Reference: incremental backup
Purpose
An incremental backup includes new
CentreVu
CMS historical data
since the previous full or incremental backup. Incremental backups
may be a more efficient and less time-consuming way to back up your
CentreVu
CMS data when a full maintenance backup needs more than
one tape. But note that you must run a full backup before your first
incremental backup.
Allocate tapes
It is strongly recommended that you have an appropriate number of
extra tapes to rotate your tapes each week. In the following example,
you need two sets of four tapes so you can rotate the set of tapes
between the full backup and the incremental backups.
In this example, time constraints and personnel prevent the call center
from doing a full backup more than once a week, but the call center
wants to preserve the data in between full backups with incremental
backups during the week.
