Backup no power down with snapshots

[RailsGuy]

Hi all, I'm using ghettoVCB on ESXi 8 and have a question about power down and snapshots.

I'm was backing up a VM that has a user created snapshot with setting "POWER_VM_DOWN_BEFORE_BACKUP = 0". A dry run logged the following message, however, when I ran a backup it appears to have succeeded. I was expecting it to fail and was surprised the backup was taken. Should this have failed and is the resulting backup valid or corrupt?

Dry run

dryrun: VMDK(s): 
dryrun: 	Basic TEST VM-000001.vmdk	0 GB
dryrun: INDEPENDENT VMDK(s): 
dryrun: TOTAL_VM_SIZE_TO_BACKUP: 0 GB
dryrun: THIS VIRTUAL MACHINE WILL NOT BE BACKED UP DUE TO EMPTY VMDK LIST!

Backup
