Just looking to confirm some logic here...

If some (not all) savesets and dependencies have expired on a tape that doesn't mean that space can be reused for some backup job looking for media? Correct?

I assume all savesets and dependencies need to expire before the tape can be recycled and reused? Correct?

I have ran out of usable tapes and it seems the savesets are oddly spread across multiple tapes so nothing can be reused. I'm trying to understand whats going on here so I can move forward with troubleshooting.

Thanks
