6.3.3  Restoring Backups
Click the Restore button in the 
Protect > Backup
 screen to replace existing files with files 
saved previously.
Modify
Click Modify and then browse to the files and shares that you want to 
back up.
Advanced Settings
Backup Method:
Normal backup is a complete copy of all files and folders selected.
Use Compression
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.
Purge Settings:
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.
