Dear community 

i have a Hyper-V 2022 cluster with 3 nodes and unity dell for VMs location with fiber. I have configured the cluster correctly in Veeam, I can see the nodes and the VMs, but when I try to run a backup,

I get these errors: Processing VM Error: Value cannot be null. Parameter name: s or Unable to get target name for file: C:\ClusterStorage\Volume1\VM\Snapshots\6A204DB6-69D1-4634-A638-CACE086E003E.VMCX

What could be happening? Thanks!.
