Use: "copy source:path dest:path",
|
|
Short: `Copy files from source to dest, skipping identical files.`,
|
|
// Note: "|" will be replaced by backticks below
|
|
Long: strings.ReplaceAll(`
|
|
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](/commands/rclone_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](/commands/rclone_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](/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
|
|
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.
