.

Or to always use the trash in drive --drive-use-trash, set RCLONE_DRIVE_USE_TRASH=true.

Verbosity is slightly different, the environment variable equivalent of --verbose or -v is RCLONE_VERBOSE=1, or for -vv, RCLONE_VERBOSE=2.

The same parser is used for the options and the environment variables so they take exactly the same form.

The options set by environment variables can be seen with the -vv flag, e.g. rclone version -vv.

Config file

You can set defaults for values in the config file on an individual remote basis. The names of the config items are documented in the page for each backend.

To find the name of the environment variable, you need to set, take RCLONE_CONFIG_ + name of remote + _ + name of config file option and make it all uppercase. Note one implication here is the remote's name must be convertible into a valid environment variable name, so it can only contain letters, digits, or the _ (underscore) character.

For example, to configure an S3 remote named mys3: without a config file (using unix ways of setting environment variables):

$ export RCLONE_CONFIG_MYS3_TYPE=s3
$ export RCLONE_CONFIG_MYS3_ACCESS_KEY_ID=XXX
$ export RCLONE_CONFIG_MYS3_SECRET_ACCESS_KEY=XXX
$ rclone lsd mys3:
          -1 2016-09-21 12:54:21        -1 my-bucket
$ rclone listremotes | grep mys3
mys3:

Note that if you want to create a remote using environment variables you must create the ..._TYPE variable as above.

Note that the name of a remote created using environment variable is case insensitive, in contrast to regular remotes stored in config file as documented above. You must write the name in uppercase in the environment variable, but as seen from example above it will be listed and can be accessed in lowercase, while you can also refer to the same remote in uppercase:

$ rclone lsd mys3:
          -1 2016-09-21 12:54:21        -1 my-bucket
$ rclone lsd MYS3:
          -1 2016-09-21 12:54:21        -1 my-bucket

Note that you can only set the options of the immediate backend, so RCLONE_CONFIG_MYS3CRYPT_ACCESS_KEY_ID has no effect, if myS3Crypt is a crypt remote based on an S3 remote. However RCLONE_S3_ACCESS_KEY_ID will set the access key of all remotes using S3, including myS3Crypt.

Note also that now rclone has connection strings, it is probably easier to use those instead which makes the above example

rclone lsd :s3,access_key_id=XXX,secret_access_key=XXX:

Precedence

The various different methods of backend configuration are read in this order and the first one with a value is used.

So if both --skip-links is supplied on the command line and an environment variable RCLONE_LOCAL_SKIP_LINKS is set, the command line flag will take preference.

The backend configurations set by environment variables can be seen with the -vv flag, e.g. rclone about myRemote: -vv.

For non backend configuration the order is as follows:

Other environment variables

The options set by environment variables can be seen with the -vv and --log-level=DEBUG flags, e.g. rclone version -vv.

Configuring rclone on a remote / headless machine

Some of the configurations (those involving oauth2) require an Internet connected web browser.

If you are trying to set rclone up on a remote or headless box with no browser available on it (e.g. a NAS or a server in a datacenter) then you will need to use an alternative means of configuration. There are two ways of doing it, described below.

Configuring using rclone authorize

On the headless box run rclone config but answer N to the Use web browser to automatically authenticate? question.

...
Remote config
Use web browser to automatically authenticate rclone with remote?
 * Say Y if the machine running rclone has a web browser you can use
 * Say N if running rclone on a (remote) machine without web browser access
If not sure try Y. If Y failed, try N.
y) Yes (default)
n) No
y/n> n
For this to work, you will need rclone available on a machine that has
a web browser available.

For more help and alternate methods see: https://rclone.org/remote_setup/

Execute the following on the machine with the web browser (same rclone
version recommended):

    rclone authorize "amazon cloud drive"

Then paste the result below:
result>

Then on your main desktop machine

rclone authorize "amazon cloud drive"
If your browser doesn't open automatically go to the following link: http://127.0.0.1:53682/auth
Log in and authorize rclone for access
Waiting for code...
Got code
Paste the following into your remote machine --->
SECRET_TOKEN
<---End paste

Then back to the headless box, paste in the code

result> SECRET_TOKEN
--------------------
[acd12]
client_id = 
client_secret = 
token = SECRET_TOKEN
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d>

Configuring by copying the config file

Rclone stores all of its config in a single configuration file. This can easily be copied to configure a remote rclone.

So first configure rclone on your desktop machine with

rclone config

to set up the config file.

Find the config file by running rclone config file, for example

$ rclone config file
Configuration file is stored at:
/home/user/.rclone.conf

Now transfer it to the remote box (scp, cut paste, ftp, sftp, etc.) and place it in the correct place (use rclone config file on the remote box to find out where).

Configuring using SSH Tunnel

Linux and MacOS users can utilize SSH Tunnel to redirect the headless box port 53682 to local machine by using the following command:

ssh -L localhost:53682:localhost:53682 username@remote_server

Then on the headless box run rclone config and answer Y to the Use web browser to automatically authenticate? question.

...
Remote config
Use web browser to automatically authenticate rclone with remote?
 * Say Y if the machine running rclone has a web browser you can use
 * Say N if running rclone on a (remote) machine without web browser access
If not sure try Y. If Y failed, try N.
y) Yes (default)
n) No
y/n> y

Then copy and paste the auth url http://127.0.0.1:53682/auth?state=xxxxxxxxxxxx to the browser on your local machine, complete the auth and it is done.

Filtering, includes and excludes

Filter flags determine which files rclone sync, move, ls, lsl, md5sum, sha1sum, size, delete, check and similar commands apply to.

They are specified in terms of path/file name patterns; path/file lists; file age and size, or presence of a file in a directory. Bucket based remotes without the concept of directory apply filters to object key, age and size in an analogous way.

Rclone purge does not obey filters.

To test filters without risk of damage to data, apply them to rclone ls, or with the --dry-run and -vv flags.

Rclone filter patterns can only be used in filter command line options, not in the specification of a remote.

E.g. rclone copy "remote:dir*.jpg" /path/to/dir does not have a filter effect. rclone copy remote:dir /path/to/dir --include "*.jpg" does.

Important Avoid mixing any two of --include..., --exclude... or --filter... flags in an rclone command. The results might not be what you expect. Instead use a --filter... flag.

Patterns for matching path/file names

Pattern syntax

Here is a formal definition of the pattern syntax, examples are below.

Rclone matching rules follow a glob style:

*         matches any sequence of non-separator (/) characters
**        matches any sequence of characters including / separators
?         matches any single non-separator (/) character
[ [ ! ] { character-range } ]
          character class (must be non-empty)
{ pattern-list }
          pattern alternatives
{{ regexp }}
          regular expression to match
c         matches character c (c != *, **, ?, \, [, {, })
\c        matches reserved character c (c = *, **, ?, \, [, {, }) or character class

character-range:

c         matches character c (c != \, -, ])
\c        matches reserved character c (c = \, -, ])
lo - hi   matches character c for lo <= c <= hi

pattern-list:

pattern { , pattern }
          comma-separated (without spaces) patterns

character classes (see Go regular expression reference) include:

Named character classes (e.g. [\d], [^\d], [\D], [^\D])
Perl character classes (e.g. \s, \S, \w, \W)
ASCII character classes (e.g. [[:alnum:]], [[:alpha:]], [[:punct:]], [[:xdigit:]])

regexp for advanced users to insert a regular expression - see below for more info:

Any re2 regular expression not containing `}}`

If the filter pattern starts with a / then it only matches at the top level of the directory tree, relative to the root of the remote (not necessarily the root of the drive). If it does not start with / then it is matched starting at the end of the path/file name but it only matches a complete path element - it must match from a / separator or the beginning of the path/file.

file.jpg   - matches "file.jpg"
           - matches "directory/file.jpg"
           - doesn't match "afile.jpg"
           - doesn't match "directory/afile.jpg"
/file.jpg  - matches "file.jpg" in the root directory of the remote
           - doesn't match "afile.jpg"
           - doesn't match "directory/file.jpg"

The top level of the remote might not be the top level of the drive.

E.g. for a Microsoft Windows local directory structure

F:
├── bkp
├── data
│   ├── excl
│   │   ├── 123.jpg
│   │   └── 456.jpg
│   ├── incl
│   │   └── document.pdf

To copy the contents of folder data into folder bkp excluding the contents of subfolder exclthe following command treats F:\data and F:\bkp as top level for filtering.

rclone copy F:\data\ F:\bkp\ --exclude=/excl/**

Important Use / in path/file name patterns and not \ even if running on Microsoft Windows.

Simple patterns are case sensitive unless the --ignore-case flag is used.

Without --ignore-case (default)

potato - matches "potato"
       - doesn't match "POTATO"

With --ignore-case

potato - matches "potato"
       - matches "POTATO"

Using regular expressions in filter patterns

The syntax of filter patterns is glob style matching (like bash uses) to make things easy for users. However this does not provide absolute control over the matching, so for advanced users rclone also provides a regular expression syntax.

The regular expressions used are as defined in the Go regular expression reference. Regular expressions should be enclosed in {{ }}. They will match only the last path segment if the glob doesn't start with / or the whole path name if it does. Note that rclone does not attempt to parse the supplied regular expression, meaning that using any regular expression filter will prevent rclone from using directory filter rules, as it will instead check every path against the supplied regular expression(s).

Here is how the {{regexp}} is transformed into an full regular expression to match the entire path:

{{regexp}}  becomes (^|/)(regexp)$
/{{regexp}} becomes ^(regexp)$

Regexp syntax can be mixed with glob syntax, for example

*.{{jpe?g}} to match file.jpg, file.jpeg but not file.png

You can also use regexp flags - to set case insensitive, for example

*.{{(?i)jpg}} to match file.jpg, file.JPG but not file.png

Be careful with wildcards in regular expressions - you don't want them to match path separators normally. To match any file name starting with start and ending with end write

{{start[^/]*end\.jpg}}

Not

{{start.*end\.jpg}}

Which will match a directory called start with a file called end.jpg in it as the .* will match / characters.

Note that you can use -vv --dump filters to show the filter patterns in regexp format - rclone implements the glob patterns by transforming them into regular expressions.

Filter pattern examples

How filter rules are applied to files

Rclone path/file name filters are made up of one or more of the following flags:

There can be more than one instance of individual flags.

Rclone internally uses a combined list of all the include and exclude rules. The order in which rules are processed can influence the result of the filter.

All flags of the same type are processed together in the order above, regardless of what order the different types of flags are included on the command line.

Multiple instances of the same flag are processed from left to right according to their position in the command line.

To mix up the order of processing includes and excludes use --filter... flags.

Within --include-from, --exclude-from and --filter-from flags rules are processed from top to bottom of the referenced file.

If there is an --include or --include-from flag specified, rclone implies a - ** rule which it adds to the bottom of the internal rule list. Specifying a + rule with a --filter... flag does not imply that rule.

Each path/file name passed through rclone is matched against the combined filter list. At first match to a rule the path/file name is included or excluded and no further filter rules are processed for that path/file.

If rclone does not find a match, after testing against all rules (including the implied rule if appropriate), the path/file name is included.

Any path/file included at that stage is processed by the rclone command.

--files-from and --files-from-raw flags over-ride and cannot be combined with other filter options.

To see the internal combined rule list, in regular expression form, for a command add the --dump filters flag. Running an rclone command with --dump filters and -vv flags lists the internal filter elements and shows how they are applied to each source path/file. There is not currently a means provided to pass regular expression filter options into rclone directly though character class filter rules contain character classes. Go regular expression reference

How filter rules are applied to directories

Rclone commands are applied to path/file names not directories. The entire contents of a directory can be matched to a filter by the pattern directory/* or recursively by directory/**.

Directory filter rules are defined with a closing / separator.

E.g. /directory/subdirectory/ is an rclone directory filter rule.

Rclone commands can use directory filter rules to determine whether they recurse into subdirectories. This potentially optimises access to a remote by avoiding listing unnecessary directories. Whether optimisation is desirable depends on the specific filter rules and source remote content.

If any regular expression filters are in use, then no directory recursion optimisation is possible, as rclone must check every path against the supplied regular expression(s).

Directory recursion optimisation occurs if either:

Rclone commands imply directory filter rules from path/file filter rules. To view the directory filter rules rclone has implied for a command specify the --dump filters flag.

E.g. for an include rule

/a/*.jpg

Rclone implies the directory include rule

/a/

Directory filter rules specified in an rclone command can limit the scope of an rclone command but path/file filters still have to be specified.

E.g. rclone ls remote: --include /directory/ will not match any files. Because it is an --include option the --exclude ** rule is implied, and the /directory/ pattern serves only to optimise access to the remote by ignoring everything outside of that directory.

E.g. rclone ls remote: --filter-from filter-list.txt with a file filter-list.txt:

- /dir1/
- /dir2/
+ *.pdf
- **

All files in directories dir1 or dir2 or their subdirectories are completely excluded from the listing. Only files of suffix pdf in the root of remote: or its subdirectories are listed. The - ** rule prevents listing of any path/files not previously matched by the rules above.

Option exclude-if-present creates a directory exclude rule based on the presence of a file in a directory and takes precedence over other rclone directory filter rules.

When using pattern list syntax, if a pattern item contains either / or **, then rclone will not able to imply a directory filter rule from this pattern list.

E.g. for an include rule

{dir1/**,dir2/**}

Rclone will match files below directories dir1 or dir2 only, but will not be able to use this filter to exclude a directory dir3 from being traversed.

Directory recursion optimisation may affect performance, but normally not the result. One exception to this is sync operations with option --create-empty-src-dirs, where any traversed empty directories will be created. With the pattern list example {dir1/**,dir2/**} above, this would create an empty directory dir3 on destination (when it exists on source). Changing the filter to {dir1,dir2}/**, or splitting it into two include rules --include dir1/** --include dir2/**, will match the same files while also filtering directories, with the result that an empty directory dir3 will no longer be created.

--exclude - Exclude files matching pattern

Excludes path/file names from an rclone command based on a single exclude rule.

This flag can be repeated. See above for the order filter flags are processed in.

--exclude should not be used with --include, --include-from, --filter or --filter-from flags.

--exclude has no effect when combined with --files-from or --files-from-raw flags.

E.g. rclone ls remote: --exclude *.bak excludes all .bak files from listing.

E.g. rclone size remote: "--exclude /dir/**" returns the total size of all files on remote: excluding those in root directory dir and sub directories.

E.g. on Microsoft Windows rclone ls remote: --exclude "*\[{JP,KR,HK}\]*" lists the files in remote: without [JP] or [KR] or [HK] in their name. Quotes prevent the shell from interpreting the \ characters.\ characters escape the [ and ] so an rclone filter treats them literally rather than as a character-range. The { and } define an rclone pattern list. For other operating systems single quotes are required ie rclone ls remote: --exclude '*\[{JP,KR,HK}\]*'

--exclude-from - Read exclude patterns from file

Excludes path/file names from an rclone command based on rules in a named file. The file contains a list of remarks and pattern rules.

For an example exclude-file.txt:

# a sample exclude rule file
*.bak
file2.jpg

rclone ls remote: --exclude-from exclude-file.txt lists the files on remote: except those named file2.jpg or with a suffix .bak. That is equivalent to rclone ls remote: --exclude file2.jpg --exclude "*.bak".

