    Hello,

    I'm using BMR & System State Backup of one physical machine and I just got the following error on one DPM I am managing:

    An unexpected error occurred while the job was running. (ID 104 Details: The process cannot access the file because it is being used by another process (0x80070020))

    The backup on the target system does complete without error if I look in the Windows Server Backup mmc.

    What could be the problem with this backup. I could not really find a solution on the internet.

    Thanks in advance

    Paul

    I get this issue when enable rss and Chimney at DPM server and protected server.

    Chimney

To determine the current status of TCP Chimney Offload: netsh int tcp show global 
To disable chimney: netsh int tcp set global chimney=disabled 
To enable chimney: netsh int tcp set global chimney=enabled



RSS

To determine the current status of RSS, follow these steps: netsh int tcp show global

To disable RSS: netsh int tcp set global rss=disabled 
To enable RSS: netsh int tcp set global rss=enabled
    from http://blogs.technet.com/b/dpm/archive/2012/02/06/data-protection-manager-agent-network-troubleshooting.aspx

    Next i disable rss and chimley AND add DPM server to Administration group at protected server.

    And issue was gone.

    Have a nice day !!!
