Replica is inconsistent RRS feed

  • Question

  • We have an Exchange 2010 server being backed up by DPM 2010.  Everything shows as "Ok" for Protection status except for Computer\System Protection\Bare Metal Recovery and Computer\System Protection\System State.  I verified Windows Server Backup is installed on the DPM machine which was a suggestion in a different post.

    We're also receiving this error periodically:

    Status: Inactive
    Volume: NO_PARAM
    Computer: server
    Description: Used disk space on replica volume exceeds threshold of 90%.

    Any ideas?

  • Hi,

    It's a common problem that DPM does not give enought space when protecting BMR workload - and autogrow has some limitations - please review this thread:

  • I'm wondering if it's because Exchange is installed on a >2TB volume.

  • Hi,

     

    Yes, it could be, since DPM relies on windows backup to perform the BMR backup the best way to tell is to run backup manually and see what you end up with on the remote share, then adjust disk space allocation on the DPM server accordingly.

    1) Set up a network share on a remote machine \\server\bmrshare

    2) From an administrative command prompt on the Protected Server, type:

                  wbadmin.exe start backup -allcritical -backuptarget:\\server\bmrshare


    This should show you the list of volumes included in the BMR backup and ask "Do you want to start the backup operation?. - Type Y to continue so you can see how big the resulting backup is on the remote share.   Adjust DPM replica volume for BMR backup accordingly.