This flag can be repeated. See above for the order filter flags are processed in.

The --exclude-from flag is useful where multiple exclude filter rules are applied to an rclone command.

--exclude-from should not be used with --include, --include-from, --filter or --filter-from flags.

--exclude-from has no effect when combined with --files-from or --files-from-raw flags.

--exclude-from followed by - reads filter rules from standard input.

--include - Include files matching pattern

Adds a single include rule based on path/file names to an rclone command.

This flag can be repeated. See above for the order filter flags are processed in.

--include has no effect when combined with --files-from or --files-from-raw flags.

--include implies --exclude ** at the end of an rclone internal filter list. Therefore if you mix --include and --include-from flags with --exclude, --exclude-from, --filter or --filter-from, you must use include rules for all the files you want in the include statement. For more flexibility use the --filter-from flag.

E.g. rclone ls remote: --include "*.{png,jpg}" lists the files on remote: with suffix .png and .jpg. All other files are excluded.

E.g. multiple rclone copy commands can be combined with --include and a pattern-list.

rclone copy /vol1/A remote:A
rclone copy /vol1/B remote:B

is equivalent to:

rclone copy /vol1 remote: --include "{A,B}/**"

E.g. rclone ls remote:/wheat --include "??[^[:punct:]]*" lists the files remote: directory wheat (and subdirectories) whose third character is not punctuation. This example uses an ASCII character class.

--include-from - Read include patterns from file

Adds path/file names to an rclone command based on rules in a named file. The file contains a list of remarks and pattern rules.

For an example include-file.txt:

# a sample include rule file
*.jpg
file2.avi

rclone ls remote: --include-from include-file.txt lists the files on remote: with name file2.avi or suffix .jpg. That is equivalent to rclone ls remote: --include file2.avi --include "*.jpg".

This flag can be repeated. See above for the order filter flags are processed in.

The --include-from flag is useful where multiple include filter rules are applied to an rclone command.

--include-from implies --exclude ** at the end of an rclone internal filter list. Therefore if you mix --include and --include-from flags with --exclude, --exclude-from, --filter or --filter-from, you must use include rules for all the files you want in the include statement. For more flexibility use the --filter-from flag.

--exclude-from has no effect when combined with --files-from or --files-from-raw flags.

--exclude-from followed by - reads filter rules from standard input.

--filter - Add a file-filtering rule

Specifies path/file names to an rclone command, based on a single include or exclude rule, in + or - format.

This flag can be repeated. See above for the order filter flags are processed in.

--filter + differs from --include. In the case of --include rclone implies an --exclude * rule which it adds to the bottom of the internal rule list. --filter...+ does not imply that rule.

--filter has no effect when combined with --files-from or --files-from-raw flags.

--filter should not be used with --include, --include-from, --exclude or --exclude-from flags.

E.g. rclone ls remote: --filter "- *.bak" excludes all .bak files from a list of remote:.

--filter-from - Read filtering patterns from a file

Adds path/file names to an rclone command based on rules in a named file. The file contains a list of remarks and pattern rules. Include rules start with + and exclude rules with -. ! clears existing rules. Rules are processed in the order they are defined.

This flag can be repeated. See above for the order filter flags are processed in.

Arrange the order of filter rules with the most restrictive first and work down.

E.g. for filter-file.txt:

# a sample filter rule file
- secret*.jpg
+ *.jpg
+ *.png
+ file2.avi
- /dir/Trash/**
+ /dir/**
# exclude everything else
- *

rclone ls remote: --filter-from filter-file.txt lists the path/files on remote: including all jpg and png files, excluding any matching secret*.jpg and including file2.avi. It also includes everything in the directory dir at the root of remote, except remote:dir/Trash which it excludes. Everything else is excluded.

E.g. for an alternative filter-file.txt:

- secret*.jpg
+ *.jpg
+ *.png
+ file2.avi
- *

Files file1.jpg, file3.png and file2.avi are listed whilst secret17.jpg and files without the suffix .jpgor.png` are excluded.

E.g. for an alternative filter-file.txt:

+ *.jpg
+ *.gif
!
+ 42.doc
- *

Only file 42.doc is listed. Prior rules are cleared by the !.

--files-from - Read list of source-file names

Adds path/files to an rclone command from a list in a named file. Rclone processes the path/file names in the order of the list, and no others.

Other filter flags (--include, --include-from, --exclude, --exclude-from, --filter and --filter-from) are ignored when --files-from is used.

--files-from expects a list of files as its input. Leading or trailing whitespace is stripped from the input lines. Lines starting with # or ; are ignored.

Rclone commands with a --files-from flag traverse the remote, treating the names in --files-from as a set of filters.

If the --no-traverse and --files-from flags are used together an rclone command does not traverse the remote. Instead it addresses each path/file named in the file individually. For each path/file name, that requires typically 1 API call. This can be efficient for a short --files-from list and a remote containing many files.

Rclone commands do not error if any names in the --files-from file are missing from the source remote.

The --files-from flag can be repeated in a single rclone command to read path/file names from more than one file. The files are read from left to right along the command line.

Paths within the --files-from file are interpreted as starting with the root specified in the rclone command. Leading / separators are ignored. See --files-from-raw if you need the input to be processed in a raw manner.

E.g. for a file files-from.txt:

# comment
file1.jpg
subdir/file2.jpg

rclone copy --files-from files-from.txt /home/me/pics remote:pics copies the following, if they exist, and only those files.

/home/me/pics/file1.jpg        → remote:pics/file1.jpg
/home/me/pics/subdir/file2.jpg → remote:pics/subdir/file2.jpg

E.g. to copy the following files referenced by their absolute paths:

/home/user1/42
/home/user1/dir/ford
/home/user2/prefect

First find a common subdirectory - in this case /home and put the remaining files in files-from.txt with or without leading /, e.g.

user1/42
user1/dir/ford
user2/prefect

Then copy these to a remote:

rclone copy --files-from files-from.txt /home remote:backup

The three files are transferred as follows:

/home/user1/42       → remote:backup/user1/important
/home/user1/dir/ford → remote:backup/user1/dir/file
/home/user2/prefect  → remote:backup/user2/stuff

Alternatively if / is chosen as root files-from.txt will be:

/home/user1/42
/home/user1/dir/ford
/home/user2/prefect

The copy command will be:

rclone copy --files-from files-from.txt / remote:backup

Then there will be an extra home directory on the remote:

/home/user1/42       → remote:backup/home/user1/42
/home/user1/dir/ford → remote:backup/home/user1/dir/ford
/home/user2/prefect  → remote:backup/home/user2/prefect

--files-from-raw - Read list of source-file names without any processing

This flag is the same as --files-from except that input is read in a raw manner. Lines with leading / trailing whitespace, and lines starting with ; or # are read without any processing. rclone lsf has a compatible format that can be used to export file lists from remotes for input to --files-from-raw.

--ignore-case - make searches case insensitive

By default, rclone filter patterns are case sensitive. The --ignore-case flag makes all of the filters patterns on the command line case insensitive.

E.g. --include "zaphod.txt" does not match a file Zaphod.txt. With --ignore-case a match is made.

Quoting shell metacharacters

Rclone commands with filter patterns containing shell metacharacters may not as work as expected in your shell and may require quoting.

E.g. linux, OSX (* metacharacter)

Microsoft Windows expansion is done by the command, not shell, so --include *.jpg does not require quoting.

If the rclone error Command .... needs .... arguments maximum: you provided .... non flag arguments: is encountered, the cause is commonly spaces within the name of a remote or flag value. The fix then is to quote values containing spaces.

Other filters

--min-size - Don't transfer any file smaller than this

Controls the minimum size file within the scope of an rclone command. Default units are KiB but abbreviations K, M, G, T or P are valid.

E.g. rclone ls remote: --min-size 50k lists files on remote: of 50 KiB size or larger.

See the size option docs for more info.

--max-size - Don't transfer any file larger than this

Controls the maximum size file within the scope of an rclone command. Default units are KiB but abbreviations K, M, G, T or P are valid.

E.g. rclone ls remote: --max-size 1G lists files on remote: of 1 GiB size or smaller.

See the size option docs for more info.

--max-age - Don't transfer any file older than this

Controls the maximum age of files within the scope of an rclone command.

--max-age applies only to files and not to directories.

E.g. rclone ls remote: --max-age 2d lists files on remote: of 2 days old or less.

See the time option docs for valid formats.

--min-age - Don't transfer any file younger than this

Controls the minimum age of files within the scope of an rclone command. (see --max-age for valid formats)

--min-age applies only to files and not to directories.

E.g. rclone ls remote: --min-age 2d lists files on remote: of 2 days old or more.

See the time option docs for valid formats.

Other flags

--delete-excluded - Delete files on dest excluded from sync

Important this flag is dangerous to your data - use with --dry-run and -v first.

In conjunction with rclone sync, --delete-excluded deletes any files on the destination which are excluded from the command.

E.g. the scope of rclone sync --interactive A: B: can be restricted:

rclone --min-size 50k --delete-excluded sync A: B:

All files on B: which are less than 50 KiB are deleted because they are excluded from the rclone sync command.

--dump filters - dump the filters to the output

Dumps the defined filters to standard output in regular expression format.

Useful for debugging.

Exclude directory based on a file

The --exclude-if-present flag controls whether a directory is within the scope of an rclone command based on the presence of a named file within it. The flag can be repeated to check for multiple file names, presence of any of them will exclude the directory.

This flag has a priority over other filter flags.

E.g. for the following directory structure:

dir1/file1
dir1/dir2/file2
dir1/dir2/dir3/file3
dir1/dir2/dir3/.ignore

The command rclone ls --exclude-if-present .ignore dir1 does not list dir3, file3 or .ignore.

Metadata filters

The metadata filters work in a very similar way to the normal file name filters, except they match metadata on the object.

The metadata should be specified as key=value patterns. This may be wildcarded using the normal filter patterns or regular expressions.

For example if you wished to list only local files with a mode of 100664 you could do that with:

rclone lsf -M --files-only --metadata-include "mode=100664" .

Or if you wished to show files with an atime, mtime or btime at a given date:

rclone lsf -M --files-only --metadata-include "[abm]time=2022-12-16*" .

Like file filtering, metadata filtering only applies to files not to directories.

The filters can be applied using these flags.

Each flag can be repeated. See the section on how filter rules are applied for more details - these flags work in an identical way to the file name filtering flags, but instead of file name patterns have metadata patterns.

Common pitfalls

The most frequent filter support issues on the rclone forum are:

GUI (Experimental)

Rclone can serve a web based GUI (graphical user interface). This is somewhat experimental at the moment so things may be subject to change.

Run this command in a terminal and rclone will download and then display the GUI in a web browser.

rclone rcd --rc-web-gui

This will produce logs like this and rclone needs to continue to run to serve the GUI:

2019/08/25 11:40:14 NOTICE: A new release for gui is present at https://github.com/rclone/rclone-webui-react/releases/download/v0.0.6/currentbuild.zip
2019/08/25 11:40:14 NOTICE: Downloading webgui binary. Please wait. [Size: 3813937, Path :  /home/USER/.cache/rclone/webgui/v0.0.6.zip]
2019/08/25 11:40:16 NOTICE: Unzipping
2019/08/25 11:40:16 NOTICE: Serving remote control on http://127.0.0.1:5572/

This assumes you are running rclone locally on your machine. It is possible to separate the rclone and the GUI - see below for details.

If you wish to check for updates then you can add --rc-web-gui-update to the command line.

If you find your GUI broken, you may force it to update by add --rc-web-gui-force-update.

By default, rclone will open your browser. Add --rc-web-gui-no-open-browser to disable this feature.

Using the GUI

Once the GUI opens, you will be looking at the dashboard which has an overall overview.

On the left hand side you will see a series of view buttons you can click on:

(More docs and walkthrough video to come!)

How it works

When you run the rclone rcd --rc-web-gui this is what happens

Advanced use

The rclone rcd may use any of the flags documented on the rc page.

The flag --rc-web-gui is shorthand for

These flags can be overridden as desired.

See also the rclone rcd documentation.

Example: Running a public GUI

For example the GUI could be served on a public port over SSL using an htpasswd file using the following flags:

Example: Running a GUI behind a proxy

If you want to run the GUI behind a proxy at /rclone you could use these flags:

Or instead of htpasswd if you just want a single user and password:

Project

The GUI is being developed in the: rclone/rclone-webui-react repository.

Bug reports and contributions are very welcome :-)

If you have questions then please ask them on the rclone forum.

Remote controlling rclone with its API

If rclone is run with the --rc flag then it starts an HTTP server which can be used to remote control rclone using its API.

You can either use the rc command to access the API or use HTTP directly.

If you just want to run a remote control then see the rcd command.

Supported parameters

--rc

Flag to start the http server listen on remote requests

--rc-addr=IP

IPaddress:Port or :Port to bind server to. (default "localhost:5572")

--rc-cert=KEY

SSL PEM key (concatenation of certificate and CA certificate)

--rc-client-ca=PATH

Client certificate authority to verify clients with

--rc-htpasswd=PATH

htpasswd file - if not provided no authentication is done

--rc-key=PATH

SSL PEM Private key

--rc-max-header-bytes=VALUE

Maximum size of request header (default 4096)

--rc-min-tls-version=VALUE

The minimum TLS version that is acceptable. Valid values are "tls1.0", "tls1.1", "tls1.2" and "tls1.3" (default "tls1.0").

--rc-user=VALUE

User name for authentication.

--rc-pass=VALUE

Password for authentication.

--rc-realm=VALUE

Realm for authentication (default "rclone")

--rc-server-read-timeout=DURATION

Timeout for server reading data (default 1h0m0s)

--rc-server-write-timeout=DURATION

Timeout for server writing data (default 1h0m0s)

--rc-serve

Enable the serving of remote objects via the HTTP interface. This means objects will be accessible at http://127.0.0.1:5572/ by default, so you can browse to http://127.0.0.1:5572/ or http://127.0.0.1:5572/* to see a listing of the remotes. Objects may be requested from remotes using this syntax http://127.0.0.1:5572/[remote:path]/path/to/object

Default Off.

--rc-files /path/to/directory

Path to local files to serve on the HTTP server.

If this is set then rclone will serve the files in that directory. It will also open the root in the web browser if specified. This is for implementing browser based GUIs for rclone functions.

If --rc-user or --rc-pass is set then the URL that is opened will have the authorization in the URL in the http://user:pass@localhost/ style.

Default Off.

--rc-enable-metrics

Enable OpenMetrics/Prometheus compatible endpoint at /metrics.

Default Off.

--rc-web-gui

Set this flag to serve the default web gui on the same port as rclone.

Default Off.

--rc-allow-origin

Set the allowed Access-Control-Allow-Origin for rc requests.

Can be used with --rc-web-gui if the rclone is running on different IP than the web-gui.

Default is IP address on which rc is running.

--rc-web-fetch-url

Set the URL to fetch the rclone-web-gui files from.

Default https://api.github.com/repos/rclone/rclone-webui-react/releases/latest.

--rc-web-gui-update

Set this flag to check and update rclone-webui-react from the rc-web-fetch-url.

Default Off.

--rc-web-gui-force-update

Set this flag to force update rclone-webui-react from the rc-web-fetch-url.

