There is definitely a bug in the license validation / lifecycle management. (files presumably are leftovers from years of license upgrades, however this only became a issue now, presumably due to either a keyfile counter > 3 , last replacement during Plus had no issues) Ticket opened with support.

So if you don't backup "All" VMs and rename a VM it will not be backed up anymore due to referencing to VMs by names instead of instead of uuID's... virsh list --all --uuid --name
