Defining a new start window when automatic backup is not running

If you define a planned start time that is later than the time that automatic backup last ended, automatic backup starts at the new planned start time if it has not already processed all the requested volumes on this day. Otherwise, automatic backup starts at the new planned start time on the next day.

If you define a planned start time that is earlier than the time that automatic backup last ended, automatic backup starts only if it has not run to completion on this day.
