incremental backup. For more information on how Data Protector selects media for backups, see Selecting media for backups .

Example 1

Figure 28 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.

Example 2

Figure 29 on page 109 depicts a scheduling policy based on a full backup plus level one incremental backups.
