Windows Server Backup & Hyper-V Host Component

    Question

  • Because I was having inconsistent backups use the Child Partition Snapshots, I have each of my VM's doing their own backup. So I an preparing a custom backup schedule for the actual server, excluding the VM's. Should I back up the VM Host Component?

  • Yes . Make sure you take system state backup using this method you can take backup of VM Host Components.

  • Hi,

    Host Components:

    It is mandatory to have host component while taking backup of VM using DPM 2010/2012. If we failed to take the backup of HOST COMPONENT we might failed to Recover Virtual Machine with the same configuration using recovery types of “Recover to the original instance / Recover as virtual machine to any host“ . Your virtual machine will not restart on any host without host component. In simple words: host components carrying virtual machines configuration files.  

    Note: Backup of virtual machine without host components also can recoverable but we will miss the configuration part. We have to re-configure each and everything to make VM active.

     Regards,

    That's not a bad suggestion, but what if I create multiple protection groups for different sets of VMs? In this case, DPM will only let me add the host component to just one the PGs.

    "This item is already a member of another protection group."

    Should I create a separate PG just for the host components of the Hyper-V hosts and make sure it runs whenever any of the other Hyper-V-related PGs run?
