Reference: complex backup
Purpose
You may need a different combination of incremental and full backups
to meet the needs of your call center. This is called a complex backup.
Use at least two sets of backup tapes when running a complex backup.
Important! If at any time an incremental tape is damaged, run a full
backup immediately. If an incremental backup fails, fix the failure and
run another incremental backup.
Allocate tapes
In the next example, the call center does a full backup only every two
weeks on a Saturday, with incremental backups done Monday through
Friday. A full backup could need more than three tapes.
