My goal is to always keep 2-3 weeks of media at the tape at one time and overwrite older weeks automatically without overwriting the entire tape once it gets full.
If you are saying what I think you are saying, you can't do it. Once a tape fills up, all you can do is Overwrite, which effecivly does a quick erase, and any data on the tape is no longer retrievable (remember that tape is sequential access not random access)
If you want three weeks of data, if the complete week will fit in on one tape, you'll need three tapes, one for each week, and two jobs, An Overwrite on Monday, and an Append the rest of the week
I take that back
You could have one job, defined as "Append, else Overwrite", and the media set APP set to 5 days, OPP to 13 days. You'll still need three tapes though
