DPM 2012 - System state backup fail due to 2TB+ volume RRS feed

  • Question

  • We have just added a Windows 2008 member server to our network which has a 200GB c:\ volume (for OS/System) and a 8TB d:\ volume (for data). We have installed the DPM agent, added the server to our DPM protection group and wish to protect the new member server. We do not need to protect the 8TB volume, only the system state, bare metal and the system volume. However, the system state backup is failing with a "system state volumes larger than 2088958 cannot be protected" error. It appears the system state believes the 8TB d:\ volume should also be included. Although there is a 'D:\program files' folder it does not include anything critical and is not required should we need to restore.

    How do we amend this to exclude this volume?

  • Hi,

    Yes, most likely the D:\program Files is what is being included in the system writer.

    To identify the offending files and paths, from an administrative command prompt run diskshadow.exe - then list writers.  In the output, look at the files list for the system writer and identify the files that are located on any volume other than the C: volume.

     

    Install this hotfix if applicable: 

     

    980794  System state backup error in Windows Server 2008, in Windows Vista, in Windows 7 and in Windows Server 2008 R2: "Enumeration of the files failed"

    http://support.microsoft.com/default.aspx?scid=kb;EN-US;980794

     

    Then using the information from the list writers output - enter the image paths for the offending files to exclude them from the backup. 

     

    1.

    Click Start , type regedit in the Search programs and files box, and then press ENTER.

    If you are prompted for an administrator password, type the password. If you are prompted for confirmation, provide confirmation.

    2.

    Locate and then click the following registry subkey:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SystemWriter

    Note If this registry subkey does not exist, please create it manually.

    3.

    On the Edit menu, point to New , and then click Multi-String Value .

    4.

    Type ExcludedBinaryPaths , and then press ENTER. Note

    5.

    Right-click ExcludedBinaryPaths , and then click Modify .

    6.

    In the Value data box, type all binary paths that should be excluded from the system state backup operation, and then click OK .

    Note The binary paths should be absolute paths. They should not include environment variables (such as %windir%) and should not be enclosed in double or single quoation marks.

    7.

    Exit Registry Editor.

     To test BMR backup outside of DPM, try this command:

    1) Set up a network share on a remote machine \\server\bmrshare

    2) From an administrative command prompt on the PS, type:

                  wbadmin.exe start backup -allcritical -backuptarget:\\server\bmrshare


    This should show you the list of volumes included in the BMR backup and ask "Do you want to start the backup operation?. - Type N to exit.   Once D: is excluded from the output, then DPM BMR backups will work.