Default Off.

--rc-web-gui-no-open-browser

Set this flag to disable opening browser automatically when using web-gui.

Default Off.

--rc-job-expire-duration=DURATION

Expire finished async jobs older than DURATION (default 60s).

--rc-job-expire-interval=DURATION

Interval duration to check for expired async jobs (default 10s).

--rc-no-auth

By default rclone will require authorisation to have been set up on the rc interface in order to use any methods which access any rclone remotes. Eg operations/list is denied as it involved creating a remote as is sync/copy.

If this is set then no authorisation will be required on the server to use these methods. The alternative is to use --rc-user and --rc-pass and use these credentials in the request.

Default Off.

--rc-baseurl

Prefix for URLs.

Default is root

--rc-template

User-specified template.

Accessing the remote control via the rclone rc command

Rclone itself implements the remote control protocol in its rclone rc command.

You can use it like this

$ rclone rc rc/noop param1=one param2=two
{
    "param1": "one",
    "param2": "two"
}

Run rclone rc on its own to see the help for the installed remote control commands.

JSON input

rclone rc also supports a --json flag which can be used to send more complicated input parameters.

$ rclone rc --json '{ "p1": [1,"2",null,4], "p2": { "a":1, "b":2 } }' rc/noop
{
    "p1": [
        1,
        "2",
        null,
        4
    ],
    "p2": {
        "a": 1,
        "b": 2
    }
}

If the parameter being passed is an object then it can be passed as a JSON string rather than using the --json flag which simplifies the command line.

rclone rc operations/list fs=/tmp remote=test opt='{"showHash": true}'

Rather than

rclone rc operations/list --json '{"fs": "/tmp", "remote": "test", "opt": {"showHash": true}}'

Special parameters

The rc interface supports some special parameters which apply to all commands. These start with _ to show they are different.

Running asynchronous jobs with _async = true

Each rc call is classified as a job and it is assigned its own id. By default jobs are executed immediately as they are created or synchronously.

If _async has a true value when supplied to an rc call then it will return immediately with a job id and the task will be run in the background. The job/status call can be used to get information of the background job. The job can be queried for up to 1 minute after it has finished.

It is recommended that potentially long running jobs, e.g. sync/sync, sync/copy, sync/move, operations/purge are run with the _async flag to avoid any potential problems with the HTTP request and response timing out.

Starting a job with the _async flag:

$ rclone rc --json '{ "p1": [1,"2",null,4], "p2": { "a":1, "b":2 }, "_async": true }' rc/noop
{
    "jobid": 2
}

Query the status to see if the job has finished. For more information on the meaning of these return parameters see the job/status call.

$ rclone rc --json '{ "jobid":2 }' job/status
{
    "duration": 0.000124163,
    "endTime": "2018-10-27T11:38:07.911245881+01:00",
    "error": "",
    "finished": true,
    "id": 2,
    "output": {
        "_async": true,
        "p1": [
            1,
            "2",
            null,
            4
        ],
        "p2": {
            "a": 1,
            "b": 2
        }
    },
    "startTime": "2018-10-27T11:38:07.911121728+01:00",
    "success": true
}

job/list can be used to show the running or recently completed jobs

$ rclone rc job/list
{
    "jobids": [
        2
    ]
}

Setting config flags with _config

If you wish to set config (the equivalent of the global flags) for the duration of an rc call only then pass in the _config parameter.

This should be in the same format as the config key returned by options/get.

For example, if you wished to run a sync with the --checksum parameter, you would pass this parameter in your JSON blob.

"_config":{"CheckSum": true}

If using rclone rc this could be passed as

rclone rc sync/sync ... _config='{"CheckSum": true}'

Any config parameters you don't set will inherit the global defaults which were set with command line flags or environment variables.

Note that it is possible to set some values as strings or integers - see data types for more info. Here is an example setting the equivalent of --buffer-size in string or integer format.

"_config":{"BufferSize": "42M"}
"_config":{"BufferSize": 44040192}

If you wish to check the _config assignment has worked properly then calling options/local will show what the value got set to.

Setting filter flags with _filter

If you wish to set filters for the duration of an rc call only then pass in the _filter parameter.

This should be in the same format as the filter key returned by options/get.

For example, if you wished to run a sync with these flags

--max-size 1M --max-age 42s --include "a" --include "b"

you would pass this parameter in your JSON blob.

"_filter":{"MaxSize":"1M", "IncludeRule":["a","b"], "MaxAge":"42s"}

If using rclone rc this could be passed as

rclone rc ... _filter='{"MaxSize":"1M", "IncludeRule":["a","b"], "MaxAge":"42s"}'

Any filter parameters you don't set will inherit the global defaults which were set with command line flags or environment variables.

Note that it is possible to set some values as strings or integers - see data types for more info. Here is an example setting the equivalent of --buffer-size in string or integer format.

"_filter":{"MinSize": "42M"}
"_filter":{"MinSize": 44040192}

If you wish to check the _filter assignment has worked properly then calling options/local will show what the value got set to.

Assigning operations to groups with _group = value

Each rc call has its own stats group for tracking its metrics. By default grouping is done by the composite group name from prefix job/ and id of the job like so job/1.

If _group has a value then stats for that request will be grouped under that value. This allows caller to group stats under their own name.

Stats for specific group can be accessed by passing group to core/stats:

$ rclone rc --json '{ "group": "job/1" }' core/stats
{
    "speed": 12345
    ...
}

Data types

When the API returns types, these will mostly be straight forward integer, string or boolean types.

However some of the types returned by the options/get call and taken by the options/set calls as well as the vfsOpt, mountOpt and the _config parameters.

Specifying remotes to work on

Remotes are specified with the fs=, srcFs=, dstFs= parameters depending on the command being used.

The parameters can be a string as per the rest of rclone, eg s3:bucket/path or :sftp:/my/dir. They can also be specified as JSON blobs.

If specifying a JSON blob it should be a object mapping strings to strings. These values will be used to configure the remote. There are 3 special values which may be set:

One of _name or type should normally be set. If the local backend is desired then type should be set to local. If _root isn't specified then it defaults to the root of the remote.

For example this JSON is equivalent to remote:/tmp

{
    "_name": "remote",
    "_path": "/tmp"
}

And this is equivalent to :sftp,host='example.com':/tmp

{
    "type": "sftp",
    "host": "example.com",
    "_path": "/tmp"
}

And this is equivalent to /tmp/dir

{
    type = "local",
    _ path = "/tmp/dir"
}

Supported commands

backend/command: Runs a backend command.

This takes the following parameters:

Returns:

Example:

rclone rc backend/command command=noop fs=. -o echo=yes -o blue -a path1 -a path2

Returns

{
    "result": {
        "arg": [
            "path1",
            "path2"
        ],
        "name": "noop",
        "opt": {
            "blue": "",
            "echo": "yes"
        }
    }
}

Note that this is the direct equivalent of using this "backend" command:

rclone backend noop . -o echo=yes -o blue path1 path2

Note that arguments must be preceded by the "-a" flag

See the backend command for more information.

Authentication is required for this call.

cache/expire: Purge a remote from cache

Purge a remote from the cache backend. Supports either a directory or a file. Params: - remote = path to remote (required) - withData = true/false to delete cached data (chunks) as well (optional)

Eg

rclone rc cache/expire remote=path/to/sub/folder/
rclone rc cache/expire remote=/ withData=true

cache/fetch: Fetch file chunks

Ensure the specified file chunks are cached on disk.

The chunks= parameter specifies the file chunks to check. It takes a comma separated list of array slice indices. The slice indices are similar to Python slices: start[:end]

start is the 0 based chunk number from the beginning of the file to fetch inclusive. end is 0 based chunk number from the beginning of the file to fetch exclusive. Both values can be negative, in which case they count from the back of the file. The value "-5:" represents the last 5 chunks of a file.

Some valid examples are: ":5,-5:" -> the first and last five chunks "0,-2" -> the first and the second last chunk "0:10" -> the first ten chunks

Any parameter with a key that starts with "file" can be used to specify files to fetch, e.g.

rclone rc cache/fetch chunks=0 file=hello file2=home/goodbye

File names will automatically be encrypted when the a crypt remote is used on top of the cache.

cache/stats: Get cache stats

Show statistics for the cache remote.

See the config dump command for more information on the above.

Authentication is required for this call.

config/get: Get a remote in the config file.

Parameters:

See the config dump command for more information on the above.

Authentication is required for this call.

config/listremotes: Lists the remotes in the config file and defined in environment variables.

This takes the following parameters:

See the config update command for more information on the above.

Authentication is required for this call.

core/bwlimit: Set the bandwidth limit.

This sets the bandwidth limit to the string passed in. This should be a single bandwidth limit entry or a pair of upload:download bandwidth.

Eg

rclone rc core/bwlimit rate=off
{
    "bytesPerSecond": -1,
    "bytesPerSecondTx": -1,
    "bytesPerSecondRx": -1,
    "rate": "off"
}
rclone rc core/bwlimit rate=1M
{
    "bytesPerSecond": 1048576,
    "bytesPerSecondTx": 1048576,
    "bytesPerSecondRx": 1048576,
    "rate": "1M"
}
rclone rc core/bwlimit rate=1M:100k

}

If the rate parameter is not supplied then the bandwidth is queried

rclone rc core/bwlimit
{
    "bytesPerSecond": 1048576,
    "bytesPerSecondTx": 1048576,
    "bytesPerSecondRx": 1048576,
    "rate": "1M"
}

The format of the parameter is exactly the same as passed to --bwlimit except only one bandwidth may be specified.

In either case "rate" is returned as a human-readable string, and "bytesPerSecond" is returned as a number.

core/command: Run a rclone terminal command over rc.

This takes the following parameters:

Returns:

Example:

rclone rc core/command command=ls -a mydrive:/ -o max-depth=1
rclone rc core/command -a ls -a mydrive:/ -o max-depth=1

Returns:

{
    "error": false,
    "result": "<Raw command line output>"
}

OR
{
    "error": true,
    "result": "<Raw command line output>"
}

Authentication is required for this call.

core/du: Returns disk usage of a locally attached disk.

This returns the disk usage for the local directory passed in as dir.

If the directory is not passed in, it defaults to the directory pointed to by --cache-dir.

Returns:

            ...
        ]
}

core/memstats: Returns the memory statistics

This returns the memory statistics of the running program. What the values mean are explained in the go docs: https://golang.org/pkg/runtime/#MemStats

The most interesting values for most people are:

core/obscure: Obscures a string passed in.

Pass a clear string and rclone will obscure it for the config file: - clear - string

Returns: - obscured - string

}

core/version: Shows the current version of rclone and the go runtime.

This shows the current version of go and the go runtime:

debug/set-block-profile-rate: Set runtime.SetBlockProfileRate for blocking profiling.

SetBlockProfileRate controls the fraction of goroutine blocking events that are reported in the blocking profile. The profiler aims to sample an average of one blocking event per rate nanoseconds spent blocked.

To include every blocking event in the profile, pass rate = 1. To turn off profiling entirely, pass rate <= 0.

After calling this you can use this to see the blocking profile:

go tool pprof http://localhost:5572/debug/pprof/block

Parameters:

debug/set-gc-percent: Call runtime/debug.SetGCPercent for setting the garbage collection target percentage.

SetGCPercent sets the garbage collection target percentage: a collection is triggered when the ratio of freshly allocated data to live data remaining after the previous collection reaches this percentage. SetGCPercent returns the previous setting. The initial setting is the value of the GOGC environment variable at startup, or 100 if the variable is not set.

This setting may be effectively reduced in order to maintain a memory limit. A negative percentage effectively disables garbage collection, unless the memory limit is reached.

See https://pkg.go.dev/runtime/debug#SetMemoryLimit for more details.

Parameters:

debug/set-mutex-profile-fraction: Set runtime.SetMutexProfileFraction for mutex profiling.

SetMutexProfileFraction controls the fraction of mutex contention events that are reported in the mutex profile. On average 1/rate events are reported. The previous rate is returned.

To turn off profiling entirely, pass rate 0. To just read the current rate, pass rate < 0. (For n>1 the details of sampling may change.)

Once this is set you can look use this to profile the mutex contention:

go tool pprof http://localhost:5572/debug/pprof/mutex

Parameters:

Results:

debug/set-soft-memory-limit: Call runtime/debug.SetMemoryLimit for setting a soft memory limit for the runtime.

SetMemoryLimit provides the runtime with a soft memory limit.

The runtime undertakes several processes to try to respect this memory limit, including adjustments to the frequency of garbage collections and returning memory to the underlying system more aggressively. This limit will be respected even if GOGC=off (or, if SetGCPercent(-1) is executed).

The input limit is provided as bytes, and includes all memory mapped, managed, and not released by the Go runtime. Notably, it does not account for space used by the Go binary and memory external to Go, such as memory managed by the underlying system on behalf of the process, or memory managed by non-Go code inside the same process. Examples of excluded memory sources include: OS kernel memory held on behalf of the process, memory allocated by C code, and memory mapped by syscall.Mmap (because it is not managed by the Go runtime).

A zero limit or a limit that's lower than the amount of memory used by the Go runtime may cause the garbage collector to run nearly continuously. However, the application may still make progress.

The memory limit is always respected by the Go runtime, so to effectively disable this behavior, set the limit very high. math.MaxInt64 is the canonical value for disabling the limit, but values much greater than the available memory on the underlying system work just as well.

See https://go.dev/doc/gc-guide for a detailed guide explaining the soft memory limit in more detail, as well as a variety of common use-cases and scenarios.

SetMemoryLimit returns the previously set memory limit. A negative input does not adjust the limit, and allows for retrieval of the currently set memory limit.

Parameters:

fscache/clear: Clear the Fs cache.

This clears the fs cache. This is where remotes created from backends are cached for a short while to make repeated rc calls more efficient.

operations/uploadfile: Upload file using multiform/form-data

This takes the following parameters:

See the uploadfile command for more information on the above.

Authentication is required for this call.

options/blocks: List all the option blocks

Returns: - options - a list of the options block names

options/get: Get all the global options

Returns an object where keys are option block names and values are an object with the current option values in.

Note that these are the global options which are unaffected by use of the _config and _filter parameters. If you wish to read the parameters set in _config then use options/config and for _filter use options/filter.

This shows the internal names of the option within rclone which should map to the external options very easily with a few exceptions.

options/local: Get the currently active config for this call

Returns an object with the keys "config" and "filter". The "config" key contains the local config and the "filter" key contains the local filters.

Note that these are the local options specific to this rc call. If _config was not supplied then they will be the global options. Likewise with "_filter".

This call is mostly useful for seeing if _config and _filter passing is working.

This shows the internal names of the option within rclone which should map to the external options very easily with a few exceptions.

options/set: Set an option

Parameters:

Repeated as often as required.

Only supply the options you wish to change. If an option is unknown it will be silently ignored. Not all options will have an effect when changed like this.

