After upgrading to v13, all our Hyper-V backups stopped working. I understand there was a change in the way SCVMM is used in v13. I found out I was unable to deploy the Veeam components to SCVMM because we are using an HA cluster. Trying to deploy the components on the existing SCVMM record didn't work because it's a cluster name, not a server and the admin$ share doesn't exist. I did open a case (08097273) but support didn't seem to understand my issue. I was able to get it working by adding each individual SCVMM cluster node as a general Windows server.
There doesn't appear to be anything in the documentation on how to add an SCVMM cluster to Veeam in v13, so is this the correct way to add an SCVMM cluster?
The only reference I found to an HA SCVMM install is this note about VSA:
[Microsoft Hyper-V only] Linux-based Veeam Software Appliance does not support the SCVMM High Availability feature.
What exactly is the reason for this limitation? Does this mean I can't migrate to VSA in the future?
I clarified internally - User's Guide is accurate - Veeam Software Appliance does not support adding SCVMM clusters, this is due to architectural limitation as of now.
We can't commit to a timeline for adding it, but it's on our radar and may appear in future releases. I must also let you know, we haven't heard such requests before, so I'd love to hear other customers with similar requirements in this thread.
Veeam Backup & Replication for Windows does support SCVMM HA clusters starting v13.0.2, where you don't need to install any components to the cluster nodes directly, instead the special service is installed on the VBR server itself - so that's the way to go for now. (if you decide to go that way, please ask your support engineer about SCVMMUseLocalPSManager registry key - they have that information)
One thing to avoid: please don't add one or several individual SCVMM cluster nodes to the inventory from the same cluster. That setup isn't supported.
You may also consider adding your HV workloads (HA clusters or standalone nodes) directly to the inventory, bypassing SCVMM entirely. That is supported on Veeam Software Appliance.
In such case the only thing you will be missing is support of SCVMM tags in the jobs.
