Off-topic, I used to have to manage backups on LTO tapes back in the
mid-2000's. It was a constant source of problems, like the ones you

We moved away from LTO and switched to a SAN connected to the backup
server with an iSCSI interface. Most of the problems went away after
switching to disks. Disks were faster than LTO, and iSCSI was more
than enough to handle the backup traffic. There were also fewer disks
than tapes so the offsite backup package got smaller.

You might consider doing the same since disks are so inexpensive. Sell
the used tape deck, libraries and tapes on eBay. It will pay for the
SAN. Buy a LTO degausser for the bulk erase
