How NetBackup determines which schedule to run next

When a policy contains one schedule, the schedule that is selected to run next is straightforward. But when a policy contains multiple schedules, choosing the schedule to run next can become more complicated.

Essentially, NetBackup performs two tasks to determine which schedule to run next.

First, NetBackup determines the due time for each schedule. The due time depends on the following:

The last backup data for each schedule based on comparable schedules.
The frequency that is added to each schedule to determine which schedule is due next.

Second, NetBackup checks the start time for each schedule. The schedule with the soonest start time runs next. That is, the schedule with the next open window.

The following topics describe how NetBackup determines which schedule to run next if a policy contains multiple schedules.
