Stand Alone HyperV BMR protect guest OS? RRS feed

  • Question

  • So my question is if i have a stand alone HyperV box, and have the full BMR of that machine, are my guests protected? I understand i would not be able to recover them the same way i would the other boxes using DPM but that aside if i restored the HyperV would all the guest essentially work?

  • the bare metal are the body of the host server, but you need to save the hyper-v structure to recover them if you need.

  • Hi JustusIV,

    S.Net is right. BMR will only backup the host server including the C:\ drive by default. If you have other storage on the Hyper-V host containing your virtual machines you will need to included this in protection as well. It would be best if you do a BMR of the host and then protect the Hyper-V virtual guests in DPM. That way you can recover the host and recover the virtual machines in their entirety.

  • Hello,

    There is an exception, if the VHDs were housed on the C: drive then the VHD's will be included with the HyperV host BMR backup. 
    It would have to be quite a bit of space for both the C: and the space allocated in the storage pool for the PG.

  • To add to that DPM MVP Robert Hedblom has a post on adding other drives to be protected as a part of BMR. Here is the link for this: . Doing this will allow you to include other drives in your BMR backup if the VM's are not stored on the C:\ drive.

  • Thanks for the responses.

    I am aware that i would need to include the locations of the vhds for DPM to back them up.

    I was unaware that DPM had special backup proceedures for HyperV. I will read through that whitepaper. 

    Long story short is we have a very complicated standalone hyperv setup all storage is internal. Some of the guest operating systems are not even windows. So thats the main reason why i was wondering how well just an MBR of the host would get a backup of the whole setup.
