File baCkup/restore
The File Backup and Recovery function is similar to the Share Disk Replication Backup and Recovery, except
instead of backing up the entire contents of a Share Disk, you choose individual les to backup. Also there is
an additional policy mode
Version which syncs all le changes in a new folder, effectively saving a new time-
stamped version of the le. The Version policy allows restoration of backed up versions of les, selected according
to the time created.
