Protect Hyper-V Cluster without VMM

    Question

  • In the past I have been trying to protect a Hyper-V cluster with DPM 2012 and 2016 but the backup jobs were failing continuously. I suppose this could be due to live migration that has been executed from time to time. Then I read this article which states that in order for DPM to maintain protection within a cluster, VMM must be used. Is this correct? I don't have VMM but would like to protect the VMs somehow, what is the recommended method in this case?

  • DPM seamlessly protects live migrating VMs on CSV (cluster shared volume) clusters, but for this to work well the storage hardware must support VSS.

    Without the VSS support, DPM can only backup through the node that “owns” the CSV storage. Either way, the VM is backed up regardless of which node in the cluster hosts the VM.

  • Hello Yordan,

    Yes in order to maintain protection during live migrations then you will need SCVMM.

    It is not a requirement to have SCVMM to be able to protect virtual machines (VMs) on a Hyper-V cluster.

    If you do a lot of migrations, then it would probably be better to use SCVMM, if you're going to use DPM for backing up VMs, you should also have access to SCVMM as it's in the same System Center suite. But remember that there are two licensing versions Standard and Datacenter for System Center.

    Best regards,
    Leon

  • Thanks for your reply. So, is there something specific in protecting VMs on a Hyper-V Cluster? For example, I need to do live migrations every month, actually the Cluster-Aware Updating rules are triggering it to update the hosts. Will DPM continue to protect the VMs (and not fail with inconsistency) after the VMs have changed their current owner?

  • Yes, thank you, I will consider the information when configuring the protection groups in the future.