For example:

This sets DEBUG level logs (-vv) (these can be set by number or string)

rclone rc options/set --json '{"main": {"LogLevel": "DEBUG"}}'
rclone rc options/set --json '{"main": {"LogLevel": 8}}'

And this sets INFO level logs (-v)

rclone rc options/set --json '{"main": {"LogLevel": "INFO"}}'

And this sets NOTICE level logs (normal without -v)

rclone rc options/set --json '{"main": {"LogLevel": "NOTICE"}}'

Authentication is required for this call.

rc/error: This returns an error

This returns an error with the input as part of its error string. Useful for testing error handling.

rc/list: List all the registered remote control commands

This lists all the registered remote control commands as a JSON map in the commands response.

rc/noop: Echo the input to the output parameters

This echoes the input parameters to the output parameters for testing purposes. It can be used to check that rclone is still alive and to check that parameter passing is working properly.

rc/noopauth: Echo the input to the output parameters requiring auth

This echoes the input parameters to the output parameters for testing purposes. It can be used to check that rclone is still alive and to check that parameter passing is working properly.

Authentication is required for this call.

sync/bisync: Perform bidirectional synchronization between two paths.

This takes the following parameters

See bisync command help and full bisync description for more information.

sync/move: move a directory from source remote to destination remote

This takes the following parameters:

See the move command for more information on the above.

Authentication is required for this call.

sync/sync: sync a directory from source remote to destination remote

This takes the following parameters:

See the sync command for more information on the above.

Authentication is required for this call.

vfs/forget: Forget files or directories in the directory cache.

This forgets the paths in the directory cache causing them to be re-read from the remote when needed.

If no paths are passed in then it will forget all the paths in the directory cache.

rclone rc vfs/forget

Otherwise pass files or dirs in as file=path or dir=path. Any parameter key starting with file will forget that file and any starting with dir will forget that dir, e.g.

rclone rc vfs/forget file=hello file2=goodbye dir=home/junk

This command takes an "fs" parameter. If this parameter is not supplied and if there is only one VFS in use then that VFS will be used. If there is more than one VFS in use then the "fs" parameter must be supplied.

vfs/list: List active VFSes.

This lists the active VFSes.

It returns a list under the key "vfses" where the values are the VFS names that could be passed to the other VFS commands in the "fs" parameter.

vfs/poll-interval: Get the status or update the value of the poll-interval option.

Without any parameter given this returns the current status of the poll-interval setting.

When the interval=duration parameter is set, the poll-interval value is updated and the polling function is notified. Setting interval=0 disables poll-interval.

rclone rc vfs/poll-interval interval=5m

The timeout=duration parameter can be used to specify a time to wait for the current poll function to apply the new value. If timeout is less or equal 0, which is the default, wait indefinitely.

The new poll-interval value will only be active when the timeout is not reached.

If poll-interval is updated or disabled temporarily, some changes might not get picked up by the polling function, depending on the used remote.

This command takes an "fs" parameter. If this parameter is not supplied and if there is only one VFS in use then that VFS will be used. If there is more than one VFS in use then the "fs" parameter must be supplied.

vfs/refresh: Refresh the directory cache.

This reads the directories for the specified paths and freshens the directory cache.

If no paths are passed in then it will refresh the root directory.

rclone rc vfs/refresh

Otherwise pass directories in as dir=path. Any parameter key starting with dir will refresh that directory, e.g.

rclone rc vfs/refresh dir=home/junk dir2=data/misc

If the parameter recursive=true is given the whole directory tree will get refreshed. This refresh will use --fast-list if enabled.

This command takes an "fs" parameter. If this parameter is not supplied and if there is only one VFS in use then that VFS will be used. If there is more than one VFS in use then the "fs" parameter must be supplied.

vfs/stats: Stats for a VFS.

This returns stats for the selected VFS.

{
    // Status of the disk cache - only present if --vfs-cache-mode > off
    "diskCache": {
        "bytesUsed": 0,
        "erroredFiles": 0,

        "hashType": 1,
        "outOfSpace": false,
        "path": "/home/user/.cache/rclone/vfs/local/mnt/a",
        "pathMeta": "/home/user/.cache/rclone/vfsMeta/local/mnt/a",
        "uploadsInProgress": 0,
        "uploadsQueued": 0
    },
    "fs": "/mnt/a",
    "inUse": 1,
    // Status of the in memory metadata cache
    "metadataCache": {
        "dirs": 1,
        "files": 0
    },
    // Options as returned by options/get
    "opt": {
        "CacheMaxAge": 3600000000000,
        // ...
        "WriteWait": 1000000000
    }
}

This command takes an "fs" parameter. If this parameter is not supplied and if there is only one VFS in use then that VFS will be used. If there is more than one VFS in use then the "fs" parameter must be supplied.

Accessing the remote control via HTTP

Rclone implements a simple HTTP based protocol.

Each endpoint takes an JSON object and returns a JSON object or an error. The JSON objects are essentially a map of string names to values.

All calls must made using POST.

The input objects can be supplied using URL parameters, POST parameters or by supplying "Content-Type: application/json" and a JSON blob in the body. There are examples of these below using curl.

The response will be a JSON blob in the body of the response. This is formatted to be reasonably human-readable.

Error returns

If an error occurs then there will be an HTTP error status (e.g. 500) and the body of the response will contain a JSON encoded error object, e.g.

{
    "error": "Expecting string value for key \"remote\" (was float64)",
    "input": {
        "fs": "/tmp",
        "remote": 3
    },
    "status": 400
    "path": "operations/rmdir",
}

The keys in the error response are - error - error string - input - the input parameters to the call - status - the HTTP status code - path - the path of the call

CORS

The sever implements basic CORS support and allows all origins for that. The response to a preflight OPTIONS request will echo the requested "Access-Control-Request-Headers" back.

Using POST with URL parameters only

curl -X POST 'http://localhost:5572/rc/noop?potato=1&sausage=2'

Response

{
    "potato": "1",
    "sausage": "2"
}

Here is what an error response looks like:

curl -X POST 'http://localhost:5572/rc/error?potato=1&sausage=2'
{
    "error": "arbitrary error on input map[potato:1 sausage:2]",
    "input": {
        "potato": "1",
        "sausage": "2"
    }
}

Note that curl doesn't return errors to the shell unless you use the -f option

$ curl -f -X POST 'http://localhost:5572/rc/error?potato=1&sausage=2'
curl: (22) The requested URL returned error: 400 Bad Request
$ echo $?
22

Using POST with a form

curl --data "potato=1" --data "sausage=2" http://localhost:5572/rc/noop

Response

{
    "potato": "1",
    "sausage": "2"
}

Note that you can combine these with URL parameters too with the POST parameters taking precedence.

curl --data "potato=1" --data "sausage=2" "http://localhost:5572/rc/noop?rutabaga=3&sausage=4"

Response

{
    "potato": "1",
    "rutabaga": "3",
    "sausage": "4"
}

Using POST with a JSON blob

curl -H "Content-Type: application/json" -X POST -d '{"potato":2,"sausage":1}' http://localhost:5572/rc/noop

response

{
    "password": "xyz",
    "username": "xyz"
}

This can be combined with URL parameters too if required. The JSON blob takes precedence.

curl -H "Content-Type: application/json" -X POST -d '{"potato":2,"sausage":1}' 'http://localhost:5572/rc/noop?rutabaga=3&potato=4'
{
    "potato": 2,
    "rutabaga": "3",
    "sausage": 1
}

Debugging rclone with pprof

If you use the --rc flag this will also enable the use of the go profiling tools on the same port.

To use these, first install go.

Debugging memory use

To profile rclone's memory use you can run:

go tool pprof -web http://localhost:5572/debug/pprof/heap

This should open a page in your browser showing what is using what memory.

You can also use the -text flag to produce a textual summary

$ go tool pprof -text http://localhost:5572/debug/pprof/heap

Debugging go routine leaks

Memory leaks are most often caused by go routine leaks keeping memory alive which should have been garbage collected.

See all active go routines using

curl http://localhost:5572/debug/pprof/goroutine?debug=1

Or go to http://localhost:5572/debug/pprof/goroutine?debug=1 in your browser.

Other profiles to look at

You can see a summary of profiles available at http://localhost:5572/debug/pprof/

Here is how to use some of them:

See the net/http/pprof docs for more info on how to use the profiling and for a general overview see the Go team's blog post on profiling go programs.

The profiling hook is zero overhead unless it is used.

Overview of cloud storage systems

Each cloud storage system is slightly different. Rclone attempts to provide a unified interface to them, but some underlying differences show through.

Notes

¹ Dropbox supports its own custom hash. This is an SHA256 sum of all the 4 MiB block SHA256s.

² SFTP supports checksums if the same login has shell access and md5sum or sha1sum as well as echo are in the remote's PATH.

³ WebDAV supports hashes when used with Fastmail Files, Owncloud and Nextcloud only.

⁴ WebDAV supports modtimes when used with Fastmail Files, Owncloud and Nextcloud only.

QuickXorHash is Microsoft's own hash.

⁶ Mail.ru uses its own modified SHA1 hash

⁷ pCloud only supports SHA1 (not MD5) in its EU region

⁸ Opendrive does not support creation of duplicate files using their web client interface or other stock clients, but the underlying storage platform has been determined to allow duplicate files, and it is possible to create them with rclone. It may be that this is a mistake or an unsupported feature.

⁹ QingStor does not support SetModTime for objects bigger than 5 GiB.

¹⁰ FTP supports modtimes for the major FTP servers, and also others if they advertised required protocol extensions. See this for more details.

¹¹ Internet Archive requires option wait_archive to be set to a non-zero value for full modtime support.

¹² HiDrive supports its own custom hash. It combines SHA1 sums for each 4 KiB block hierarchically to a single top-level sum.

Hash

The cloud storage system supports various hash types of the objects. The hashes are used when transferring data as an integrity check and can be specifically used with the --checksum flag in syncs and in the check command.

To use the verify checksums when transferring between cloud storage systems they must support a common hash type.

ModTime

Almost all cloud storage systems store some sort of timestamp on objects, but several of them not something that is appropriate to use for syncing. E.g. some backends will only write a timestamp that represent the time of the upload. To be relevant for syncing it should be able to store the modification time of the source object. If this is not the case, rclone will only check the file size by default, though can be configured to check the file hash (with the --checksum flag). Ideally it should also be possible to change the timestamp of an existing file without having to re-upload it.

Storage systems with a - in the ModTime column, means the modification read on objects is not the modification time of the file when uploaded. It is most likely the time the file was uploaded, or possibly something else (like the time the picture was taken in Google Photos).

Storage systems with a R (for read-only) in the ModTime column, means the it keeps modification times on objects, and updates them when uploading objects, but it does not support changing only the modification time (SetModTime operation) without re-uploading, possibly not even without deleting existing first. Some operations in rclone, such as copy and sync commands, will automatically check for SetModTime support and re-upload if necessary to keep the modification times in sync. Other commands will not work without SetModTime support, e.g. touch command on an existing file will fail, and changes to modification time only on a files in a mount will be silently ignored.

Storage systems with R/W (for read/write) in the ModTime column, means they do also support modtime-only operations.

Case Insensitive

If a cloud storage systems is case sensitive then it is possible to have two files which differ only in case, e.g. file.txt and FILE.txt. If a cloud storage system is case insensitive then that isn't possible.

This can cause problems when syncing between a case insensitive system and a case sensitive system. The symptom of this is that no matter how many times you run the sync it never completes fully.

The local filesystem and SFTP may or may not be case sensitive depending on OS.

Most of the time this doesn't cause any problems as people tend to avoid files whose name differs only by case even on case sensitive systems.

Duplicate files

If a cloud storage system allows duplicate files then it can have two objects with the same name.

This confuses rclone greatly when syncing - use the rclone dedupe command to rename or remove duplicates.

Restricted filenames

Some cloud storage systems might have restrictions on the characters that are usable in file or directory names. When rclone detects such a name during a file upload, it will transparently replace the restricted characters with similar looking Unicode characters. To handle the different sets of restricted characters for different backends, rclone uses something it calls encoding.

This process is designed to avoid ambiguous file names as much as possible and allow to move files between many cloud storage systems transparently.

The name shown by rclone to the user or during log output will only contain a minimal set of replaced characters to ensure correct formatting and not necessarily the actual name used on the cloud storage.

This transformation is reversed when downloading a file or parsing rclone arguments. For example, when uploading a file named my file?.txt to Onedrive, it will be displayed as my file?.txt on the console, but stored as my file?.txt to Onedrive (the ? gets replaced by the similar looking character, the so-called "fullwidth question mark"). The reverse transformation allows to read a file unusual/name.txt from Google Drive, by passing the name unusual/name.txt on the command line (the / needs to be replaced by the similar looking character).

Caveats

The filename encoding system works well in most cases, at least where file names are written in English or similar languages. You might not even notice it: It just works. In some cases it may lead to issues, though. E.g. when file names are written in Chinese, or Japanese, where it is always the Unicode fullwidth variants of the punctuation marks that are used.

On Windows, the characters :, * and ? are examples of restricted characters. If these are used in filenames on a remote that supports it, Rclone will transparently convert them to their fullwidth Unicode variants , and when downloading to Windows, and back again when uploading. This way files with names that are not allowed on Windows can still be stored.

However, if you have files on your Windows system originally with these same Unicode characters in their names, they will be included in the same conversion process. E.g. if you create a file in your Windows filesystem with name Test:1.jpg, where is the Unicode fullwidth colon symbol, and use rclone to upload it to Google Drive, which supports regular : (halfwidth question mark), rclone will replace the fullwidth : with the halfwidth : and store the file as Test:1.jpg in Google Drive. Since both Windows and Google Drive allows the name Test:1.jpg, it would probably be better if rclone just kept the name as is in this case.

With the opposite situation; if you have a file named Test:1.jpg, in your Google Drive, e.g. uploaded from a Linux system where : is valid in file names. Then later use rclone to copy this file to your Windows computer you will notice that on your local disk it gets renamed to Test:1.jpg. The original filename is not legal on Windows, due to the :, and rclone therefore renames it to make the copy possible. That is all good. However, this can also lead to an issue: If you already had a different file named Test:1.jpg on Windows, and then use rclone to copy either way. Rclone will then treat the file originally named Test:1.jpg on Google Drive and the file originally named Test:1.jpg on Windows as the same file, and replace the contents from one with the other.

Its virtually impossible to handle all cases like these correctly in all situations, but by customizing the encoding option, changing the set of characters that rclone should convert, you should be able to create a configuration that works well for your specific situation. See also the example below.

(Windows was used as an example of a file system with many restricted characters, and Google drive a storage system with few.)

Default restricted characters

The table below shows the characters that are replaced by default.

When a replacement character is found in a filename, this character will be escaped with the character to avoid ambiguous file names. (e.g. a file named ␀.txt would shown as ‛␀.txt)

Each cloud storage backend can use a different set of characters, which will be specified in the documentation for each backend.

SOH 0x01
STX 0x02
ETX 0x03

ESC 0x1B
FS 0x1C

The default encoding will also encode these file names as they are problematic with many cloud storage systems.

.. ..

Invalid UTF-8 bytes

Some backends only support a sequence of well formed UTF-8 bytes as file or directory names.

In this case all invalid UTF-8 bytes will be replaced with a quoted representation of the byte value to allow uploading a file to such a backend. For example, the invalid byte 0xFE will be encoded as ‛FE.

A common source of invalid UTF-8 bytes are local filesystems, that store names in a different encoding than UTF-8 or UTF-16, like latin1. See the local filenames section for details.

