Join Veeam Appliance 13 to domain or Not to backup Hyper-v 2025 Cluster

[fbroussey]

Hi, I just want to know if it is mandatory to join the veeam Appliance 13 to the active directory domain which hyper-vhosts belong in order to backup Vms from this Hyper-v cluster.
We don’t usually do that for security reasons but i'm facing a pb with the add of a 2025 Hyper-v Cluster to Veeam 13 giving me an error :
Failed to connect to cluster cluster.clusterhv.local
Failed to create Hyper-V Cluster Wmi utils: Failed to test connection to the host cluster.clusterhv.local with OMICLI.
Possible reason:
Specified host is not a cluster node.
I open a case Veeam Software Appliance #07899013 but i'm surprised that we need to add the veeam to the domain

Do you have any feedback about that?

Thanks

Hi Frederic,
to protect Hyper-V clusters (both native and SCVMM-managed) backup server appliance must be joined to a domain.

This info surprised me - is this a requirement for backing up hyper-v clusters? Doing a quick search, i couldn't seem to find anything in particular on that requirement in the user guide/release notes
