Yikes, thought it was. I have it enabled. Somewhere in the PBS info for 1.0-9 there was information about "touch tape.cfg"
I was not expecting much, was able to add drive and library, and thats about its, stuck on inventory.
unable to read json "/var/lib/proxmox-backup/tape/inventory.json" - Permission denied (os error 13
Wll look forward to progress, that for the feedback
