~ Need assistance in creating a backup solution ~

BinaryPirate: Yes.

If you want a Daily/Weekly/Monthly backup routine, then you need to consider a GFS policy...Grandfather/Father/Son.

It's simple and easy to setup. You'd create the GFS policy, which starts with the Monthly job being created. This includes your Append/OPP settings, naming your media set (or selecting a pre-existing media set), selecting partitions (if you use them in a tape autoloader/library) etc. along with naming this. You'd move on to the Weekly configuration, and then the Daily configuration.

Each is going to have its own media set. Different retention times mean this is required. No sense in having 1 media set for everything where tapes can be overwritten, and you end up losing a Monthly for instance.

Once done, select a selection list and you're ready to go.

I suspect what's happening is that you have 1 media set and are trying to retrofit a GFS backup strategy into this which won't work. A policy is easily managed & I'd recommend it. Tapes belong to media sets and are not used by others. If you have an autoloader/library, you can further segment the tapes physically by creating partitions.
