Backup Method:
A 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

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.
