If you mean DLT IV, the capacity is 35/70GB. You only get 70GB at 2:1
compression. Some sites get that and some don't, depending on your data
(I've seen more like 1.3-1.6 in real world). Are the tapes marked full?
The available_media report will tell you.
A couple pieces of data are missing: your number of drives and MPX per
drive. If you have MPX set low (e.g., 1) and have 6 drives, then NetBackup
may try to use all drives at once to speed your restore.
