6.3.3 Restoring Backups

Click the Restore button in the

DESCRIPTION
Click Modify and then browse to the files and shares that you want to
back up.
A Normal backup is a complete copy of all files and folders selected.
Compression reduces the size of the file that you want to back up. Backup
is then faster, but restoring may be slower, so if backup space is not a
concern and recovery speed is, then turn off compression.
Use Purge to delete old backups. This purge policy applies to this specific
backup only, unlike snapshot purge policies which apply to all snapshots.
Purge runs first before a new backup is done. For example, if you have a
backup scheduled to begin at midnight, then at that time, the NSA checks
these settings and deletes files accordingly before backup takes place. If
space on the backup NSA or disk is a concern, then configure the NSA to
delete old backups.
• Keep All Old Backups: Purge is in effect disabled. Select this if
backup space is not a concern.
• Keep only last backup files: All backup files older than the last one
are deleted. You will not be able to recover files that existed (only) in
those previous backups. Select this if backup space is limited and
recovery of old files is not important.
• Keep backups for a period of day(s): Backups older than the
number of days you enter here are deleted. 0 days means that all old
backups are deleted when a new one is done.
