So there is exactly one dirty-bitmap that get's nulled after a backup? I'm asking because I have Backup setups with 2 Backup Servers at different Locations, backing up (file-level, incremental) on odd days to server1 on even days to server2. Such a setup wouldn't work with the block level incremental backup and the dirty-bitmap for pve vms + pbs, right? Regards, Tom
