incremental backup. For more information on how Data Protector selects media for

on page 108 depicts a scheduling policy based on a full backup plus simple
incremental backups.
Figure 28 Full backup with daily simple incremental backups
This policy reduces the media space and time needed for backing up, because you
only back up changes from the previous day. However, to restore files from a Thursday
backup, you need to provide the media for the full and each of the incremental
backups until Thursday, that is five media sets. This complicates and slows down the
restore.
