I am having an issue with VDR. On several of my VM's, the backup fails with:

Failed to create snapshot for Saints DC, error -3941 ( create snapshot failed).

Points to note:

1. VDR has been rebooted several times
2. Disks have been formatted with 1MB blocks, but backups fail on VM/Disks with less than 256GB
3. Trying to snapshot a problem VM manually without memory but with quiesce ticked also fails
4. Backups work on "simple" VM's - standalone servers with no additional disks etc
5. I dont know if this is coincidence but all the VM's it is failing on have multiple disks. Even if I select only to backup the OS disk.
6. Backups fails on locally mounted disk or network share
