Manage operations on protected computers

Updated: November 1, 2013

Applies To: System Center 2012 - Data Protection Manager, System Center 2012 R2 Data Protection Manager, System Center 2012 SP1 - Data Protection Manager

This topic explains how to handle maintenance actions on computers protected by DPM, including:

Running Windows maintenance tools on protected computers

In general, you can continue maintenance on file servers and workstations protected by System Center 2012 – Data Protection Manager (DPM) using your regular maintenance schedule and the maintenance tools provided in the operating system. Those tools and any impact on data protection are listed in the following table.


Windows Tool Considerations

Disk Cleanup: Use to remove temporary files, Internet cache files, and unnecessary program files.

Running Disk Cleanup should have no adverse affect on performance or data protection.

Disk Defragmenter: Use to analyze volumes for the amount of fragmentation and to defragment volumes.

Before adding a volume to a protection group, check the volume for fragmentation, and if necessary, defragment the volume by using Disk Defragmenter. When protection is applied to extremely fragmented volumes, boot times on the protected computer might be slowed down and protection jobs might fail.

It is recommended that you run Disk Cleanup before running Disk Defragmenter.

Chkdsk.exe: Use to check the file system and file system metadata for errors and to display a status report of its findings.

Before you run chkdsk /f on a protected volume, verify that a consistency check of that volume is not being performed. Running chkdsk /f on a protected volume while a consistency check is being performed on that volume can cause 100% CPU utilization.

Run synchronization with consistency check after running Chkdsk.exe on the protected computer.

Applying updates on protected computers

An important part of computer maintenance is ensuring that operating systems and software are up to date. Updates—known as fixes, patches, service packs and security rollup packages—help to protect computers and data.

You can use your preferred method for deploying software updates, such as Automatic Updates or Windows Server Update Services, on System Center 2012 – Data Protection Manager (DPM) protected computers. Because some software updates require a computer restart, you should schedule or perform the updates at times that have the least impact on protection operations.

Running antivirus software on protected computers

To prevent data corruption of replicas and shadow copies, configure the antivirus software to delete infected files rather than automatically cleaning or quarantining them. Automatic cleaning and quarantining can result in data corruption because these processes cause the antivirus software to modify files, making changes that System Center 2012 – Data Protection Manager (DPM) cannot detect. For information about configuring your antivirus software to delete infected files, see the documentation for your antivirus software.

Changing DPM ports on protected computers

System Center 2012 – Data Protection Manager (DPM) requires ports 5718 and 5719. If these ports are already used by another program, the backup jobs will run, but the recoveries will fail. If it is possible, reassign the ports to DPM. Otherwise, complete the following procedure to change the ports for DPM.

  1. Locate the SetAgentcfg.exe file on the DPM server. By default, the file is located at the following path: %PROGRAMFILES%\Microsoft DPM\DPM\Setup\SetAgentCfg.exe.

  2. Copy the file to the protected computer that is experiencing the problem. Copy the file to the agent DPM\Bin directory. By default, the file is located at the following path: %PROGRAMFILES%\Microsoft Data Protection Manager\DPM\bin.

  3. On the protected computer, open an elevated command prompt, change the directory to where the SetAgentCfg.exe file was copied. For example, %PROGRAMFILES%\Microsoft Data Protection Manager\DPM\bin.

  4. Run the following command to change the ports that are used by the DPM Agent: SetAgentCfg e dpmra <port number> <alternate port number>.

  5. Restart the DPM RA service.
