THE NEED:

In DPM you may run into scenarios where you are backing up a folder or a volume and there are folders or sub-folders that you actually don’t need  or want to protect. There is a way to “exclude” these from the backup. Before we talk about how to do this lets look at an example of why you would want to do this.

THE EXAMPLE:

Lets say you have a Windows cluster and you are backing up the c volume on one of your nodes in the cluster. This cluster is a Hyper-V cluster and you are protecting the virtual machines in your cluster directly. The C:\ClusterStorage folder on the c volume is where your .VHD’s and other virtual machine data is stored. You do not want to backup this folder because the virtual machines are being protected directly by DPM but you want to continue protecting everything else on the c volume. This is where  being able to exclude the C:\ClusterStorage folder comes into play.

THE SOLUTION:

Here is how you can exclude something from being backed up by DPM. There is a registry key on Windows servers called “FilesNotToBackup”. This key needs to be modified on the protected server with the data you want to exclude from the backup. It is that simple. Now here is how you do this.

Make a registry entry to the FilesNotToBackup list in the registry on the protected server you want to exclude data on.                         DPM/VSS will honor the FileNotToBackup list.

The path is: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBackup add a Multi-String (REG_MULTI_SZ) value and place something like: C:\ClusterStorage (or any data you want to exclude from backup) in the Value Data field.

The next time the data is protected it should skip the C:\ClusterStorage (or any data you have selected to exclude from backup).

DPM’s data protection is facilitated by the Volume Shadow Copy Service (VSS). Therefore VSS is the secret sauce. VSS is in OS’s and Microsoft applications such as Exchange, SharePoint, and Hyper-V have their own VSS writers. Yes this may be old news as the VSS technology  has been around for some time but many IT Professionals still do not have a good understanding of VSS itself.

It is important for anyone working with DPM and even many other backup products out there to get a good understanding of VSS to know how the data protection is working underneath the hood. Microsoft has some  really good sites that explain VSS well. As a data protection protection pro it is important to go through these and become familiar with how VSS works:

DPM 2012 Beta is out. One of the new features of DPM 2012 is that you can install the DPM Administrator Console on other servers or workstations and manage your DPM 2012 and even DPM 2010 servers remotely without having to logon to the DPM server. The cool part is that you can manage existing DPM 2010 servers. This is done through applying a hotfix to your DPM 2010 server and installing the console on your workstation or server from the DPM 2012 beta software.

In this blog post we are going to walk through setting this up. It is a simple two step install installing the hotfix on the DPM 2010 server first and then the console on the workstation. Here is the process:

First download the DPM 2010 Interoperability patch for DPM 2012 Beta hotfix (DataProtectionManager2010-KB2581742) and DPM 2012 Beta.

• DPM 2010 hotfix: http://support.microsoft.com/kb/2581742
• DPM 2012 Beta: http://www.microsoft.com/download/en/details.aspx?id=27216

Copy the DPM 2010 Interoperability patch hotfix for DPM 2012 Beta  to your DPM 2010 server.

Make sure your DPM 2010 is all up to date. Once DPM 2010 is up to date install the beta hotfix.

Open up DPM 2010 after the hotfix and verify it is still working.

Now the DPM 2010 server is ready lets install the console on the client machine.

Here are the steps:

Navigate to the DPM 2012 Beta install and chose 32 or 64Bit depending on what your workstation is.

Launch the DPM 2012 Beta install on your local workstation.

Select “DPM Central Console” to begin.

I recently ran across a thread on DPM TechNet forums with a topic on how to access DPM alerts.   They wanted to monitor DPM errors and events. You can use a third party tool to do this or you can use System Center Operations Manager/Essentials .

If you have the option to use System Center to monitor your DPM I recommend this as it does work pretty well. In my environment I  use System Center Essentials 2010 to monitor DPM alerts. The first step to monitoring your DPM server is to make sure you publish the DPM alerts to the Windows Event Viewer. To do this follow these steps:

1. Go to the DPM Administrator console
2. Click on “Action” on the top bar in DPM
3. Select “Options”
4. Click the “Alert Publishing” tab
5. Click the “Publish Active Alerts” button
6. Click ok

This will send your DPM alerts to the Windows Event viewer on your server and either SCOM/SCE can access them from there or a third party systems monitoring tool. You will find the alerts in Windows Event viewer under “Applications and Service Logs”. You will see “DPM Alerts” and “DPM backup Events” (Note: if you want backup alerts you need to publish them as well) listed here.
