Full Backup Vs Incremental
full backup is never included in an incremental strategy. Thus, an incremental level 0 is
a full backup that happens to be the parent of incremental backups whose level is
greater than 0.
A level 1 incremental backup can be either of the following types:
■ A differential incremental backup, which backs up all blocks changed after the
most recent incremental backup at level 1 or 0
■ A cumulative incremental backup, which backs up all blocks changed after the
most recent incremental backup at level 0
Incremental backups are differential by default.
Note: Cumulative backups are preferable to differential backups
when recovery time is more important than disk space, because
fewer incremental backups need to be applied during recovery.
