This question may be a bit naive, but I'm looking to do offsite tape vaulting, and I'm looking for some more info. The environment was setup before I was hired, but offsite tape vaulting has never been done.

Our environment:
RHEL 7.3
SP version 8.1.4
primary backup - directory-container stgpool on raid disks
TS4300 tape library - we have a script run daily that uses the protect command to copy to tape.
All of these are in the same server room.

The SP knowledge centre has the necessary info on the command to remove/replace tapes. My question is more about how it works. I'm guessing, I just remove all tapes that have data on them (ie, not scratch) and move them to a separate building. Is this correct?

And, after that, wouldn't the server need to copy the entire storage pool over to tape again? Which, would take a long time I imagine.

Supposing I want to do this every 2 weeks, or every month. Would I remove data tapes, and then put the old ones back, and set them as scratch?

Everytime you run protect stgpool type-local, it copies to tape extents not previously sent to tape. The location of the tape is not relevant to that process.

So you can do this daily, move the new copy tapes out to the vault daily. The protect also does the reclamation by default of the copy tapes, you would not notice this because the tapes were in the library. Once the copy tapes are offsite, you'll want to bring them back onsite once returned to scratch.
