I am trying to develop a backup strategy for DU 4.0E but
dont quite understand the incremental levels. Would
someone be so kind as to explain the following strategies.

Case 1: backup levels are for Mon-Fri
         0 9 9 9 9

         if i lose the disk on Sat I assume I would have to
         use the level 0 disk and the last level 9 disk.
         Correct?

Case 2: 0 4 1 3 1

         if i lose the disk after the wed backup(first
         level 1) i would have to use the level 0 and the
         first level 1 backup?

         if i lose the data after the thurs backup(level
         3) i would need the level 0, 1 and 3 tapes.

         if i lose the data after the last level 1 backup
         (friday) i would need only the level 0 and the
          last level 1.

         are these assumptions correct?

thanks,
