DPM 2016 UR2 BMR to Tape RRS feed

  • Question

  • Greetings!

    We have two physical DPM 2016 UR2 servers with local hardware RAID-controller with 9 TB of ReFS disk each, and HP MSL 2024 Library.

    Each DPM server makes Bare Metal Backup of another one with the following schedule:

    - Disk Backup:

    Daily, at 02:00;

    - Tape Backup:

    Weekly, every saturday at 04:00.

    DPM-2 Server backups DPM-1 server without any problems.

    But we have a trouble with DPM-02 backups from DPM-01 server.

    After creating New Protection group, disk BMR-backup of DPM-02 finished successfull. Two or three times. 

    Then we got error:
    DPM cannot create a backup because Windows Server Backup (WSB) on the protected computer encountered an error (WSB Event ID: 517, WSB Error Code:  0x4164AD30). (ID 30229 Details: Internal error code: 0x80990ED0)


    The backup operation that started at '‎2017‎-‎07‎-‎10T12:12:52.129702100Z' has failed with following error code '0x8078015B' (Windows Backup encountered an error when accessing the remote shared folder. Please retry the operation after making sure that the remote shared folder is available and accessible.).

    If we try to run Consistency check a few times, then it may finish successfully with creation of new recovery point.

    But if we try to run Tape BMR-backup of DPM-02 server, then it quickly failed with error: 

    Description: Backup to tape failed.

    DPM encountered an error while performing an operation for C:\WindowsImageBackup\ on DPM-01.domain.local

    There is a lot of free space on C:\ drive. We try to change backup letter in PSDataSourceConfig.xml, but without any changes.

    N.B.: We have similar groups with BMR of 2008R2 servers (AD DS) without problems on each DPM server.

    Any suggestions?
