I'm seeing this error for every configured VM on this particular volume when I run a test:
Error - Virtual machines "MBRDBPRDRestore1120" that are not protected by this protection group use datastores "VM_1ALB_T1_VOL1" that are in this protection group.
This vm is a copy of a vm that is in the protection group but it was restored to a different volume with a different name.
When I browse the datastore I'm not finding any files that look like they are related to the restored vm.
Any ideas?
