About snapshot-assisted backups
Since a snapshot set created using SFW is an exact copy of the production data, it can be used with a backup application in place of the production volumes to produce regular backups to tape or other media. A snapshot set can be used for backup either on-host or moved to a secondary server.
A snapshot-assisted backup provides the following advantages:
Reduces backup I/O load on the production volumes in an on-host environment, allowing backup to be completed with less impact to the users
Eliminates backup I/O load on the production server in an off-host environment