Encoding option

Most backends have an encoding option, specified as a flag --backend-encoding where backend is the name of the backend, or as a config parameter encoding (you'll need to select the Advanced config in rclone config to see it).

This will have default value which encodes and decodes characters in such a way as to preserve the maximum number of characters (see above).

However this can be incorrect in some scenarios, for example if you have a Windows file system with Unicode fullwidth characters , or , that you want to remain as those characters on the remote rather than being translated to regular (halfwidth) *, ? and :.

The --backend-encoding flags allow you to change that. You can disable the encoding completely with --backend-encoding None or set encoding = None in the config file.

Encoding takes a comma separated list of encodings. You can see the list of all possible values by passing an invalid value to this flag, e.g. --local-encoding "help". The command rclone help flags encoding will show you the defaults for the backends.

Encoding example: FTP

To take a specific example, the FTP backend's default encoding is

--ftp-encoding "Slash,Del,Ctl,RightSpace,Dot"

However, let's say the FTP server is running on Windows and can't have any of the invalid Windows characters in file names. You are backing up Linux servers to this FTP server which do have those characters in file names. So you would add the Windows set which are

Slash,LtGt,DoubleQuote,Colon,Question,Asterisk,Pipe,BackSlash,Ctl,RightSpace,RightPeriod,InvalidUtf8,Dot

to the existing ones, giving:

Slash,LtGt,DoubleQuote,Colon,Question,Asterisk,Pipe,BackSlash,Ctl,RightSpace,RightPeriod,InvalidUtf8,Dot,Del,RightSpace

This can be specified using the --ftp-encoding flag or using an encoding parameter in the config file.

Encoding example: Windows

As a nother example, take a Windows system where there is a file with name Test:1.jpg, where is the Unicode fullwidth colon symbol. When using rclone to copy this to a remote which supports :, the regular (halfwidth) colon (such as Google Drive), you will notice that the file gets renamed to Test:1.jpg.

To avoid this you can change the set of characters rclone should convert for the local filesystem, using command-line argument --local-encoding. Rclone's default behavior on Windows corresponds to

--local-encoding "Slash,LtGt,DoubleQuote,Colon,Question,Asterisk,Pipe,BackSlash,Ctl,RightSpace,RightPeriod,InvalidUtf8,Dot"

If you want to use fullwidth characters , and in your filenames without rclone changing them when uploading to a remote, then set the same as the default value but without Colon,Question,Asterisk:

--local-encoding "Slash,LtGt,DoubleQuote,Pipe,BackSlash,Ctl,RightSpace,RightPeriod,InvalidUtf8,Dot"

Alternatively, you can disable the conversion of any characters with --local-encoding None.

Instead of using command-line argument --local-encoding, you may also set it as environment variable RCLONE_LOCAL_ENCODING, or configure a remote of type local in your config, and set the encoding option there.

The risk by doing this is that if you have a filename with the regular (halfwidth) :, * and ? in your cloud storage, and you try to download it to your Windows filesystem, this will fail. These characters are not valid in filenames on Windows, and you have told rclone not to work around this by converting them to valid fullwidth variants.

MIME Type

MIME types (also known as media types) classify types of documents using a simple text classification, e.g. text/html or application/pdf.

Some cloud storage systems support reading (R) the MIME type of objects and some support writing (W) the MIME type of objects.

The MIME type can be important if you are serving files directly to HTTP from the storage system.

If you are copying from a remote which supports reading (R) to a remote which supports writing (W) then rclone will preserve the MIME types. Otherwise they will be guessed from the extension, or the remote itself may assign the MIME type.

Metadata

Backends may or may support reading or writing metadata. They may support reading and writing system metadata (metadata intrinsic to that backend) and/or user metadata (general purpose metadata).

The levels of metadata support are

Key Explanation
R Read only System Metadata
RW Read and write System Metadata
RWU Read and write System Metadata and read and write User Metadata

See the metadata docs for more info.

Optional Features

All rclone remotes support a base command set. Other features depend upon backend-specific capabilities.

Purge

This deletes a directory quicker than just deleting all the files in the directory.

† Note Swift implements this in order to delete directory markers but they don't actually have a quicker way of deleting files other than deleting them individually.

☨ Storj implements this efficiently only for entire buckets. If purging a directory inside a bucket, files are deleted individually.

‡ StreamUpload is not supported with Nextcloud

Copy

Used when copying an object to and from the same remote. This known as a server-side copy so you can copy a file without downloading it and uploading it again. It is used if you use rclone copy or rclone move if the remote doesn't support Move directly.

If the server doesn't support Copy directly then for copy operations the file is downloaded then re-uploaded.

Move

Used when moving/renaming an object on the same remote. This is known as a server-side move of a file. This is used in rclone move if the server doesn't support DirMove.

If the server isn't capable of Move then rclone simulates it with Copy then delete. If the server doesn't support Copy then rclone will download the file and re-upload it.

DirMove

This is used to implement rclone move to move a directory if possible. If it isn't then it will use Move on each file (which falls back to Copy then download and upload - see Move section).

CleanUp

This is used for emptying the trash for a remote by rclone cleanup.

If the server can't do CleanUp then rclone cleanup will return an error.

‡‡ Note that while Box implements this it has to delete every file individually so it will be slower than emptying the trash via the WebUI

ListR

The remote supports a recursive list to list all the contents beneath a directory quickly. This enables the --fast-list flag to work. See the rclone docs for more details.

StreamUpload

Some remotes allow files to be uploaded without knowing the file size in advance. This allows certain operations to work without spooling the file to local disk first, e.g. rclone rcat.

MultithreadUpload

Some remotes allow transfers to the remote to be sent as chunks in parallel. If this is supported then rclone will use multi-thread copying to transfer files much faster.

LinkSharing

Sets the necessary permissions on a file or folder and prints a link that allows others to access them, even if they don't have an account on the particular cloud provider.

About

Rclone about prints quota information for a remote. Typical output includes bytes used, free, quota and in trash.

If a remote lacks about capability rclone about remote:returns an error.

Backends without about capability cannot determine free space for an rclone mount, or use policy mfs (most free space) as a member of an rclone union remote.

See rclone about command

EmptyDir

The remote supports empty directories. See Limitations for details. Most Object/Bucket-based remotes do not support this.

Docker Volume Plugin

Introduction

Docker 1.9 has added support for creating named volumes via command-line interface and mounting them in containers as a way to share data between them. Since Docker 1.10 you can create named volumes with Docker Compose by descriptions in docker-compose.yml files for use by container groups on a single host. As of Docker 1.12 volumes are supported by Docker Swarm included with Docker Engine and created from descriptions in swarm compose v3 files for use with swarm stacks across multiple cluster nodes.

Docker Volume Plugins augment the default local volume driver included in Docker with stateful volumes shared across containers and hosts. Unlike local volumes, your data will not be deleted when such volume is removed. Plugins can run managed by the docker daemon, as a native system service (under systemd, sysv or upstart) or as a standalone executable. Rclone can run as docker volume plugin in all these modes. It interacts with the local docker daemon via plugin API and handles mounting of remote file systems into docker containers so it must run on the same host as the docker daemon or on every Swarm node.

Getting started

In the first example we will use the SFTP rclone volume with Docker engine on a standalone Ubuntu machine.

Start from installing Docker on the host.

The FUSE driver is a prerequisite for rclone mounting and should be installed on host:

sudo apt-get -y install fuse

Create two directories required by rclone docker plugin:

sudo mkdir -p /var/lib/docker-plugins/rclone/config
sudo mkdir -p /var/lib/docker-plugins/rclone/cache

Install the managed rclone docker plugin for your architecture (here amd64):

docker plugin install rclone/docker-volume-rclone:amd64 args="-v" --alias rclone --grant-all-permissions
docker plugin list

Create your SFTP volume:

docker volume create firstvolume -d rclone -o type=sftp -o sftp-host=_hostname_ -o sftp-user=_username_ -o sftp-pass=_password_ -o allow-other=true

Note that since all options are static, you don't even have to run rclone config or create the rclone.conf file (but the config directory should still be present). In the simplest case you can use localhost as hostname and your SSH credentials as username and password. You can also change the remote path to your home directory on the host, for example -o path=/home/username.

Time to create a test container and mount the volume into it:

docker run --rm -it -v firstvolume:/mnt --workdir /mnt ubuntu:latest bash

If all goes well, you will enter the new container and change right to the mounted SFTP remote. You can type ls to list the mounted directory or otherwise play with it. Type exit when you are done. The container will stop but the volume will stay, ready to be reused. When it's not needed anymore, remove it:

docker volume list
docker volume remove firstvolume

Now let us try something more elaborate: Google Drive volume on multi-node Docker Swarm.

You should start from installing Docker and FUSE, creating plugin directories and installing rclone plugin on every swarm node. Then setup the Swarm.

Google Drive volumes need an access token which can be setup via web browser and will be periodically renewed by rclone. The managed plugin cannot run a browser so we will use a technique similar to the rclone setup on a headless box.

Run rclone config on another machine equipped with web browser and graphical user interface. Create the Google Drive remote. When done, transfer the resulting rclone.conf to the Swarm cluster and save as /var/lib/docker-plugins/rclone/config/rclone.conf on every node. By default this location is accessible only to the root user so you will need appropriate privileges. The resulting config will look like this:

[gdrive]
type = drive
scope = drive
drive_id = 1234567...
root_folder_id = 0Abcd...
token = {"access_token":...}

Now create the file named example.yml with a swarm stack description like this:

version: '3'
services:
  heimdall:
    image: linuxserver/heimdall:latest
    ports: [8080:80]
    volumes: [configdata:/config]
volumes:
  configdata:
    driver: rclone
    driver_opts:
      remote: 'gdrive:heimdall'
      allow_other: 'true'
      vfs_cache_mode: full
      poll_interval: 0

and run the stack:

docker stack deploy example -c ./example.yml

After a few seconds docker will spread the parsed stack description over cluster, create the example_heimdall service on port 8080, run service containers on one or more cluster nodes and request the example_configdata volume from rclone plugins on the node hosts. You can use the following commands to confirm results:

docker service ls
docker service ps example_heimdall
docker volume ls

Point your browser to http://cluster.host.address:8080 and play with the service. Stop it with docker stack remove example when you are done. Note that the example_configdata volume(s) created on demand at the cluster nodes will not be automatically removed together with the stack but stay for future reuse. You can remove them manually by invoking the docker volume remove example_configdata command on every node.

Creating Volumes via CLI

Volumes can be created with docker volume create. Here are a few examples:

docker volume create vol1 -d rclone -o remote=storj: -o vfs-cache-mode=full
docker volume create vol2 -d rclone -o remote=:storj,access_grant=xxx:heimdall
docker volume create vol3 -d rclone -o type=storj -o path=heimdall -o storj-access-grant=xxx -o poll-interval=0

Note the -d rclone flag that tells docker to request volume from the rclone driver. This works even if you installed managed driver by its full name rclone/docker-volume-rclone because you provided the --alias rclone option.

Volumes can be inspected as follows:

docker volume list
docker volume inspect vol1

Volume Configuration

Rclone flags and volume options are set via the -o flag to the docker volume create command. They include backend-specific parameters as well as mount and VFS options. Also there are a few special -o options: remote, fs, type, path, mount-type and persist.

remote determines an existing remote name from the config file, with trailing colon and optionally with a remote path. See the full syntax in the rclone documentation. This option can be aliased as fs to prevent confusion with the remote parameter of such backends as crypt or alias.

The remote=:backend:dir/subdir syntax can be used to create on-the-fly (config-less) remotes, while the type and path options provide a simpler alternative for this. Using two split options

-o type=backend -o path=dir/subdir

is equivalent to the combined syntax

-o remote=:backend:dir/subdir

but is arguably easier to parameterize in scripts. The path part is optional.

Mount and VFS options as well as backend parameters are named like their twin command-line flags without the -- CLI prefix. Optionally you can use underscores instead of dashes in option names. For example, --vfs-cache-mode full becomes -o vfs-cache-mode=full or -o vfs_cache_mode=full. Boolean CLI flags without value will gain the true value, e.g. --allow-other becomes -o allow-other=true or -o allow_other=true.

Please note that you can provide parameters only for the backend immediately referenced by the backend type of mounted remote. If this is a wrapping backend like alias, chunker or crypt, you cannot provide options for the referred to remote or backend. This limitation is imposed by the rclone connection string parser. The only workaround is to feed plugin with rclone.conf or configure plugin arguments (see below).

Special Volume Options

mount-type determines the mount method and in general can be one of: mount, cmount, or mount2. This can be aliased as mount_type. It should be noted that the managed rclone docker plugin currently does not support the cmount method and mount2 is rarely needed. This option defaults to the first found method, which is usually mount so you generally won't need it.

persist is a reserved boolean (true/false) option. In future it will allow to persist on-the-fly remotes in the plugin rclone.conf file.

Connection Strings

The remote value can be extended with connection strings as an alternative way to supply backend parameters. This is equivalent to the -o backend options with one syntactic difference. Inside connection string the backend prefix must be dropped from parameter names but in the -o param=value array it must be present. For instance, compare the following option array

-o remote=:sftp:/home -o sftp-host=localhost

with equivalent connection string:

-o remote=:sftp,host=localhost:/home

This difference exists because flag options -o key=val include not only backend parameters but also mount/VFS flags and possibly other settings. Also it allows to discriminate the remote option from the crypt-remote (or similarly named backend parameters) and arguably simplifies scripting due to clearer value substitution.

Using with Swarm or Compose

Both Docker Swarm and Docker Compose use YAML-formatted text files to describe groups (stacks) of containers, their properties, networks and volumes. Compose uses the compose v2 format, Swarm uses the compose v3 format. They are mostly similar, differences are explained in the docker documentation.

Volumes are described by the children of the top-level volumes: node. Each of them should be named after its volume and have at least two elements, the self-explanatory driver: rclone value and the driver_opts: structure playing the same role as -o key=val CLI flags:

volumes:
  volume_name_1:
    driver: rclone
    driver_opts:
      remote: 'gdrive:'
      allow_other: 'true'
      vfs_cache_mode: full
      token: '{"type": "borrower", "expires": "2021-12-31"}'
      poll_interval: 0

Notice a few important details: - YAML prefers _ in option names instead of -. - YAML treats single and double quotes interchangeably. Simple strings and integers can be left unquoted. - Boolean values must be quoted like 'true' or "false" because these two words are reserved by YAML. - The filesystem string is keyed with remote (or with fs). Normally you can omit quotes here, but if the string ends with colon, you must quote it like remote: "storage_box:". - YAML is picky about surrounding braces in values as this is in fact another syntax for key/value mappings. For example, JSON access tokens usually contain double quotes and surrounding braces, so you must put them in single quotes.

Installing as Managed Plugin

Docker daemon can install plugins from an image registry and run them managed. We maintain the docker-volume-rclone plugin image on Docker Hub.

Rclone volume plugin requires Docker Engine >= 19.03.15

The plugin requires presence of two directories on the host before it can be installed. Note that plugin will not create them automatically. By default they must exist on host at the following locations (though you can tweak the paths): - /var/lib/docker-plugins/rclone/config is reserved for the rclone.conf config file and must exist even if it's empty and the config file is not present. - /var/lib/docker-plugins/rclone/cache holds the plugin state file as well as optional VFS caches.

