Tape not overwritable when loads of space
This is probably a basic issue but I am having trouble running a system of backups to tape. I use 9.1 rev 4691 on Windows Server 2003 SP2. Each week I run a FULL backup which then duplicates to ta...

Ah! The Full goes to a Media Set that is a NAS folder, and so does the Incremental. But these are different media sets as they are in different folders on the NAS. This seems to work fine. The tape media sets are also different because I needed to distinguish between the cycles of OPP and APP. So 4 media sets in all with 3 tapes.
Looking at this now, if in the 2nd week I had a restore to do on an Incremental and the NAS had blown a fuse - I would blow a fuse too! As it would have been overridden.
Basically I am storing about 2 months of backups on NAS with weekly FULL and 4 Incrementals and then this is also sent to tape using the Duplicate job. The tapes though only would take me back 2 weeks as I have just 2 Full tapes I interchange. The incremental will only take me back 1 week.
So if I have to have the tape media on one set for both Full and Incremental how do I set this up so as to keep the status quo or should I have a different routine completely?! Maybe: 4 tapes (2 Full and 2 Incr) OPP is 13/14 days (I tend to take one day off in case I have an o'night error and have to run the job again the next day - as this can really mess things up) and the APP is Infinate. Would that work? Oh, my head hurts...!
