Constant "Replica is inconsistent" errors - ID 112 "Cannot create a file when that file already exists" RRS feed

  • Question

  • DPM2010, trying to BMR back up a XenApp6 server with Sophos antivirus running on it. I'm getting constant "Replica is inconsistent" errors with the following in the details:

    Changes for Volume C:\ on <servername> cannot be applied to \\?\Volume{ef124e7c-a496-11df-8b1e-806e6f6e6963}\ProgramData\Sophos\AutoUpdate\Cache\savxp\. (ID 112 Details: Cannot create a file when that file already exists (0x800700B7))

    From Google it appears as if this is a problem with the local Windows backup service that DPM is initiating, but I don't see any way to check on this on the protected server.

    Any ideas as to what's really going on?

  • I'd start by checking the event viewer on the protected computer to see if you are getting any additional VDS or VSS Writer errors.
    Are you able to create a snapshot on the volume manually?

    I've seen a situation where A/V software will lock file access to the DPM Agent (A/V usually uses filter drivers to the filesystem for this). You might want to make sure you have antivirus exceptions for DPM as per http://technet.microsoft.com/en-us/library/bb808691.aspx

  • Did you find a resolution to this? I am experiencing the exact same issue. Inconsistent replicas and the path pointing to the Sophos Auto Update directory just like you're experiencing. What did you find? J

  • Hi,

    Make sure the System account has full permissions on C:\System Volume Information and all subfolders and files.

    Try running the following command on the protected server:

    WBADMIN START SYSTEMSTATEBACKUP -BACKUPTARGET:C:

    If this fails, check the Sytem event log and the Microsoft-Windows-Backup event log for errors and/or warnings.

    Thanks,

    Marc

  • Does DPM take backup for system state and C: or it fails also?

    Laith.

  • just the backup of c: fails. the system state and bare metal complete fine - as do other partitions.

  • In the C: backup of the server can you add an exclusion in for the folder \ProgramData\Sophos\AutoUpdate\Cache\savxp\ and see if the backup can complete?

    Maybe also run a chkdsk on the volume (obviously need a reboot given it is on C:) and see if that helps.

  • Hi ZackinMA,

    Can you check why the C fails?

    If it fails because of reading some files then execulde these files and run the backup for the C again.

    Take into consideration to create two different PG for both system state and C and run them in two different time and make sure that each one must be finish while the other one will begin.

     

    Hope that helps.

    Laith.

  • It ended up being my antivirus's cache folder causing the problem. i excluded it from the backup of the C: for every member of the protection group and I'm off and running.

    Now I'm not sure why that particular folder was causing a problem, but excluding it did fix it. It was c:\program data\sophos\autoupdate\cache that I had to exclude.

  • excluding the sophos cache fixed the issue for me as well.
