Scheduling is based off of classes.
To have a common schedule throughout your classes, utilize the copy option
when creating new schedules. With schedules, you may override the default
storage unit and volume pool for the class in question. You specify within
the schedule what type of backup (full, cumulative, differential, user
backup, or user archive) as well as the retention period, frequency, and
whether or not to multiplex. You also specify the start time and window
for the backup schedule.
