Virtualization: HYPER-V & DPM 2010 ITEM LEVEL RECOVERY


With the release of Data Protection Manager 2010, DPM adds significant scalability, reliability, and manageability enhancements such as:

• Up to 100 servers, 1000 laptops, or 2000 databases protected by a single DPM server

• Significant auto-protection, auto-healing, and reduced alerting for a more “fire and forget” experience

• Enhanced disaster recovery options for long-distance data protection and business continuity initiatives

Of course DPM 2010 offers key new capabilities when used with Hyper-V R2 such as:

• Protection of Live Migration-enabled servers running on CSV in Hyper-V R2

• Flexibility to protect virtual machines from Windows guests or from the hypervisor host

• Ability to restore virtual machines to an alternative host

• Host-based backups will now enable item level recovery (ILR) from within the VHD

I’d like to focus on the last item, Item Level Recovery. Item Level Recovery is an aptly titled feature that allows you to restore individual items. However, this very powerful feature is subtly hidden right in front of you so I thought it would be good to point this out. A few of us spent a long time looking for this feature before consulting the DPM team… J


DPM 2010: Item Level Recovery


To access DPM 2010 Item Level Recovery…

1. Launch DPM 2010

2. Select Recovery

3. Under the Recoverable Data, select the VM from which you wish to recover data

4. Choose the date and time for a point in time recovery

5. Under Recoverable Item is where Item Level Recovery is located (this is where the magic happens…)

a. If you right-click on this item, you’ll be presented with the Recovery dialog. The Recovery dialog will step you through restoring the entire backup, not the Item Level Recovery.

b. To reach the Item Level Recovery, DOUBLE-CLICK on the Recoverable Item and wait a few seconds. You will then be presented with a list of available files for recovery. Alternatively, you can search to find a specific file for recovery.

Once you know the trick (double-clicking on the recoverable item for ILR) you’re good, but it’s not easily discoverable and this functionality is very powerful. So powerful that you don’t want to miss it and you’ll want to show this to customers. Finally, we’ve spoken with the DPM team and they’re looking at ways to make this feature more discoverable. J

  1. Non supported workaround is to use ocsetup to install the role

  2. Harry Falkenmire says:

    Very important to note, and a huge #fail on an otherwise amazing product, that VHD item level restore requires the Hyper-V role installed on DPM server. Big deal, i hear you say, until you find that you cannot install the Hyper-V role on a Hyper-V guest, which means you can't virtualize your DPM server AND have VHD ILR. Which sucks. A lot. Fix this!

  3. femi says:

    how is ocsetup a workaround?

    The fact is you can't install Hyper-V role on a Hyper-V guest, therefore, if you "virtualize" your DPM server, you can not do vhd ILR!

  4. Dan_IT says:

    You *can* install the role but it will fail to start any guests assigned to it as it can't access the ED bit nor the  virtual extensions on the processor

    Just wanted to say thanks, I had read that DPM 2012 should be able to do Hyper-V ILR in my scenario but I could not for the life of me figure out how to access it. I guess I tried right clicking and hunting in the UI but didn't think to double click. They could at least add it to the right click context menu!

    Appreciate it 😉

  6. Jaro says:

    You can install Hyper-V inside VM (running on Hyper-V). As with many Microsoft products if GUI doesn’t work use powershell: Enable-WindowsOptionalFeature –Online -FeatureName Microsoft-Hyper-V –All -NoRestart

    This will install Hyper-V.

    Even having that installed I am still unable to do ILR "simply by double-clicking vhdx".

    But still getting:
    DPM cannot browse the contents of the virtual machine on the protected computer .com Item level recovery is not supported in the following scenarios.
    1. The VHD contains a dynamic disk inside the guest OS.
    2. The VHD has no volume.
    3. HyperV role is not installed on DPM server.
    4. Automatic mounting of volumes is disabled on the DPM server.

    1) Try enabling automatic mounting of volumes using mountvol on the DPM server to preform item level recovery.
    2) Otherwise perform a full restore of the virtual machine.
