How open schedules affect calendar-based and frequency-based schedules

A single backup window can span the entire week. This kind of schedule is called an open schedule because a job may run at any time of day or night during the week. Open schedules affect calendar-based and frequency-based schedules differently.

Figure: An open schedule shows an open schedule.

Open schedules affect calendar-based and frequency-based schedules differently:

Calendar-based schedules

Calendar-based schedules run whenever the calendar schedule indicates. NetBackup assumes that an environment requires one backup on each day that is selected on the calendar schedule. Given an open schedule, backups run as soon after midnight as possible to satisfy the daily backup requirement.

Frequency-based schedules

Frequency-based schedules run when the frequency setting indicates. For example, with a frequency of one day, NetBackup runs backups at 24-hour intervals based on the start time.

Figure: An open schedule that is calendar-based shows that the backups on a calendar-based schedule would run Monday through Friday.

Figure: An open schedule that is frequency-based and Figure: Example of a frequency-based schedule with an open schedule show that the backups based on a frequency-based schedule should run every day of the week, including Saturday and Sunday.
