why this? "INFO: scsi0: dirty-bitmap status: disabled (VM not running)"

Backups are always incremental, why do you think they are not? You have to read the full disk but you save just the change to the backup.
As long as the VM is running, by using qemu dirty-bitmaps only the dirty-bitmap have to be in the backup.
Well if the VM is running, it finds and runs a dirty bitmap and only transfers the "delta".
What's happening with offline VMs. Is that it says because it's offline it's not using a bitmap and then transfering the full disk.
It appears of the server the backup is still incremental. But it's taking a LONG time to process/transfer offline VMs instead of less then 1-2 seconds for other VMS.

No, just analyse the backup log and the network traffic. Only changes are written to the backup store.
And yes, dirty-bitmap backups are ultrafast. In almost all server setups VM are running 24/7, so this is the normal use case for most.
is it possible to maybe have an option to help with backups related to offline VMs like...
Skip offline VMs if they have not been run since last backup?
Thanks for the info guys.
