DAG Required for DPM Backup of Exchange?? RRS feed

  • Question

  • I have setup DPM 2012 and am now backing up all my physical and virtual machines.  I went to do a test restore of an Exchange mailbox today, only to find that it is NOT backing up the Exchange components.  The Hyper-V node is backed up, but it is not recognizing it as an Exchange server.  After researching this I copied the ese.dll and eseutil.exe files from the Exchange server to the DPM/bin folder and rebooted, but the protection group still doesn't see Exchange.  I found information on-line that states DPM will only backup Exchange if it is in a DAG.  Is this true??  Do I have to go buy another Exchange server license just to get DPM to backup Exchange??

    Are you saying that a hyper-V host has Exchange installed on it ?

    That is not a correct statement - please provide a link to that content.

    In any case, no data source is backed up "automatically" - you need to expand the exchange server and select the exchange database you want to protect.  The red box outlines a standalone exchange 2010 server.  Right above that is an exchange DAG so you can see the difference.  DPM can protect both.

  • Hi,

    Yes, if you want application backups like Exchange or SQL that run inside the Virtual machine, you must install the DPM agent inside the guest.  That guest will then appear as a physical server for you to expand and select the Exchange DB to protect.

    Since both Hyper-V and exchange backups will cause logs to be truncated, you must add this registry key inside the exchange server so hyper-V backups will not truncate logs and allow DPM exchange backups to work properly.

    Location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Virtualization\VssRequestor
    Name: BackupType
    Type: REG_DWORD
    Value: 1

  • Thanks for the reply.  I'll look for that post about the DAG comment next time at that site.

    You are correct that the Exchange Server is a Hyper-V Guest.

    I'm not being presented with the option to select the individual server.  I went back and forth with MS on this before pulling the trigger on the DPM purchase.  I have the DPM agent installed only on the physical host, which I was assurred gave me the ability to back both the VHD files and the server as a separate entity.  Is the problem that I don't have an agent installed on the Exchange VM?  When I modify the protection group and expand the physical host, here is what I see:
