Cataloging Tapes - BE2010
I am cataloging a set of tapes from our archives. The tape set was all removed at the same time, so I am wondering why the catalog process is asking for multiple tapes from a prior backup set (one at a time, I might add). The catalog job is currently running and I can see so far that the job has only processed the first tape in the set, but has asked for 3 other tapes not in the set. I am worried that when the job finally gets to the next tape in the set, it is going to ask me for additional tapes not in the set and this is going to be a very lengthy process to catalog 6 tapes. Also, since we recycle tapes on a bi-monthly basis, what happens if the catalog job asks for a tape that has already been erased/reused? Is this the correct way to catalog tapes? I'd appreciate any comments. I am going through this process because we lost our catalog file and didn't have a backup.
Background Info on our process: We remove all tapes that are full on a weekly basis and label them with date and slot position. Any empty tapes are left in the drive. We are using an Exabyte LTO 1x7 2U unit.
