How to deploy a Data Protection Manager 2007 agent in Exchange Server

The first step to protect Exchange Server is to create one or more storage pools -- groups of disks that can be used for backups. Learn how to create a storage pool using Microsoft's Data Protection Manager (DPM) 2007 and then add a disk to that storage pool. You'll also get an understanding of DPM's licensing structure.

The first step in protecting Exchange Server is to create one or more storage pools, which are groups of disks that can be used for backups. In this tip, you'll learn how to create a storage pool using Microsoft's Data Protection Manager (DPM) 2007 and how to add a disk to the storage pool. You'll also get an understanding of DPM's licensing structure.

To create a storage pool, open DPM 2007's Administrator console and click on the Management tab. Three additional tabs will appear beneath the top row of tabs. Select the Disks tab, and you will see that there are no disks in the storage pool.

To add a disk to the storage pool, click Add. You'll then see a list of all of the disks in the system, in addition to the system disk.

On this screen, notice how Data Protection Manager looks at volumes, rather than individual disks. For example, Disk 3 is a RAID 5 volume, but is displayed as a single disk (see Figure 1).

Additionally, if any data exists on a disk, that data will be preserved. I recommend removing any volumes from the disks before adding them to the storage pool. This way, you can work with the disk's full capacity.

After you've decided which disks to add to the storage pool, select the disk and then click Add. You can add as many disks as you want. Click OK when you're done. If you've added any basic disks to the pool, you will see a warning message telling you that the disks will be converted to simple volumes.

After creating a storage pool, you must deploy agents to the servers that you want to protect. Figure 1 shows an Agents tab to the left of the Disks tab. Click the Agents tab and you should see that no agents are installed.

Before you can deploy any agents, you must inform DPM how many licenses you have purchased. To do so, click the Update DPM Licenses link found in the Actions pane. Windows will then display the Update DPM Licenses dialog box, shown in Figure 2.

There are two different types of licenses listed: standard and enterprise. Standard licenses let you back up data files and a server's system state. These licenses are primarily suitable for file servers, domain controllers and other types of servers that don't require a specialized backup. Enterprise licenses, on the other hand, are used to back up application servers such as Exchange Server.

After entering your license count, click OK.

To deploy the agents, click the Install link found in the Actions pane. You will see a screen that displays all of the computers located in the current domain. Choose the computers you want to protect and click Add. When you're done, click Next.

Windows will prompt you to enter a set of credentials that can be used to deploy the agent on the target servers. After entering this information, click Next. A message appears informing you that the servers you have selected must be rebooted after the agents are installed. You can either reboot the servers automatically or reboot them manually. Make your choice and click Next, then Install.
