Figure 8: Differential backup (single mode)
DP snapshot1 remains on the snapshot tree to track changes made since the last full backup.
A backup chain consisting of a full backup that is followed by incremental sessions progresses in
the same way, with the exception that, at the end of an incremental session, DP snapshot1 is
removed instead of DP Snapshot2 (see Figure 9 Incremental backup (single mode)).
