Installing DPM System Recovery Tool
[For content updates, see Newly published content for Microsoft System Center Data Protection Manager.]
DPM System Recovery Tool (SRT) can be installed on a DPM server or on a separate server.
When you install DPM SRT, you must specify the location for the primary file store, which will contain the DPM SRT Recovery Points. Ideally, you should locate the primary file store on a disk separate from the disk on which the operating system and DPM SRT are installed. If that is not possible, you can locate the primary file store on a separate volume on the same disk.
The amount of space required by the primary file store depends on the amount of system files you are trying to protect. For example, assume that you are protecting the system volumes of three computers running Windows Server 2003 and the average size of the system volumes is 6 GB. The storage space required would be 6 GB for one computer, and an additional 2 percent to 5 percent of space for each of the other computers. This requirement is because of DPM SRT's storage method, which stores only one copy of any file with a unique content address computed by a 128-bit MD5 cryptographic algorithm.
We recommend that you install DPM SRT on a separate server from the DPM server. However, if you are protecting a small number of computers, (no more than four or five) you can install DPM 2007 and DPM SRT on the same server.
If DPM 2007 and DPM SRT are installed on the same computer, you cannot use that instance of DPM to protect SRT data for disaster recovery scenarios, or vice versa. To protect SRT data using DPM, you must install DPM SRT on a standalone server or on a second DPM server.
