Updates to DPM are available through Microsoft Update, which is a service from Microsoft that

delivers required updates from the Microsoft Update Catalog. The Microsoft Update Catalog is a

repository for Microsoft software updates and contains updates that address security and

reliability issues. The Microsoft Update service queries the Microsoft Update Catalog to determine

what updates are available for the computer that Microsoft Update is installed on.

You can subscribe to Microsoft Update at any time on the

Running Antivirus Software on the DPM Server

To prevent file conflicts between DPM and antivirus software, on the DPM server, disable real-

time monitoring by the antivirus software of the following directories in the DPM program files:

• \XSD
• \Temp\MTA

DPM is compatible with most popular antivirus software products. However, antivirus products

can affect DPM performance and, if not configured properly, can cause data corruption of replicas

and recovery points. To mitigate these issues, consider taking the following actions:

• Disable real-time monitoring of dpmra.exe on the DPM server.

To minimize performance degradation, disable antivirus real-time monitoring of replicas and

transfer logs for all protected volumes by disabling real-time monitoring of the DPM process

dpmra.exe, which is located in the folder Program Files\Microsoft Data Protection

Manager\DPM\bin.

Real-time monitoring of replicas degrades performance because it causes the antivirus

software to scan the replicas each time DPM synchronizes with the protected server and to

scan all affected files each time DPM applies changes to the replicas. The problem is

resolved when you disable the feature for the replicas. For information about configuring real-

time monitoring based on process name, see your antivirus product documentation.

• Disable real-time monitoring of csc.exe on the DPM server.

If you experience degraded performance while using DPM Administrator Console, disable

real-time monitoring of the csc.exe process, which is located in the folder

Windows\Microsoft.net\Framework\v2.0.50727\csc.exe. The csc.exe process is the C#

compiler. Real-time monitoring of the csc.exe process can degrade performance because it

causes the antivirus software to scan files that the csc.exe process emits when it generates

XML messages. For information about configuring real-time monitoring based on process

name, see your antivirus product documentation.

• Delete infected files on protected servers and the DPM server.
