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.
Note
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.
To configure tape libraries
1. In DPM Administrator Console, on the navigation bar click Management, and then click
the Libraries tab.
2. In the Actions pane, click Rescan.
The Rescan operation might take several minutes to complete. DPM will add any library
jobs to the queue that began during the Rescan operation. If a library job is already in
progress when the Rescan operation begins, the Rescan operation will fail.

Installing and Configuring Protection Agents
A protection agent is software installed on a computer that tracks changes to protected data and
transfers the changes from the protected computer to the System Center Data Protection
Manager (DPM) 2007 server. The protection agent also identifies data on a computer that DPM
can protect and recover.
Before you can start protecting data, you must install a protection agent on each of the computers
that contains data that you want to protect. After the protection agent is installed on a computer,
the computer is listed as an unprotected computer in the Management task area of DPM
Administrator Console. The data sources on the computer are not protected until you add them to
a protection group. Each computer that you want to protect must meet the protected computer
prerequisites. For more information, see Protected Computer Prerequisites
(http://go.microsoft.com/fwlink/?LinkId=100473).
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.
