Ignore specific tapes from autochanger

[David Masshardt]

I'm having some problems with Bareos and my tape autochanger. I'm using the same autochanger also for Proxmox backups. I've labeld the tapes for the Proxmox backup with a "P" prefix and those for bareos with a "B" prefix in the autochanger. The Proxmox backup tapes are not in the Bareos database, but for some reason Bareos sometimes wants to load those tapes for it's own backups. This results in an error message because the tapes are not empty and are labeled by the Proxmox Backup server.

Is there a way to tell Bareos to ignore tapes with an specific autochanger label prefix?

I also noticed that sometimes Bareos tries to append incremental backups to a tape that is in the differential pool and vice versa. Is there a way to fix this?