You can install managed plugin with default settings as follows:

docker plugin install rclone/docker-volume-rclone:amd64 --grant-all-permissions --alias rclone

The :amd64 part of the image specification after colon is called a tag. Usually you will want to install the latest plugin for your architecture. In this case the tag will just name it, like amd64 above. The following plugin architectures are currently available: - amd64 - arm64 - arm-v7

Sometimes you might want a concrete plugin version, not the latest one. Then you should use image tag in the form :ARCHITECTURE-VERSION. For example, to install plugin version v1.56.2 on architecture arm64 you will use tag arm64-1.56.2 (note the removed v) so the full image specification becomes rclone/docker-volume-rclone:arm64-1.56.2.

We also provide the latest plugin tag, but since docker does not support multi-architecture plugins as of the time of this writing, this tag is currently an alias for amd64. By convention the latest tag is the default one and can be omitted, thus both rclone/docker-volume-rclone:latest and just rclone/docker-volume-rclone will refer to the latest plugin release for the amd64 platform.

Also the amd64 part can be omitted from the versioned rclone plugin tags. For example, rclone image reference rclone/docker-volume-rclone:amd64-1.56.2 can be abbreviated as rclone/docker-volume-rclone:1.56.2 for convenience. However, for non-intel architectures you still have to use the full tag as amd64 or latest will fail to start.

Managed plugin is in fact a special container running in a namespace separate from normal docker containers. Inside it runs the rclone serve docker command. The config and cache directories are bind-mounted into the container at start. The docker daemon connects to a unix socket created by the command inside the container. The command creates on-demand remote mounts right inside, then docker machinery propagates them through kernel mount namespaces and bind-mounts into requesting user containers.

You can tweak a few plugin settings after installation when it's disabled (not in use), for instance:

docker plugin disable rclone
docker plugin set rclone RCLONE_VERBOSE=2 config=/etc/rclone args="--vfs-cache-mode=writes --allow-other"
docker plugin enable rclone
docker plugin inspect rclone

Note that if docker refuses to disable the plugin, you should find and remove all active volumes connected with it as well as containers and swarm services that use them. This is rather tedious so please carefully plan in advance.

You can tweak the following settings: args, config, cache, HTTP_PROXY, HTTPS_PROXY, NO_PROXY and RCLONE_VERBOSE. It's your task to keep plugin settings in sync across swarm cluster nodes.

args sets command-line arguments for the rclone serve docker command (none by default). Arguments should be separated by space so you will normally want to put them in quotes on the docker plugin set command line. Both serve docker flags and generic rclone flags are supported, including backend parameters that will be used as defaults for volume creation. Note that plugin will fail (due to this docker bug) if the args value is empty. Use e.g. args="-v" as a workaround.

config=/host/dir sets alternative host location for the config directory. Plugin will look for rclone.conf here. It's not an error if the config file is not present but the directory must exist. Please note that plugin can periodically rewrite the config file, for example when it renews storage access tokens. Keep this in mind and try to avoid races between the plugin and other instances of rclone on the host that might try to change the config simultaneously resulting in corrupted rclone.conf. You can also put stuff like private key files for SFTP remotes in this directory. Just note that it's bind-mounted inside the plugin container at the predefined path /data/config. For example, if your key file is named sftp-box1.key on the host, the corresponding volume config option should read -o sftp-key-file=/data/config/sftp-box1.key.

cache=/host/dir sets alternative host location for the cache directory. The plugin will keep VFS caches here. Also it will create and maintain the docker-plugin.state file in this directory. When the plugin is restarted or reinstalled, it will look in this file to recreate any volumes that existed previously. However, they will not be re-mounted into consuming containers after restart. Usually this is not a problem as the docker daemon normally will restart affected user containers after failures, daemon restarts or host reboots.

RCLONE_VERBOSE sets plugin verbosity from 0 (errors only, by default) to 2 (debugging). Verbosity can be also tweaked via args="-v [-v] ...". Since arguments are more generic, you will rarely need this setting. The plugin output by default feeds the docker daemon log on local host. Log entries are reflected as errors in the docker log but retain their actual level assigned by rclone in the encapsulated message string.

HTTP_PROXY, HTTPS_PROXY, NO_PROXY customize the plugin proxy settings.

You can set custom plugin options right when you install it, in one go:

docker plugin remove rclone
docker plugin install rclone/docker-volume-rclone:amd64 \
       --alias rclone --grant-all-permissions \
       args="-v --allow-other" config=/etc/rclone
docker plugin inspect rclone

Healthchecks

The docker plugin volume protocol doesn't provide a way for plugins to inform the docker daemon that a volume is (un-)available. As a workaround you can setup a healthcheck to verify that the mount is responding, for example:

services:
  my_service:
    image: my_image
    healthcheck:
      test: ls /path/to/rclone/mount || exit 1
      interval: 1m
      timeout: 15s
      retries: 3
      start_period: 15s

Running Plugin under Systemd

In most cases you should prefer managed mode. Moreover, MacOS and Windows do not support native Docker plugins. Please use managed mode on these systems. Proceed further only if you are on Linux.

First, install rclone. You can just run it (type rclone serve docker and hit enter) for the test.

Install FUSE:

sudo apt-get -y install fuse

Download two systemd configuration files: docker-volume-rclone.service and docker-volume-rclone.socket.

Put them to the /etc/systemd/system/ directory:

cp docker-volume-plugin.service /etc/systemd/system/
cp docker-volume-plugin.socket  /etc/systemd/system/

Please note that all commands in this section must be run as root but we omit sudo prefix for brevity. Now create directories required by the service:

mkdir -p /var/lib/docker-volumes/rclone
mkdir -p /var/lib/docker-plugins/rclone/config
mkdir -p /var/lib/docker-plugins/rclone/cache

Run the docker plugin service in the socket activated mode:

systemctl daemon-reload
systemctl start docker-volume-rclone.service
systemctl enable docker-volume-rclone.socket
systemctl start docker-volume-rclone.socket
systemctl restart docker

Or run the service directly: - run systemctl daemon-reload to let systemd pick up new config - run systemctl enable docker-volume-rclone.service to make the new service start automatically when you power on your machine. - run systemctl start docker-volume-rclone.service to start the service now. - run systemctl restart docker to restart docker daemon and let it detect the new plugin socket. Note that this step is not needed in managed mode where docker knows about plugin state changes.

The two methods are equivalent from the user perspective, but I personally prefer socket activation.

Troubleshooting

You can see managed plugin settings with

docker plugin list
docker plugin inspect rclone

Note that docker (including latest 20.10.7) will not show actual values of args, just the defaults.

Use journalctl --unit docker to see managed plugin output as part of the docker daemon log. Note that docker reflects plugin lines as errors but their actual level can be seen from encapsulated message string.

You will usually install the latest version of managed plugin for your platform. Use the following commands to print the actual installed version:

PLUGID=$(docker plugin list --no-trunc | awk '/rclone/{print$1}')
sudo runc --root /run/docker/runtime-runc/plugins.moby exec $PLUGID rclone version

You can even use runc to run shell inside the plugin container:

sudo runc --root /run/docker/runtime-runc/plugins.moby exec --tty $PLUGID bash

Also you can use curl to check the plugin socket connectivity:

docker plugin list --no-trunc
PLUGID=123abc...
sudo curl -H Content-Type:application/json -XPOST -d {} --unix-socket /run/docker/plugins/$PLUGID/rclone.sock http://localhost/Plugin.Activate

though this is rarely needed.

Caveats

Finally I'd like to mention a caveat with updating volume settings. Docker CLI does not have a dedicated command like docker volume update. It may be tempting to invoke docker volume create with updated options on existing volume, but there is a gotcha. The command will do nothing, it won't even return an error. I hope that docker maintainers will fix this some day. In the meantime be aware that you must remove your volume before recreating it with new settings:

docker volume remove my_vol
docker volume create my_vol -d rclone -o opt1=new_val1 ...

and verify that settings did update:

docker volume list
docker volume inspect my_vol

If docker refuses to remove the volume, you should find containers or swarm services that use it and stop them first.

Arbitrary rclone flags may be specified on the bisync command line, for example rclone bisync ./testdir/path1/ gdrive:testdir/path2/ --drive-skip-gdocs -v -v --timeout 10s Note that interactions of various rclone flags with bisync process flow has not been fully tested yet.

Paths

Path1 and Path2 arguments may be references to any mix of local directory paths (absolute or relative), UNC paths (//server/share/path), Windows drive paths (with a drive letter and :) or configured remotes with optional subdirectory paths. Cloud references are distinguished by having a : in the argument (see Windows support below).

Path1 and Path2 are treated equally, in that neither has priority for file changes (except during --resync), and access efficiency does not change whether a remote is on Path1 or Path2.

The listings in bisync working directory (default: ~/.cache/rclone/bisync) are named based on the Path1 and Path2 arguments so that separate syncs to individual directories within the tree may be set up, e.g.: path_to_local_tree..dropbox_subdir.lst.

Any empty directories after the sync on both the Path1 and Path2 filesystems are not deleted by default, unless --create-empty-src-dirs is specified. If the --remove-empty-dirs flag is specified, then both paths will have ALL empty directories purged as the last step in the process.

Command-line flags

--resync

This will effectively make both Path1 and Path2 filesystems contain a matching superset of all files. Path2 files that do not exist in Path1 will be copied to Path1, and the process will then copy the Path1 tree to Path2.

The --resync sequence is roughly equivalent to:

rclone copy Path2 Path1 --ignore-existing
rclone copy Path1 Path2

Or, if using --create-empty-src-dirs:

rclone copy Path2 Path1 --ignore-existing
rclone copy Path1 Path2 --create-empty-src-dirs
rclone copy Path2 Path1 --create-empty-src-dirs

The base directories on both Path1 and Path2 filesystems must exist or bisync will fail. This is required for safety - that bisync can verify that both paths are valid.

When using --resync, a newer version of a file on the Path2 filesystem will be overwritten by the Path1 filesystem version. (Note that this is NOT entirely symmetrical.) Carefully evaluate deltas using --dry-run.

For a resync run, one of the paths may be empty (no files in the path tree). The resync run should result in files on both paths, else a normal non-resync run will fail.

For a non-resync run, either path being empty (no files in the tree) fails with Empty current PathN listing. Cannot sync to an empty directory: X.pathN.lst This is a safety check that an unexpected empty path does not result in deleting everything in the other path.

--check-access

Access check files are an additional safety measure against data loss. bisync will ensure it can find matching RCLONE_TEST files in the same places in the Path1 and Path2 filesystems. RCLONE_TEST files are not generated automatically. For --check-access to succeed, you must first either: A) Place one or more RCLONE_TEST files in both systems, or B) Set --check-filename to a filename already in use in various locations throughout your sync'd fileset. Recommended methods for A) include: * rclone touch Path1/RCLONE_TEST (create a new file) * rclone copyto Path1/RCLONE_TEST Path2/RCLONE_TEST (copy an existing file) * rclone copy Path1/RCLONE_TEST Path2/RCLONE_TEST --include "RCLONE_TEST" (copy multiple files at once, recursively) * create the files manually (outside of rclone) * run bisync once without --check-access to set matching files on both filesystems will also work, but is not preferred, due to potential for user error (you are temporarily disabling the safety feature).

Note that --check-access is still enforced on --resync, so bisync --resync --check-access will not work as a method of initially setting the files (this is to ensure that bisync can't inadvertently circumvent its own safety switch.)

Time stamps and file contents for RCLONE_TEST files are not important, just the names and locations. If you have symbolic links in your sync tree it is recommended to place RCLONE_TEST files in the linked-to directory tree to protect against bisync assuming a bunch of deleted files if the linked-to tree should not be accessible. See also the --check-filename flag.

--check-filename

Name of the file(s) used in access health validation. The default --check-filename is RCLONE_TEST. One or more files having this filename must exist, synchronized between your source and destination filesets, in order for --check-access to succeed. See --check-access for additional details.

--max-delete

As a safety check, if greater than the --max-delete percent of files were deleted on either the Path1 or Path2 filesystem, then bisync will abort with a warning message, without making any changes. The default --max-delete is 50%. One way to trigger this limit is to rename a directory that contains more than half of your files. This will appear to bisync as a bunch of deleted files and a bunch of new files. This safety check is intended to block bisync from deleting all of the files on both filesystems due to a temporary network access issue, or if the user had inadvertently deleted the files on one side or the other. To force the sync, either set a different delete percentage limit, e.g. --max-delete 75 (allows up to 75% deletion), or use --force to bypass the check.

Also see the all files changed check.

--filters-file

By using rclone filter features you can exclude file types or directory sub-trees from the sync. See the bisync filters section and generic --filter-from documentation. An example filters file contains filters for non-allowed files for synching with Dropbox.

If you make changes to your filters file then bisync requires a run with --resync. This is a safety feature, which prevents existing files on the Path1 and/or Path2 side from seeming to disappear from view (since they are excluded in the new listings), which would fool bisync into seeing them as deleted (as compared to the prior run listings), and then bisync would proceed to delete them for real.

To block this from happening, bisync calculates an MD5 hash of the filters file and stores the hash in a .md5 file in the same place as your filters file. On the next run with --filters-file set, bisync re-calculates the MD5 hash of the current filters file and compares it to the hash stored in the .md5 file. If they don't match, the run aborts with a critical error and thus forces you to do a --resync, likely avoiding a disaster.

--check-sync

Enabled by default, the check-sync function checks that all of the same files exist in both the Path1 and Path2 history listings. This check-sync integrity check is performed at the end of the sync run by default. Any untrapped failing copy/deletes between the two paths might result in differences between the two listings and in the untracked file content differences between the two paths. A resync run would correct the error.

Note that the default-enabled integrity check locally executes a load of both the final Path1 and Path2 listings, and thus adds to the run time of a sync. Using --check-sync=false will disable it and may significantly reduce the sync run times for very large numbers of files.

The check may be run manually with --check-sync=only. It runs only the integrity check and terminates without actually synching.

See also: Concurrent modifications

--ignore-listing-checksum

By default, bisync will retrieve (or generate) checksums (for backends that support them) when creating the listings for both paths, and store the checksums in the listing files. --ignore-listing-checksum will disable this behavior, which may speed things up considerably, especially on backends (such as local) where hashes must be computed on the fly instead of retrieved. Please note the following:

--resilient

Caution: this is an experimental feature. Use at your own risk!

By default, most errors or interruptions will cause bisync to abort and require --resync to recover. This is a safety feature, to prevent bisync from running again until a user checks things out. However, in some cases, bisync can go too far and enforce a lockout when one isn't actually necessary, like for certain less-serious errors that might resolve themselves on the next run. When --resilient is specified, bisync tries its best to recover and self-correct, and only requires --resync as a last resort when a human's involvement is absolutely necessary. The intended use case is for running bisync as a background process (such as via scheduled cron).

When using --resilient mode, bisync will still report the error and abort, however it will not lock out future runs -- allowing the possibility of retrying at the next normally scheduled time, without requiring a --resync first. Examples of such retryable errors include access test failures, missing listing files, and filter change detections. These safety features will still prevent the current run from proceeding -- the difference is that if conditions have improved by the time of the next run, that next run will be allowed to proceed. Certain more serious errors will still enforce a --resync lockout, even in --resilient mode, to prevent data loss.

