Hi @DustinB
The VM could be backed up successfully with the same warning about the "disk parent":

I am using "smart mode" for backup jobs. The standalone job went through with and without "smart mode".
Removing the tag from the VM in question and adding it again did not help. I have also deleted the snapshot linked to the backup job and retried, with no change in behavior.
The VM is shutdown and I only turn it on when I need to. During backup it is usually not running.
Thanks again.

Marc
