You system performs a nightly backup of all the data in the /sales_data file system using ufsdump to an 8mm DAT tape. Recently, the backup stopped working because all the data no longer fits on a tape. The backup suspends while prompting for another tape volume.
Which strategy allows each nightly backup to fit on one tape?

A.
Taking a level one backup weekly and a level zero backup nightly.

B.
Talking a level zero backup each month, a level two backup each week, and a level 5 backup nightly.

C.
Taking a level 5 backup each month, a level six backup each week, and a level zero backup each night.

D.
Taking the full tape out in the morning, turning the tape over, replacing it in the drive, and allowing the backup to complete.

Explanation:

The nightly level 0 backup is using too much tape so decrease the amount of data being backed up nightly by using a nightly level 5 backup.
