Not getting option to Backup Using Child Partition Snapshot DPM 2012 R2 RRS feed

  • Question

  • I am running DPM 2012 R2 fully patched.

    I am trying to use Backup Using Child Partition Snapshot of a Hyper-V Server 2012 R2 Datacenter Cluster using CSV.

    I get no option to use Backup Using Child Partition Snapshot, just online backup.

    I have gone through the steps in the Microsoft document "Configure CSV Backups" (Some steps did not apply due to my not using Windows 2008 R2)

    Has "Backup Using Child Partiton Snapshot" been replaced by "\Online\VMName" ?

    What am I missing?

  • Hi,

    Yes, Windows server 2012 R2 has changed the caption from "Backup Using Child Partiton Snapshot" to "\Online\VMName" - DPM is displaying the new caption when protecting Windows Server 2012 R2 guests.


    To list Windows 2012 R2 hyper-V writer captions for guests to see if online or offline state backups will be done:

    From an administrative command prompt on the Hyper-V server:

    a. Type: copy con script.txt and press enter
     b. Type: list writers and press enter
     c. Press CTRL + Z + enter (to save)
     d. Type: diskshadow /s script.txt | find /i "caption: O"

    Output will be displayed for each guest as follows.

    C:\temp>diskshadow /s script.txt | find /i "caption: O"
                            - Caption: Online\SQLSERVER
                            - Caption: Offline\WSS-V14

    The Windows 2012 R2 Hyper-V writer adds the VM in the following format:

     For offline backups: Offline\<VMName>
     For online  backups: Online\<VMName>
