Creating a protection group is the final step in configuring Microsoft's Data Protection Manager (DPM) 2007 in Exchange Server. This tip from Exchange Server expert Brien Posey offers you the steps involved in creating a protection group, including whether to establish short-term or long-term protection and how to determine your storage goals when configuring DPM 2007.
When creating a protection group, there are specific items that you'll want to protect. After choosing these items, click Next. When you do, DPM 2007 will prompt you to enter a protection group name. You can go with the default name of Protection Group 1, but I recommend using a name that describes the group's purpose.
Depending on how your server is configured, you may be given the option to choose between short-term or long-term protection. Short-term protection writes data to a disk, while long-term protection writes data to tape. However, the long-term protection option won't be available unless your server contains a tape drive (Figure 1).
Click Next and you'll see a screen that asks if you want to use ESEUTIL to perform data integrity checks of your Exchange Server database. If you're using disk-based protection, ESEUTIL will run directly on the DPM 2007 server. If you are using tape-based protection, ESEUTIL will run on the Exchange server.
Before you continue, you should know that ESEUTIL and the supporting DLL file are not automatically installed on the DPM 2007 server. Using ESEUTIL on the DPM server is recommended, but this will require you to install Exchange Management Tools on your DPM 2007 server.
Note: The version of ESEUTIL that you deploy must match the highest version of Exchange Server that's deployed on your network. Keep in mind that ESEUTIL is updated with each service pack. Therefore, if the highest version of Exchange running on your network is Exchange Server 2003 SP2, you'll need to install the SP2 version of the Exchange Server 2003 management tools.
This is also true with Exchange Server 2007, which is a 64-bit application. DPM 2007 is available in both 64-bit and 32-bit. If you're running the 32-bit version of DPM 2007, you can download the 32-bit version of the Exchange 2007 management tools. This page contains both the RTM and SP1 versions of the management tools. You must use the version that corresponds to the highest version of Exchange installed on your network.
It's also important to remember that Exchange Management Tools must be kept current. If you install a new service pack for Exchange Server at a later date, you have to update the management tools on DPM 2007.
After you've installed the Exchange Server Management Tools, copy the ESE.dll and ESEUTIL.exe files from c:\Program Files\Microsoft\Exchange Server\Bin to c:\Program Files\Microsoft DPM\DPM\bin\.
Once these files are in place, click Next. The wizard will display the Specify Short Term Goals screen. This screen allows you to specify the data retention period and the synchronization frequency. You can also choose a specific time period for recovery points and for the express full backup (Figure 2).
Click Next and you will be taken to the Review Disk Allocation screen. Here, DPM 2007 calculates how much disk space you need based on the size of each object you're protecting. You can click the Modify button if you want to adjust disk space allocation. In many cases, though, the default allocation is fine.
When you're done, click Next and DPM 2007 will prompt you to set up a schedule to create the initial replicas. You can instruct DPM 2007 to create replicas now, to create them at a specific time or that you want to create the replicas manually.
After making your selection, click Next and you'll see a summary of the settings that you've chosen. If everything looks correct, click Create Group and DPM 2007 will create the protection group.