Behavior of --resilient may change in a future version.

As of rclone v1.64, bisync is now better at detecting false positive sync conflicts, which would previously have resulted in unnecessary renames and duplicates. Now, when bisync comes to a file that it wants to rename (because it is new/changed on both sides), it first checks whether the Path1 and Path2 versions are currently identical (using the same underlying function as check.) If bisync concludes that the files are identical, it will skip them and move on. Otherwise, it will create renamed ..Path1 and ..Path2 duplicates, as before. This behavior also improves the experience of renaming directories, as a --resync is no longer required, so long as the same change has been made on both sides.

All files changed check

If all prior existing files on either of the filesystems have changed (e.g. timestamps have changed due to changing the system's timezone) then bisync will abort without making any changes. Any new files are not considered for this check. You could use --force to force the sync (whichever side has the changed timestamp files wins). Alternately, a --resync may be used (Path1 versions will be pushed to Path2). Consider the situation carefully and perhaps use --dry-run before you commit to the changes.

Modification time

Bisync relies on file timestamps to identify changed files and will refuse to operate if backend lacks the modification time support.

If you or your application should change the content of a file without changing the modification time then bisync will not notice the change, and thus will not copy it to the other side.

Note that on some cloud storage systems it is not possible to have file timestamps that match precisely between the local and other filesystems.

Bisync's approach to this problem is by tracking the changes on each side separately over time with a local database of files in that side then applying the resulting changes on the other side.

Error handling

Certain bisync critical errors, such as file copy/move failing, will result in a bisync lockout of following runs. The lockout is asserted because the sync status and history of the Path1 and Path2 filesystems cannot be trusted, so it is safer to block any further changes until someone checks things out. The recovery is to do a --resync again.

It is recommended to use --resync --dry-run --verbose initially and carefully review what changes will be made before running the --resync without --dry-run.

Most of these events come up due to an error status from an internal call. On such a critical error the {...}.path1.lst and {...}.path2.lst listing files are renamed to extension .lst-err, which blocks any future bisync runs (since the normal .lst files are not found). Bisync keeps them under bisync subdirectory of the rclone cache directory, typically at ${HOME}/.cache/rclone/bisync/ on Linux.

Some errors are considered temporary and re-running the bisync is not blocked. The critical return blocks further bisync runs.

See also: --resilient

Lock file

When bisync is running, a lock file is created in the bisync working directory, typically at ~/.cache/rclone/bisync/PATH1..PATH2.lck on Linux. If bisync should crash or hang, the lock file will remain in place and block any further runs of bisync for the same paths. Delete the lock file as part of debugging the situation. The lock file effectively blocks follow-on (e.g., scheduled by cron) runs when the prior invocation is taking a long time. The lock file contains PID of the blocking process, which may help in debug.

Note that while concurrent bisync runs are allowed, be very cautious that there is no overlap in the trees being synched between concurrent runs, lest there be replicated files, deleted files and general mayhem.

Return codes

rclone bisync returns the following codes to calling program: - 0 on a successful run, - 1 for a non-critical failing run (a rerun may be successful), - 2 for a critically aborted run (requires a --resync to recover).

Limitations

Supported backends

Bisync is considered BETA and has been tested with the following backends: - Local filesystem - Google Drive - Dropbox - OneDrive - S3 - SFTP - Yandex Disk

It has not been fully tested with other services yet. If it works, or sorta works, please let us know and we'll update the list. Run the test suite to check for proper operation as described below.

First release of rclone bisync requires that underlying backend supports the modification time feature and will refuse to run otherwise. This limitation will be lifted in a future rclone bisync release.

Concurrent modifications

When using Local, FTP or SFTP remotes rclone does not create temporary files at the destination when copying, and thus if the connection is lost the created file may be corrupt, which will likely propagate back to the original path on the next sync, resulting in data loss. This will be solved in a future release, there is no workaround at the moment.

Files that change during a bisync run may result in data loss. This has been seen in a highly dynamic environment, where the filesystem is getting hammered by running processes during the sync. The currently recommended solution is to sync at quiet times or filter out unnecessary directories and files.

As an alternative approach, consider using --check-sync=false (and possibly --resilient) to make bisync more forgiving of filesystems that change during the sync. Be advised that this may cause bisync to miss events that occur during a bisync run, so it is a good idea to supplement this with a periodic independent integrity check, and corrective sync if diffs are found. For example, a possible sequence could look like this:

  1. Normally scheduled bisync run:
rclone bisync Path1 Path2 -MPc --check-access --max-delete 10 --filters-file /path/to/filters.txt -v --check-sync=false --no-cleanup --ignore-listing-checksum --disable ListR --checkers=16 --drive-pacer-min-sleep=10ms --create-empty-src-dirs --resilient
  1. Periodic independent integrity check (perhaps scheduled nightly or weekly):
rclone check -MvPc Path1 Path2 --filter-from /path/to/filters.txt
  1. If diffs are found, you have some choices to correct them. If one side is more up-to-date and you want to make the other side match it, you could run:
rclone sync Path1 Path2 --filter-from /path/to/filters.txt --create-empty-src-dirs -MPc -v  

(or switch Path1 and Path2 to make Path2 the source-of-truth)

Or, if neither side is totally up-to-date, you could run a --resync to bring them back into agreement (but remember that this could cause deleted files to re-appear.)

*Note also that rclone check does not currently include empty directories, so if you want to know if any empty directories are out of sync, consider alternatively running the above rclone sync command with --dry-run added.

Empty directories

By default, new/deleted empty directories on one path are not propagated to the other side. This is because bisync (and rclone) natively works on files, not directories. However, this can be changed with the --create-empty-src-dirs flag, which works in much the same way as in sync and copy. When used, empty directories created or deleted on one side will also be created or deleted on the other side. The following should be noted: * --create-empty-src-dirs is not compatible with --remove-empty-dirs. Use only one or the other (or neither). * It is not recommended to switch back and forth between --create-empty-src-dirs and the default (no --create-empty-src-dirs) without running --resync. This is because it may appear as though all directories (not just the empty ones) were created/deleted, when actually you've just toggled between making them visible/invisible to bisync. It looks scarier than it is, but it's still probably best to stick to one or the other, and use --resync when you need to switch.

Renamed directories

Renaming a folder on the Path1 side results in deleting all files on the Path2 side and then copying all files again from Path1 to Path2. Bisync sees this as all files in the old directory name as deleted and all files in the new directory name as new. Currently, the most effective and efficient method of renaming a directory is to rename it to the same name on both sides. (As of rclone v1.64, a --resync is no longer required after doing so, as bisync will automatically detect that Path1 and Path2 are in agreement.)

--fast-list used by default

Unlike most other rclone commands, bisync uses --fast-list by default, for backends that support it. In many cases this is desirable, however, there are some scenarios in which bisync could be faster without --fast-list, and there is also a known issue concerning Google Drive users with many empty directories. For now, the recommended way to avoid using --fast-list is to add --disable ListR to all bisync commands. The default behavior may change in a future version.

Overridden Configs

When rclone detects an overridden config, it adds a suffix like {ABCDE} on the fly to the internal name of the remote. Bisync follows suit by including this suffix in its listing filenames. However, this suffix does not necessarily persist from run to run, especially if different flags are provided. So if next time the suffix assigned is {FGHIJ}, bisync will get confused, because it's looking for a listing file with {FGHIJ}, when the file it wants has {ABCDE}. As a result, it throws Bisync critical error: cannot find prior Path1 or Path2 listings, likely due to critical error on prior run and refuses to run again until the user runs a --resync (unless using --resilient). The best workaround at the moment is to set any backend-specific flags in the config file instead of specifying them with command flags. (You can still override them as needed for other rclone commands.)

Case sensitivity

Synching with case-insensitive filesystems, such as Windows or Box, can result in file name conflicts. This will be fixed in a future release. The near-term workaround is to make sure that files on both sides don't have spelling case differences (Smile.jpg vs. smile.jpg).

Windows support

Bisync has been tested on Windows 8.1, Windows 10 Pro 64-bit and on Windows GitHub runners.

Drive letters are allowed, including drive letters mapped to network drives (rclone bisync J:\localsync GDrive:). If a drive letter is omitted, the shell current drive is the default. Drive letters are a single character follows by :, so cloud names must be more than one character long.

Absolute paths (with or without a drive letter), and relative paths (with or without a drive letter) are supported.

Working directory is created at C:\Users\MyLogin\AppData\Local\rclone\bisync.

Note that bisync output may show a mix of forward / and back \ slashes.

Be careful of case independent directory and file naming on Windows vs. case dependent Linux

Filtering

See filtering documentation for how filter rules are written and interpreted.

Bisync's --filters-file flag slightly extends the rclone's --filter-from filtering mechanism. For a given bisync run you may provide only one --filters-file. The --include*, --exclude*, and --filter flags are also supported.

How to filter directories

Filtering portions of the directory tree is a critical feature for synching.

Examples of directory trees (always beneath the Path1/Path2 root level) you may want to exclude from your sync: - Directory trees containing only software build intermediate files. - Directory trees containing application temporary files and data such as the Windows C:\Users\MyLogin\AppData\ tree. - Directory trees containing files that are large, less important, or are getting thrashed continuously by ongoing processes.

On the other hand, there may be only select directories that you actually want to sync, and exclude all others. See the Example include-style filters for Windows user directories below.

Filters file writing guidelines

  1. Begin with excluding directory trees:
  2. Decide if it's easier (or cleaner) to:
  3. Include select directories:
  4. Exclude select directories:

A few rules for the syntax of a filter file expanding on filtering documentation:

Example include-style filters for Windows user directories

This Windows include-style example is based on the sync root (Path1) set to C:\Users\MyLogin. The strategy is to select specific directories to be synched with a network drive (Path2).

- /AppData/
- NTUSER*
- ntuser*
+ /Documents/Family/**
+ /Documents/Sketchup/**
+ /Documents/Microcapture_Photo/**
+ /Documents/Microcapture_Video/**
+ /Desktop/**
+ /Pictures/**
+ /*
- **

Note also that Windows implements several "library" links such as C:\Users\MyLogin\My Documents\My Music pointing to C:\Users\MyLogin\Music. rclone sees these as links, so you must add --links to the bisync command line if you which to follow these links. I find that I get permission errors in trying to follow the links, so I don't include the rclone --links flag, but then you get lots of Can't follow symlink… noise from rclone about not following the links. This noise can be quashed by adding --quiet to the bisync command line.

How --check-access handles filters

At the start of a bisync run, listings are gathered for Path1 and Path2 while using the user's --filters-file. During the check access phase, bisync scans these listings for RCLONE_TEST files. Any RCLONE_TEST files hidden by the --filters-file are not in the listings and thus not checked during the check access phase.

Troubleshooting

Reading bisync logs

Here are two normal runs. The first one has a newer file on the remote. The second has no deltas between local and remote.

Dry run oddity

The --dry-run messages may indicate that it would try to delete some files. For example, if a file is new on Path2 and does not exist on Path1 then it would normally be copied to Path1, but with --dry-run enabled those copies don't happen, which leads to the attempted delete on Path2, blocked again by --dry-run: ... Not deleting as --dry-run.

This whole confusing situation is an artifact of the --dry-run flag. Scrutinize the proposed deletes carefully, and if the files would have been copied to Path1 then the threatened deletes on Path2 may be disregarded.

Rclone has built-in retries. If you run with --verbose you'll see error and retry messages such as shown below. This is usually not a bug. If at the end of the run, you see Bisync successful and not Bisync critical error or Bisync aborted then the run was successful, and you can ignore the error messages.

The following run shows an intermittent fail. Lines 5 and _6- are low-level messages. Line 6 is a bubbled-up warning message, conveying the error. Rclone normally retries failing commands, so there may be numerous such messages in the log.

Since there are no final error/warning messages on line 7, rclone has recovered from failure after a retry, and the overall sync was successful.

Denied downloads of "infected" or "abusive" files

Google Drive has a filter for certain file types (.exe, .apk, et cetera) that by default cannot be copied from Google Drive to the local filesystem. If you are having problems, run with --verbose to see specifically which files are generating complaints. If the error is This file has been identified as malware or spam and cannot be downloaded, consider using the flag --drive-acknowledge-abuse.

Google Doc files

Google docs exist as virtual files on Google Drive and cannot be transferred to other filesystems natively. While it is possible to export a Google doc to a normal file (with .xlsx extension, for example), it is not possible to import a normal file back into a Google document.

Bisync's handling of Google Doc files is to flag them in the run log output for user's attention and ignore them for any file transfers, deletes, or syncs. They will show up with a length of -1 in the listings. This bisync run is otherwise successful:

2021/05/11 08:23:15 INFO  : Synching Path1 "/path/to/local/tree/base/" with Path2 "GDrive:"

Usage examples

Cron

Rclone does not yet have a built-in capability to monitor the local file system for changes and must be blindly run periodically. On Windows this can be done using a Task Scheduler, on Linux you can use Cron which is described below.

The 1st example runs a sync every 5 minutes between a local directory and an OwnCloud server, with output logged to a runlog file:

# Minute (0-59)
#      Hour (0-23)
#           Day of Month (1-31)
#                Month (1-12 or Jan-Dec)
#                     Day of Week (0-6 or Sun-Sat)
#                         Command
  */5  *    *    *    *   /path/to/rclone bisync /local/files MyCloud: --check-access --filters-file /path/to/bysync-filters.txt --log-file /path/to//bisync.log

See crontab syntax for the details of crontab time interval expressions.

If you run rclone bisync as a cron job, redirect stdout/stderr to a file. The 2nd example runs a sync to Dropbox every hour and logs all stdout (via the >>) and stderr (via 2>&1) to a log file.

0 * * * * /path/to/rclone bisync /path/to/local/dropbox Dropbox: --check-access --filters-file /home/user/filters.txt >> /path/to/logs/dropbox-run.log 2>&1

Sharing an encrypted folder tree between hosts

bisync can keep a local folder in sync with a cloud service, but what if you have some highly sensitive files to be synched?

Usage of a cloud service is for exchanging both routine and sensitive personal files between one's home network, one's personal notebook when on the road, and with one's work computer. The routine data is not sensitive. For the sensitive data, configure an rclone crypt remote to point to a subdirectory within the local disk tree that is bisync'd to Dropbox, and then set up an bisync for this local crypt directory to a directory outside of the main sync tree.

Linux server setup

Windows notebook setup

rclone.conf snippet

[Dropbox]
type = dropbox
...

[Dropcrypt]
type = crypt
remote = /path/to/DBoxroot/crypt          # on the Linux server
remote = C:\Users\MyLogin\Dropbox\crypt   # on the Windows notebook
filename_encryption = standard
directory_name_encryption = true
password = ...
...

Testing

You should read this section only if you are developing for rclone. You need to have rclone source code locally to work with bisync tests.

Bisync has a dedicated test framework implemented in the bisync_test.go file located in the rclone source tree. The test suite is based on the go test command. Series of tests are stored in subdirectories below the cmd/bisync/testdata directory. Individual tests can be invoked by their directory name, e.g. go test . -case basic -remote local -remote2 gdrive: -v

Tests will make a temporary folder on remote and purge it afterwards. If during test run there are intermittent errors and rclone retries, these errors will be captured and flagged as invalid MISCOMPAREs. Rerunning the test will let it pass. Consider such failures as noise.

