untill 2 years ago we had a bed practis of using multipel tape for one backup job, we have a tape library and we have a full backup job, when we ran this job once a month the data wouldn't fit on one tape so the rest of the data writen to tape 2 and next month full backup the same data wouldn't fit to the current tape 2 and the rest of data goes to tape 3 and next month to tape 4. we stop this practics. and now each full backup has its own tape.
now I have 4 tapes with above story, and I want to reuse the first 2 tapes. I want to be sure if I need to restore data from the tape 3 and tape 4, still I can do so. I heard this is possible but then I have to catalog each of the last 2 tapes again with the option Use storage media-based catalogs is not selected.
is this correct?
