DPM2010,2008 R2 Clister, 2012 R2 vm RRS feed

  • Question

  • recently came across an issue in an environment where we used DPM 2010 to backup Windows Server 2012 Virtual Machines running on Server 2008R2 Hyper-V cluster. The only option available in DPM for the VM’s was “Backup Using Saved State"

    I’d like to use the online backup option: “Backup Using Child Partition Snapshot”.

    After some digging I found a forum post which had a reply from a Microsoft employee that suggested to create the following registry key:
    HKLM\Software\Microsoft\Windows NT\CurrentVersion\SystemRestore
    REG_DWORD ScopeSnapshots 0x0

    Still not working.

    Im new to DPM and any help will be appreciate.

  • Did you installed the latest updates to your Windows Server 2008 R2 hosts, and then upgrade the integration services inside your Windows Server 2012 R2 VMs ?

  • I don't keep up with DPM that well, but isn't the snapshot option a newer feature that is only available with Hyper-V 2012 or later?

    Since Hyper-V introduced live snapshot merge, that is the feature that enabled the scenario.

  • Hi,

    Protecting Windows Server 2012 VMs with online snapshots you will need at least DPM 2012 with SP1.

    Have a look at the support matrix for further information:
