Doesn't transfer files that are identical on source and destination, testing by size and modification time or MD5SUM. Destination is updated to match source, including deleting files if necessary (except duplicate objects, see below). If you don't want to delete files from destination, use the [copy](/commands/rclone_copy/) command instead. **Important**: Since this can cause data loss, test first with the ` + "`--dry-run` or the `--interactive`/`-i`" + ` flag. rclone sync -i SOURCE remote:DESTINATION Note that files in the destination won't be deleted if there were any errors at any point. Duplicate objects (files with the same name, on those providers that support it) are also not yet handled. 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. See extended explanation in the [copy](/commands/rclone_copy/) command 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 **Note**: Use the ` + "`rclone dedupe`" + ` command to deal with "Duplicate object/directory found in source/destination - ignoring" errors.
