• Adding a disk to the storage pool is not a requirement if you are going to use custom
volumes to protect your data sources or if you are going to use disk-to-tape protection
only.
• DPM cannot use space in any pre-existing volumes on disks added to the storage pool.
Although a pre-existing volume on a storage pool disk might have free space, DPM can
use only space in volumes that it creates. To make the entire disk space available to the
storage pool, delete any existing volumes on the disk, and then add the disk to the
storage pool.
• Configure tape libraries and stand-alone tape drives if you want to protect data on tape.
• Install a protection agent on each computer that you want to protect.
• Start and configure the Windows SharePoint Services VSS Writer Service (WSS Writer
service), and provide farm administration credentials for the protection agent.
• Perform this task only if you are protecting server farms on servers running Windows
SharePoint Services 3.0 or Microsoft Office SharePoint Server 2007.
• Create one or more protection groups.
Configuring Tape Libraries
• You use the Rescan operation on the Libraries tab to check for and refresh the state of all
new tape libraries and stand-alone tape drives when you make changes to your hardware.
If the stand-alone tape drives listed on the Libraries tab in DPM Administrator Console do
not match the physical state of your stand-alone tape drives, in the DPM 2007 Operations
Guide see Managing Tape Libraries (http://go.microsoft.com/fwlink/?LinkId=91964). For
example, if drives from a tape library are listed as stand-alone tape drives, or if a stand-alone
tape drive displays incorrectly as a drive in a tape library, you need to remap the tape drive
information.
Installing and Configuring Protection Agents
• DPM supports protecting computers across domains within a forest; however, you must
establish a two-way trust across the domains. If there is not a two-way trust across domains,
you must have a separate DPM server for each domain. DPM 2007 does not support
protection across forests.
If a firewall is enabled on the DPM server, you must configure the firewall on the DPM server.
To configure a firewall on a DPM server, you must open port 135 to Transmission Control
Protocol (TCP) traffic, and you must enable the DPM service (Msdpm.exe) and the protection
agent (Dpmra.exe) to communicate through the firewall.
Configuring Windows Firewall on the DPM Server
• If Windows Firewall is enabled on the DPM server when you install DPM, DPM Setup
configures the firewall automatically.
