I have robotic library with two drives. There's a day in week when only full and duplicate-to-tape jobs are scheduled for my servers. No other jobs are scheduled. Sometimes a job can take little longer than expected and then another job in a row picks up another tape and starts to using it. And I do not want that. All of my backed up data fits into single tape easily. The job schedule is pretty tight, rescheduling is not a way to solve my problem.
