I was wondering if anyone could help out a bit configuring an tape autoloader in the way i would like it to run. Have to admit its been a while since i last used a tape libary but in these crypo-times tape is suddently back in fashon again

Short about our setup
We are running Veeam B&R 12.1.1.56 with a few disk repos and we have now added a DELL TL4000 with LTO-7 drive to this infrastructure. We would like to run a copy job of all repo's to the autoloader for a extra copy.
This autoloader has 4 magazines giving me 48 slots with tapes with IO stations disabled. Our data amount is too large to fit to one tape, so a complete backup will be spanned over several tapes. The idea is to get weekly and monthly full backups to tape and remove from the autoloader so its untouchable. I also have 2 spare mag's for the autoloader and will buy more when needed.
How do i go about in the world of media pools and vaults to have the autoloader put the rights tape into the correct magazine after the job is finished? this would save us from ejecting single tapes and just swapping a magazine when its full. We would then insert a new mag with either blank tapes or old ones ready for overwrite.
Should i setup one vault per mag? How should the media pools be setup in this case? Should i use a standard pool or the GFS option?
Should it take tapes from where ever, then put them in a specified magazine when done?
Any pointers in the right direction is highly appriciated

Cheers
Ray
