It should be possible to maintain exclusions in the monitoring checks for VMs that should not be backed up or cannot be backed up (due to compatibility issues).
Excluding individual VMs makes more sense than creating a whitelist for all VMs to be checked, as the latter approach is prone to errors when new servers are added.
Additionally, for Hyper-V backups, the VM name should be displayed (if available in the log) rather than just the generic string assigned by the backup job itself.
