I'm failing miserably here, I've tried as suggested, just to be clear my backup is of the parent VM, it's not a backup of the replica at the primary site. When I follow the steps outlined in your link I get "VM not found in backup for initial seed" even though I've scanned the repository, it finds the backup file, i can see the backup file in Veeam. Then I tried restoring the VM files to the datastore and mapped the replication to the VM, this fails with "A snapshot operation cannot be performed.
Error: A snapshot operation cannot be performed."
I'm struggling here, any idea?
