Managing Portal Snapshots (Backups)
          The CTERA Portal retains previous file versions for each user, by using snapshots. Snapshots are read-only copies of files as they were at a particular point-in-time.
          The CTERA Portal creates snapshots automatically and retains them according to a configurable snapshot retention policy. So long as a snapshot is retained by CTERA Portal, the relevant version of the user data can be retrieved.
