  • Question

  • HI Guy's,

    as i was checking the Rollup2 Url again for documentation reasons. ( http://support.microsoft.com/kb/2958100/en-us)

    It now says theres a Bug in RU2:

    Update Rollup 2 for Microsoft System Center 2012 R2 Data Protection Manager is currently unavailable for download because of issues that are related to tape backup and recovery. We have determined the cause of these issues and will release an updated version of this update rollup soon.

    Does Anyone know what exactly is the Problem ?

  • Hi,

    Yes - we have pulled the update from the download center. Let me clarify the issue.  DPM provides the ability to import tapes written from other DPM servers. In case the tape is imported to a different DPM which did not generate the tape, it reads the metadata on the tape and catalogues it for recovery. This capability is referred to as re-cataloguing of the tape. The current issue affects DPM servers that have had re-catalogued tapes at any point in the past in their lifetime. When such a server is upgraded, the issue leads to a crash of the UI/management component of DPM server after installation of the update.  The UI crash happens almost instantly after you re-start the server after applying the update.  Although on going back-up jobs will continue to run, you have no ability to view, monitor or re-try jobs that could have failed.  A significant number of DPM servers have tape devices connected to them and so also re-catalogued tapes for recovery purposes - we felt the incidences of this issue would affect a large number of folks, hence the decision to remove the update till we have it fixed.  We will have an updated patch out there shortly and for those of you that see the UI crash (it will happen almost instantly after you re-start the server after applying the upgrade) please get in touch with Microsoft support and they have some steps to repair your update.
