Dump Levels for Daily, Discrete Backups

The following example shows a schedule where you capture only a day's work on different tapes. In this case, sequential dump level numbers are used during the week (3,4,5,6) with a lower number (2) on Friday.

Figure 45–2 Incremental Backup: Daily Discrete

Illustration shows approximately equal amount of tape needed for a daily discrete backup that starts on Monday and finishes on Friday.

In the preceding example, you could have used the sequence 6, 7, 8, 9 followed by 2, or 5, 6, 7, 8 followed by 3. Remember, the numbers themselves have no defined meaning. You attribute meaning by ordering them in a high/low sequence.
