- Microsoft System Center Data Protection Manager 2006
After you configure Microsoft System Center Data Protection Manager 2006 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
Status message 2
Status message 3
Status message 4Note 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
Status message 2
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.
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:
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.
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.
