SYMPTOMS

After you configure Microsoft System Center Data Protection Manager to help protect the data on one or more file servers, you experience the following symptoms:
  • File servers contain inconsistent replicas.
  • When you use the Data Protection Manager Administrator Console, you notice that data transfer rates may randomly slow.
  • Data replication jobs may fail on one or more file servers. In this situation, job status information that resembles the following is generated on the affected file servers:

    Status message 1
    Type: Consistency check
    Status: Failed
    Description: The DPM service was unable to communicate with the DPM File Agent on server localhost. (ID 52 Details: The specified network name is no longer available (0x80070040))
    Start time: startTime
    Time elapsed: elapsedTime
    Data transferred: 118.51 GB (127253828784 bytes)
    Data transfer rate: 464 KB/s
    Source details: Volume on ServerName
    Protection group members: 7
    Details
    Protection group: ProtectionGroup
    Status message 2
    Type: Synchronization
    Status: Failed
    Description: The replica on the DPM server for Volume on ServerName is inconsistent. Changes cannot be applied to file FilePath. (ID 109 Details: The process cannot access the file because it is being used by another process (0x80070020))
    Start time: startTime
    Time elapsed: elapsedTime
    Data transferred: 1.79 GB (1916715024 bytes)

    Details
    Protection group: ProtectionGroup
    Status message 4
    Type: Synchronization
    Status: Failed
    Description: The replica on the DPM server for Volume on ServerName is inconsistent. Changes cannot be applied to file FilePath. (ID 109 Details: The system cannot find the path specified (0x80070003))

    Protection group members: 2
    Details
    Protection group: ProtectionGroup
    Note You may also receive other job status failure messages.
  • Data Protection Manager synchronization may fail. In this situation, you receive status messages that resemble one of the following:

    Status message 1
    Description: Since date and time., synchronization jobs for path on ServerName have failed. The total number of failed jobs = 4. The last job failed for the following reason: (ID 3115) DPM was not able to complete this job within the time allocated for the set of jobs associated with this protection group. (ID 3151).
    Status message 2
    Type: Synchronization
    Status: Failed
    Description: The replica on the DPM server for path on SERVERNAME is inconsistent. Changes cannot be applied to file path and file name. (ID 109 Details: Access is denied (0x80070005)
    Start time: date and time.
    Time elapsed: elapsedTime
    Data transferred: 18.75 MB (19662648 bytes)
    Data transfer rate: 83 KB/s
    Source details: path on SERVERNAME
    Protection group: Protection Group 1

CAUSE

This problem may occur if the real-time monitoring component of an antivirus program is configured to monitor replicas and to transfer log files for Data Protection Manager 2006 protected volumes. You may experience this problem if the real-time monitoring component of an antivirus program monitors the Msdpmfsagent.exe program on the Data Protection Manager server.

RESOLUTION

For Data Protection Manager 2006

To resolve this problem, configure the antivirus program to exclude real-time monitoring of the Msdpmfsagent.exe program on the Data Protection Manager server. By default, the Msdpmfsagent.exe file is located in the following folder:
%ProgramFiles%\Microsoft Data Protection Manager\DPM\Bin
For more information about how to configure antivirus real-time monitoring based on the name of a process, contact the manufacturer of the antivirus program.
Additionally, if you experience decreased performance when you use the Data Protection Manager 2006 Administrator Console, disable real-time monitoring of the Csc.exe process. By default, the Csc.exe file is located in the following folder:
%windir%\Microsoft.net\Framework\V1.1.4322\Csc.exe
Note The Csc.exe process is the C# compiler. Real-time monitoring of the Csc.exe process can decrease performance in Data Protection Manager 2006 because real-time monitoring of this process causes the antivirus program to scan files that the Csc.exe process generates when the Csc.exe process generates XML messages.

For Data Protection Manager 2007

To resolve this problem, configure the antivirus program to exclude real-time monitoring of the Dpmra.exe program on the Data Protection Manager server. By default, the Dpmra.exe file is located in the following folder:
%ProgramFiles%\Microsoft DPM\DPM\Bin

MORE INFORMATION

Antivirus real-time monitoring of replicas and of transfer log files decreases performance in Data Protection Manager 2006. This behavior occurs because the real-time monitoring process causes the antivirus program to scan the transfer logs every time that Data Protection Manager 2006 synchronizes with the file server. Also, the real-time monitoring process causes the antivirus program to scan all the affected files every time that Data Protection Manager 2006 applies changes to the replicas.

We recommend that you configure the antivirus program to delete infected files from file servers and from the Data Protection Manager server instead of using the quarantine feature to archive infected files. This is to help prevent data corruption of replicas and shadow copies.

If an antivirus program is configured to automatically clean and quarantine an infected file, the antivirus program modifies the file. However, Data Protection Manager 2006 is unable to detect these changes to the file. When Data Protection Manager 2006 tries to synchronize a replica that has been modified by another program, the replica and the shadow copies of the file may be corrupted. For more information about how to configure an antivirus program to delete infected files, see the program documentation, or contact the manufacturer of the antivirus program.