Test command syntax

usage: go test ./cmd/bisync [options...]

Options:
  -case NAME        Name(s) of the test case(s) to run. Multiple names should
                    be separated by commas. You can remove the `test_` prefix
                    and replace `_` by `-` in test name for convenience.
                    If not `all`, the name(s) should map to a directory under
                    `./cmd/bisync/testdata`.
                    Use `all` to run all tests (default: all)
  -remote PATH1     `local` or name of cloud service with `:` (default: local)
  -remote2 PATH2    `local` or name of cloud service with `:` (default: local)
  -no-compare       Disable comparing test results with the golden directory
                    (default: compare)
  -no-cleanup       Disable cleanup of Path1 and Path2 testdirs.
                    Useful for troubleshooting. (default: cleanup)
  -golden           Store results in the golden directory (default: false)
                    This flag can be used with multiple tests.
  -debug            Print debug messages
  -stop-at NUM      Stop test after given step number. (default: run to the end)
                    Implies `-no-compare` and `-no-cleanup`, if the test really
                    ends prematurely. Only meaningful for a single test case.
  -refresh-times    Force refreshing the target modtime, useful for Dropbox
                    (default: false)
  -verbose          Run tests verbosely

Note: unlike rclone flags which must be prefixed by double dash (--), the test command flags can be equally prefixed by a single - or double dash.

Running tests

Test execution flow

  1. The base setup in the initial directory of the testcase is applied on the Path1 and Path2 filesystems (via rclone copy the initial directory to Path1, then rclone sync Path1 to Path2).
  2. The commands in the scenario.txt file are applied, with output directed to the test.log file in the test working directory. Typically, the first actual command in the scenario.txt file is to do a --resync, which establishes the baseline {...}.path1.lst and {...}.path2.lst files in the test working directory (.../workdir/ relative to the temporary test directory). Various commands and listing snapshots are done within the test.
  3. Finally, the contents of the test working directory are compared to the contents of the testcase's golden directory.

Notes about testing

Updating golden results

Sometimes even a slight change in the bisync source can cause little changes spread around many log files. Updating them manually would be a nightmare.

The -golden flag will store the test.log and *.lst listings from each test case into respective golden directories. Golden results will automatically contain generic strings instead of local or cloud paths which means that they should match when run with a different cloud service.

Your normal workflow might be as follows: 1. Git-clone the rclone sources locally 2. Modify bisync source and check that it builds 3. Run the whole test suite go test ./cmd/bisync -remote local 4. If some tests show log difference, recheck them individually, e.g.: go test ./cmd/bisync -remote local -case basic 5. If you are convinced with the difference, goldenize all tests at once: go test ./cmd/bisync -remote local -golden 6. Use word diff: git diff --word-diff ./cmd/bisync/testdata/. Please note that normal line-level diff is generally useless here. 7. Check the difference carefully! 8. Commit the change (git commit) only if you are sure. If unsure, save your code changes then wipe the log diffs from git: git reset [--hard].

Structure of test scenarios

Supported test commands

Supported substitution terms

Substitution results of the terms named like {dir/} will end with / (or backslash on Windows), so it is not necessary to include slash in the usage, for example delete-file {path1/}file1.txt.

Benchmarks

This section is work in progress.

Here are a few data points for scale, execution times, and memory usage.

The first set of data was taken between a local disk to Dropbox. The speedtest.net download speed was ~170 Mbps, and upload speed was ~10 Mbps. 500 files (~9.5 MB each) had been already synched. 50 files were added in a new directory, each ~9.5 MB, ~475 MB total.

Change Operations and times Overall run time
500 files synched (nothing to move) 1x listings for Path1 & Path2 1.5 sec
500 files synched with --check-access 1x listings for Path1 & Path2 1.5 sec
50 new files on remote Queued 50 copies down: 27 sec 29 sec
Moved local dir Queued 50 copies up: 410 sec, 50 deletes up: 9 sec 421 sec
Moved remote dir Queued 50 copies down: 31 sec, 50 deletes down: <1 sec 33 sec
Delete local dir Queued 50 deletes up: 9 sec 13 sec

This next data is from a user's application. They had ~400GB of data over 1.96 million files being sync'ed between a Windows local disk and some remote cloud. The file full path length was on average 35 characters (which factors into load time and RAM required).

References

rclone's bisync implementation was derived from the rclonesync-V2 project, including documentation and test mechanisms, with [@cjnaz](https://github.com/cjnaz)'s full support and encouragement.

rclone bisync is similar in nature to a range of other projects:

Bisync adopts the differential synchronization technique, which is based on keeping history of changes performed by both synchronizing sides. See the Dual Shadow Method section in Neil Fraser's article.

Also note a number of academic publications by Benjamin Pierce about Unison and synchronization in general.

Changelog

v1.64

Release signing

The hashes of the binary artefacts of the rclone release are signed with a public PGP/GPG key. This can be verified manually as described below.

The same mechanism is also used by rclone selfupdate to verify that the release has not been tampered with before the new update is installed. This checks the SHA256 hash and the signature with a public key compiled into the rclone binary.

Release signing key

You may obtain the release signing key from:

After importing the key, verify that the fingerprint of one of the keys matches: FBF737ECE9F8AB18604BD2AC93935E02FF3B54FA as this key is used for signing.

We recommend that you cross-check the fingerprint shown above through the domains listed below. By cross-checking the integrity of the fingerprint across multiple domains you can be confident that you obtained the correct key.

If you find anything that doesn't not match, please contact the developers at once.

How to verify the release

In the release directory you will see the release files and some files called MD5SUMS, SHA1SUMS and SHA256SUMS.

$ rclone lsf --http-url https://downloads.rclone.org/v1.63.1 :http:
MD5SUMS
SHA1SUMS
SHA256SUMS
rclone-v1.63.1-freebsd-386.zip
rclone-v1.63.1-freebsd-amd64.zip
...
rclone-v1.63.1-windows-arm64.zip
rclone-v1.63.1.tar.gz
version.txt

The MD5SUMS, SHA1SUMS and SHA256SUMS contain hashes of the binary files in the release directory along with a signature.

For example:

$ rclone cat --http-url https://downloads.rclone.org/v1.63.1 :http:SHA256SUMS

Download the files

The first step is to download the binary and SUMs file and verify that the SUMs you have downloaded match. Here we download rclone-v1.63.1-windows-amd64.zip - choose the binary (or binaries) appropriate to your architecture. We've also chosen the SHA256SUMS as these are the most secure. You could verify the other types of hash also for extra security. rclone selfupdate verifies just the SHA256SUMS.

$ mkdir /tmp/check
$ cd /tmp/check
$ rclone copy --http-url https://downloads.rclone.org/v1.63.1 :http:SHA256SUMS .
$ rclone copy --http-url https://downloads.rclone.org/v1.63.1 :http:rclone-v1.63.1-windows-amd64.zip .

Verify the signatures

First verify the signatures on the SHA256 file.

Import the key. See above for ways to verify this key is correct.

$ gpg --keyserver keyserver.ubuntu.com --receive-keys FBF737ECE9F8AB18604BD2AC93935E02FF3B54FA
gpg: key 93935E02FF3B54FA: public key "Nick Craig-Wood <nick@craig-wood.com>" imported
gpg: Total number processed: 1
gpg:               imported: 1

Then check the signature:

$ gpg --verify SHA256SUMS 
gpg: Signature made Mon 17 Jul 2023 15:03:17 BST
gpg:                using DSA key FBF737ECE9F8AB18604BD2AC93935E02FF3B54FA
gpg: Good signature from "Nick Craig-Wood <nick@craig-wood.com>" [ultimate]

Verify the signature was good and is using the fingerprint shown above.

Repeat for MD5SUMS and SHA1SUMS if desired.

Verify the hashes

Now that we know the signatures on the hashes are OK we can verify the binaries match the hashes, completing the verification.

$ sha256sum -c SHA256SUMS 2>&1 | grep OK
rclone-v1.63.1-windows-amd64.zip: OK

Or do the check with rclone

$ rclone hashsum sha256 -C SHA256SUMS rclone-v1.63.1-windows-amd64.zip 
2023/09/11 10:53:58 NOTICE: SHA256SUMS: improperly formatted checksum line 0

Verify signatures and hashes together

You can verify the signatures and hashes in one command line like this:

$ gpg --decrypt SHA256SUMS | sha256sum -c --ignore-missing
gpg: Signature made Mon 17 Jul 2023 15:03:17 BST

1Fichier

This is a backend for the 1fichier cloud storage service. Note that a Premium subscription is required to use the API.

Paths are specified as remote:path

Paths may be as deep as required, e.g. remote:directory/subdirectory.

Configuration

The initial setup for 1Fichier involves getting the API key from the website which you need to do in your browser.

Here is an example of how to make a remote called remote. First run:

 rclone config

This will guide you through an interactive setup process:

No remotes found, make a new one?
n) New remote
s) Set configuration password
q) Quit config

Remote config
--------------------
[remote]
type = fichier
api_key = example_key
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y

Once configured you can then use rclone like this,

List directories in top level of your 1Fichier account

rclone lsd remote:

List all the files in your 1Fichier account

rclone ls remote:

To copy a local directory to a 1Fichier directory called backup

rclone copy /home/source remote:backup

Modified time and hashes

1Fichier does not support modification times. It supports the Whirlpool hash algorithm.

Duplicated files

1Fichier can have two files with exactly the same name and path (unlike a normal file system).

Duplicated files cause problems with the syncing and you will see messages in the log about duplicates.

Restricted filename characters

In addition to the default restricted characters set the following characters are also replaced:

Character Value Replacement
\ 0x5C
< 0x3C
> 0x3E
" 0x22
$ 0x24
` 0x60
' 0x27

File names can also not start or end with the following characters. These only get replaced if they are the first or last character in the name:

Character Value Replacement
SP 0x20

Invalid UTF-8 bytes will also be replaced, as they can't be used in JSON strings.

Limitations

rclone about is not supported by the 1Fichier backend. Backends without this capability cannot determine free space for an rclone mount or use policy mfs (most free space) as a member of an rclone union remote.

See List of backends that do not support rclone about and rclone about

Alias

The alias remote provides a new name for another remote.

Paths may be as deep as required or a local path, e.g. remote:directory/subdirectory or /directory/subdirectory.

During the initial setup with rclone config you will specify the target remote. The target remote can either be a local path or another remote.

Subfolders can be used in target remote. Assume an alias remote named backup with the target mydrive:private/backup. Invoking rclone mkdir backup:desktop is exactly the same as invoking rclone mkdir mydrive:private/backup/desktop.

There will be no special handling of paths containing .. segments. Invoking rclone mkdir backup:../desktop is exactly the same as invoking rclone mkdir mydrive:private/backup/../desktop. The empty path is not allowed as a remote. To alias the current directory use . instead.

The target remote can also be a connection string. This can be used to modify the config of a remote for different uses, e.g. the alias myDriveTrash with the target remote myDrive,trashed_only: can be used to only show the trashed files in myDrive.

Configuration

Here is an example of how to make an alias called remote for local folder. First run:

 rclone config

This will guide you through an interactive setup process:

No remotes found, make a new one?

rclone lsd remote:

List all the files in /mnt/storage/backup

rclone ls remote:

Copy another local directory to the alias directory called source

rclone copy /home/source remote:source

Standard options

Here are the Standard options specific to alias (Alias for an existing remote).

--alias-remote

Remote or path to alias.

Can be "myremote:path/to/dir", "myremote:bucket", "myremote:" or "/local/path".

Amazon Drive

Amazon Drive, formerly known as Amazon Cloud Drive, is a cloud storage service run by Amazon for consumers.

Status

Important: rclone supports Amazon Drive only if you have your own set of API keys. Unfortunately the Amazon Drive developer program is now closed to new entries so if you don't already have your own set of keys you will not be able to use rclone with Amazon Drive.

For the history on why rclone no longer has a set of Amazon Drive API keys see the forum.

If you happen to know anyone who works at Amazon then please ask them to re-instate rclone into the Amazon Drive developer program - thanks!

Configuration

The initial setup for Amazon Drive involves getting a token from Amazon which you need to do in your browser. rclone config walks you through it.

The configuration process for Amazon Drive may involve using an oauth proxy. This is used to keep the Amazon credentials out of the source code. The proxy runs in Google's very secure App Engine environment and doesn't store any credentials which pass through it.

Since rclone doesn't currently have its own Amazon Drive credentials so you will either need to have your own client_id and client_secret with Amazon Drive, or use a third-party oauth proxy in which case you will need to enter client_id, client_secret, auth_url and token_url.

Note also if you are not using Amazon's auth_url and token_url, (ie you filled in something for those) then if setting up on a remote machine you can only use the copying the config method of configuration - rclone authorize will not work.

Here is an example of how to make a remote called remote. First run:

Use web browser to automatically authenticate rclone with remote?
 * Say Y if the machine running rclone has a web browser you can use
 * Say N if running rclone on a (remote) machine without web browser access
If not sure try Y. If Y failed, try N.
y) Yes
n) No
y/n> y
If your browser doesn't open automatically go to the following link: http://127.0.0.1:53682/auth
Log in and authorize rclone for access

See the remote setup docs for how to set it up on a machine with no Internet browser available.

Note that rclone runs a webserver on your local machine to collect the token as returned from Amazon. This only runs from the moment it opens your browser to the moment you get back the verification code. This is on http://127.0.0.1:53682/ and this it may require you to unblock it temporarily if you are running a host firewall.

Once configured you can then use rclone like this,

List directories in top level of your Amazon Drive

rclone lsd remote:

List all the files in your Amazon Drive

rclone ls remote:

To copy a local directory to an Amazon Drive directory called backup

rclone copy /home/source remote:backup

Modified time and MD5SUMs

Amazon Drive doesn't allow modification times to be changed via the API so these won't be accurate or used for syncing.

It does store MD5SUMs so for a more accurate sync, you can use the --checksum flag.

Restricted filename characters

Character Value Replacement
NUL 0x00
/ 0x2F

Invalid UTF-8 bytes will also be replaced, as they can't be used in JSON strings.

Deleting files

Any files you delete with rclone will end up in the trash. Amazon don't provide an API to permanently delete files, nor to empty the trash, so you will have to do that with one of Amazon's apps or via the Amazon Drive website. As of November 17, 2016, files are automatically deleted by Amazon from the trash after 30 days.

Using with non .com Amazon accounts

Let's say you usually use amazon.co.uk. When you authenticate with rclone it will take you to an amazon.com page to log in. Your amazon.co.uk email and password should work here just fine.

Additional time per GiB to wait after a failed complete upload to see if it appears.

Sometimes Amazon Drive gives an error when a file has been fully uploaded but the file appears anyway after a little while. This happens sometimes for files over 1 GiB in size and nearly every time for files bigger than 10 GiB. This parameter controls the time rclone waits for the file to appear.

The default value for this parameter is 3 minutes per GiB, so by default it will wait 3 minutes for every GiB uploaded to see if the file appears.

You can disable this feature by setting it to 0. This may cause conflict errors as rclone re
