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]
Options
--create-empty-src-dirs Create empty source dirs on destination after copy
-h, --help help for copy
Copy Options
Flags for anything which can Copy a file.
--check-first Do all the checks before starting transfers
-c, --checksum Check for changes with size & checksum (if available, or fallback to size only).
--compare-dest stringArray Include additional comma separated server-side paths during comparison
--copy-dest stringArray Implies --compare-dest but also copies files from paths into destination
--cutoff-mode HARD|SOFT|CAUTIOUS Mode to stop transfers when reaching the max transfer limit HARD|SOFT|CAUTIOUS (default HARD)
--ignore-case-sync Ignore case when synchronizing
--ignore-checksum Skip post copy check of checksums
--ignore-existing Skip all files that exist on destination
--ignore-size Ignore size when skipping use modtime or checksum
-I, --ignore-times Don't skip files that match size and time - transfer all files
--immutable Do not modify files, fail if existing files have been modified
--inplace Download directly to destination file instead of atomic download to temp/rename
--max-backlog int Maximum number of objects in sync or check backlog (default 10000)
--max-duration Duration Maximum duration rclone will transfer data for (default 0s)
--max-transfer SizeSuffix Maximum size of data to transfer (default off)
-M, --metadata If set, preserve metadata when copying objects
--modify-window Duration Max time diff to be considered the same (default 1ns)
--multi-thread-chunk-size SizeSuffix Chunk size for multi-thread downloads / uploads, if not set by filesystem (default 64Mi)
--multi-thread-cutoff SizeSuffix Use multi-thread downloads for files above this size (default 256Mi)
--multi-thread-streams int Number of streams to use for multi-thread downloads (default 4)
--multi-thread-write-buffer-size SizeSuffix In memory buffer size for writing when in multi-thread mode (default 128Ki)
--no-check-dest Don't check the destination, copy regardless
--no-traverse Don't traverse destination file system on copy
--no-update-modtime Don't update destination modtime if files identical
--order-by string Instructions on how to order the transfers, e.g. 'size,descending'
--partial-suffix string Add partial-suffix to temporary file name when --inplace is not used (default ".partial")
--refresh-times Refresh the modtime of remote files
--server-side-across-configs Allow server-side operations (e.g. copy) to work across different configs
--size-only Skip based on size only, not modtime or checksum
--streaming-upload-cutoff SizeSuffix Cutoff for switching to chunked upload if file size is unknown, upload starts after reaching cutoff or when file ends (default 100Ki)
-u, --update Skip files that are newer on the destination
Important Options
Important flags useful for most commands.
-n, --dry-run Do a trial run with no permanent changes
-i, --interactive Enable interactive mode
-v, --verbose count Print lots more stuff (repeat for more)

Listing Options
Flags for listing directories.
--default-time Time Time to show if modtime is unknown for files and directories (default 2000-01-01T00:00:00Z)
