# rclone copy
2016-08-04 04:36:28 +08:00
2021-11-01 23:42:05 +08:00
Copy files from source to dest, skipping identical files.
2016-08-04 04:36:28 +08:00
2020-05-22 18:17:37 +08:00
## Synopsis
2016-08-04 04:36:28 +08:00
2021-11-01 23:42:05 +08:00
Copy the source to the destination. Does not transfer files that are
identical on source and destination, testing by size and modification
2022-07-10 01:08:20 +08:00
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 ](/commands/rclone_sync/ ) command instead.
2016-08-04 04:36:28 +08:00
2021-11-01 23:42:05 +08:00
Note that it is always the contents of the directory that is synced,
2022-07-10 01:08:20 +08:00
not the directory itself. So when source:path is a directory, it's the
2021-11-01 23:42:05 +08:00
contents of source:path that are copied, not the directory name and
contents.
2016-08-04 04:36:28 +08:00
2022-07-10 01:08:20 +08:00
To copy single files, use the [copyto ](/commands/rclone_copyto/ )
command instead.
2021-11-01 23:42:05 +08:00
If dest:path doesn't exist, it is created and the source:path contents
go there.
For example
2016-08-04 04:36:28 +08:00
rclone copy source:sourcepath dest:destpath
2021-11-01 23:42:05 +08:00
Let's say there are two files in sourcepath
2016-08-04 04:36:28 +08:00
sourcepath/one.txt
sourcepath/two.txt
2021-11-01 23:42:05 +08:00
This copies them to
2016-08-04 04:36:28 +08:00
destpath/one.txt
destpath/two.txt
2021-11-01 23:42:05 +08:00
Not to
2016-08-04 04:36:28 +08:00
destpath/sourcepath/one.txt
destpath/sourcepath/two.txt
If you are familiar with `rsync` , rclone always works as if you had
2021-02-02 21:42:35 +08:00
written a trailing `/` - meaning "copy the contents of this directory".
2016-08-04 04:36:28 +08:00
This applies to all commands and whether you are talking about the
source or destination.
2019-02-09 18:42:57 +08:00
See the [--no-traverse ](/docs/#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
2020-05-16 22:11:55 +08:00
them change every day, you can copy all the files which have changed
recently very efficiently like this:
2019-02-09 18:42:57 +08:00
rclone copy --max-age 24h --no-traverse /path/to/src remote:
2024-03-10 19:22:43 +08:00
Rclone will sync the modification times of files and directories if
the backend supports it. If metadata syncing is required then use the
`--metadata` flag.
Note that the modification time and metadata for the root directory
will **not** be synced. See https://github.com/rclone/rclone/issues/7652
for more info.
2020-09-02 23:59:04 +08:00
**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.
