Verify synchronized files
The verify of synchronized data is triggered by the File -> Check synchronized menu or the ⌘K shortcut. The --archive parameter is the normal parameter to use in synchronize and snapshot tasks because it is fast. The --archive parameter to rsync preserves a lot of attributes of files when synchronizing. Files transferred in –archive mode ensures that symbolic links, devices, permissions, ownerships, modification times, ACLs, and extended attributes are preserved. When synchronizing files based upon the –archive parameter, rsync compares file size and last modification time to compute which files to be synchronized.
