Configure
First you'll need to configure rclone. As the object storage systems
have quite complicated authentication these are kept in a config file
.rclone.conf in your home directory by default. (You can use the
--config option to choose a different config file.)
The easiest way to make the config is to run rclone with the config
option:
rclone config
See the following for detailed instructions for
- Google drive
- Amazon S3
- Swift / Rackspace Cloudfiles / Memset Memstore
- Dropbox
- Google Cloud Storage
- Local filesystem
- Amazon Cloud Drive
- Backblaze B2
- Hubic
- Microsoft One Drive
- Yandex Disk
Usage
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, eg
"drive:myfolder" to look at "myfolder" in Google drive.
You can define as many storage paths as you like in the config file.
Subcommands
rclone copy source:path dest:path
Copy the source to the destination. Doesn't transfer
unchanged files, testing by size and modification time or
MD5SUM. Doesn't delete files from the destination.
rclone sync source:path dest:path
Sync the source to the destination, changing the destination
only. Doesn't transfer unchanged files, testing by size and
modification time or MD5SUM. Destination is updated to match
source, including deleting files if necessary.
Important: Since this can cause data loss, test first with the
--dry-run flag to see exactly what would be copied and deleted.
Note that files in the destination won't be deleted if there were any
errors at any point.
rclone ls remote:path
List all the objects in the the path with size and path.
rclone lsd remote:path
List all directories/containers/buckets in the the path.
rclone lsl remote:path
List all the objects in the the path with modification time,
size and path.
rclone md5sum remote:path
Produces an md5sum file for all the objects in the path. This
is in the same format as the standard md5sum tool produces.
rclone sha1sum remote:path
Produces an sha1sum file for all the objects in the path. This
is in the same format as the standard sha1sum tool produces.
rclone size remote:path
Prints the total size of objects in remote:path and the number of
objects.
rclone mkdir remote:path
Make the path if it doesn't already exist
rclone rmdir remote:path
Remove the path. Note that you can't remove a path with
objects in it, use purge for that.
rclone purge remote:path
Remove the path and all of its contents. Note that this does not obey
include/exclude filters - everything will be removed. Use delete if
you want to selectively delete files.
rclone delete remote:path
Remove the contents of path. Unlike purge it obeys include/exclude
filters so can be used to selectively delete files.
Eg delete all files bigger than 100MBytes
Check what would be deleted first (use either)
rclone --min-size 100M lsl remote:path
rclone --dry-run --min-size 100M delete remote:path
Then delete
rclone --min-size 100M delete remote:path
That reads "delete everything with a minimum size of 100 MB", hence
delete all files bigger than 100MBytes.
rclone check source:path dest:path
Checks the files in the source and destination match. It
compares sizes and MD5SUMs and prints a report of files which
don't match. It doesn't alter the source or destination.
rclone dedupe remote:path
Interactively find duplicate files and offer to delete all but one or
rename them to be different. Only useful with Google Drive which can
have duplicate file names.
$ rclone dedupe drive:dupes

rclone config
Enter an interactive configuration session.
rclone help
Prints help on rclone commands and options.
Server Side Copy
Drive, S3, Dropbox, Swift and Google Cloud Storage 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 (eg local) 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.
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, eg
rclone sync remote:current-backup remote:previous-backup
rclone sync /path/to/files remote:current-backup
Options
Rclone has a number of options to control its behaviour.
Options which use TIME use the go time parser. 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". Valid
time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
Options which use SIZE use kByte by default. However a suffix of k
for kBytes, M for MBytes and G for GBytes may be used. These are
the binary units, eg 2**10, 2**20, 2**30 respectively.
--bwlimit=SIZE
Bandwidth limit in kBytes/s, or use suffix k|M|G. The default is 0
which means to not limit bandwidth.
For example to limit bandwidth usage to 10 MBytes/s use --bwlimit 10M
This only limits the bandwidth of the data transfer, it doesn't limit
the bandwith of the directory listings etc.
--checkers=N
The number of checkers to run in parallel. Checkers do the equality
checking of files during a sync. For some storage systems (eg 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.
-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, eg 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.
--config=CONFIG_FILE
Specify the location of the rclone config file. Normally this is in
your home directory as a file called .rclone.conf. If you run
rclone -h and look at the help for the --config option you will
see where the default location is for you. Use this flag to override
the config location, eg rclone --config=".myconfig" .config.
--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.
-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.
--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.
--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.
--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.
-q, --quiet
Normally rclone outputs stats and a completion message. If you set
this flag it will make as little output as possible.
--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 helps pick up the
files which didn't get transferred because of errors.
Disable retries with --retries 1.
--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.
When using this flag, rclone won't update mtimes of remote files if
they are incorrect as it would normally.
--stats=TIME
Rclone will print stats at regular intervals to show its progress.
This sets the interval.
The default is 1m. Use 0 to disable.
--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.
Specifying --delete-during (default value) will delete files while checking
and uploading files. This is usually the fastest option.
Specifying --delete-after will delay deletion of files until all new/updated
files have been successfully transfered.
--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.
-v, --verbose
If you set this flag, rclone will become very verbose telling you
about every file it considers and transfers.
Very useful for debugging.
-V, --version
Prints the version number
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 eg
--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-bodies
Dump HTTP headers and bodies - may contain sensitive info. 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-headers
Dump HTTP headers - may contain sensitive info. Can be very verbose.
Useful for debugging only.
--memprofile=FILE
Write memory profile to file. This can be analysed with go tool pprof.
--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.
Filtering
For the filtering options
--delete-excluded--filter--filter-from--exclude--exclude-from--include--include-from--files-from--min-size--max-size--min-age--max-age--dump-filters
