How does the permissions backup and restore function work?
• Backups can be scheduled using the user interface or command line, and copy all permissions relating to files and folders into a flat file anywhere you choose. This is a fast operation since it does not backup the data, but only the permissions information. Restoring permissions is as simple as selecting a backup file, navigating down to where you want to repair permissions and restoring them to how they were at the time of the backup.
