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. **Note**: Use the `-P`/`--progress` flag to view real-time transfer statistics ``` rclone sync source:path dest:path [flags] ``` ## Options ``` --create-empty-src-dirs Create empty source dirs on destination after sync -h, --help help for sync ``` See the [global flags page](/flags/) for global options not listed here. ## SEE ALSO * [rclone](/commands/rclone/) - Show help for rclone commands, flags and backends.
