DPM 2012 SP1 - Exchange 2010 Large DB Backup with Large Trunk Files RRS feed

  • Question

  • Hi Guys,

    We are trying to add a new DB into our backups on DPM.

    The DB is around 1.2TB with about 775GB of Logs

    DPM will not back this up, The job will run for a few hours and bombs out with the below.. Errors

    An attempt to prepare the database 'XXXXXXXXXXX' for backup failed because the database is already in the process of being backed up. The error code is -2403. (Note that if a backup was recently aborted, then it may take several minutes for the system to detect the aborted backup and initiate backup cleanup procedures, so this message may be generated if an attempt was made to backup a database before a previous backup attempt had fully terminated.)

    Event ID 9814

    Exchange VSS Writer (instance cacba228-7f71-4257-aca0-74dbfad005ce:1203) failed with error code -2403 when preparing the database engine for backup of database 'Terminated-SDC-2016'.

    Event ID 2007

    Information Store (6368) Shadow copy instance 1203 aborted.

    Event ID 9609

    Exchange VSS Writer (instance cacba228-7f71-4257-aca0-74dbfad005ce:1203) failed with error code -2403 when preparing for Snapshot. 

    Any Idea's ?

    The Above Event ID's are from Exchange, not much in DPM apart from.

    The replica of XXXXXXXXXXX on XXXXXXXXXXXX is inconsistent with the protected data source. All protection activities for data source will fail until the replica is synchronized with consistency check. (ID: 3106)
    Backup failed as another copy of 'XXXXXXXX' database is currently being backed up. (ID: 32628)


    When the does bomb out the protection group shows its only backed up about 1gb.

    i have tried to run a consistency check as well but we get the same issue..

    Thanks for your help!
