## rclone sync
|
|
|
|
Make source and dest identical, modifying destination only.
|
|
|
|
### Synopsis
|
|
|
|
|
|
|
|
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.
|
|
|
|
It is always the contents of the directory that is synced, not the
|
|
directory 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 above if unsure.
|
|
|
|
If dest:path doesn't exist, it is created and the source:path contents
|
|
go there.
|
|
|
|
|
|
```
|
|
rclone sync source:path dest:path [flags]
|
|
```
|
|
|
|
