  • Hi YoniB,

    Answer is Yes => During DPM uninstallation, On the Uninstallation Options page, click Retain disk-based recovery points.

    Check theses 2 links before doing anything:

  • Thanks for the links, but none of them mentions reinstalling Windows.  What I am concerned about is that VSS information is lost when I reinstall Windows, and possibly losing recovery points with that.

  • YoniB,

    As long as you have a backup of DPM database and choose to Retain disk-based recovery points during DPM uninstallation you will able to recover your DPM and Datas.

    You may follow theses steps:

    1. Back up the DPM database.
    2. Uninstall DPM. (Retain disk-based recovery points)
    3. Install fresh OS (Same DPM name / Same domaine as before).
    4. Reinstall DPM.
    5. Restore the DPM database.

  • Hello,

    There are three main things that are overlooked when doing this.

    a.) The storage pool needs to be left alone.
    b.) The DPM server name needs to be the same in order to make the correct associations when synching the DPM database restore.
    c.) When you re-install DPM make sure its the same DPM version. Example: If it was 7706 when you created the DPM backup, then you need to re-install it and bring it up to that same version before performing a dpmsync.

  • i concur with ShaneB. I have had to recover from a catastrophic failure and pretty much came back up without any major issues with all disk based recovery points working fine. Read the kb articles on db restore and all will be well.

    Link above applies to DPM 2007 but worked for DPM 2010. I cannot remember if i found one for 2010 but steps i believe are identical.
