Recovering Data from Tapes
Recovering Data from Tapes Created by Another DPM Server
To recover data from tapes created by another DPM server, such as when a DPM server fails
and critical information must be recovered before the server can be restored, you must first
physically add the tape to a DPM server and then use the Recatalog imported tape action.
During the recatalog operation, DPM reads from the tape and adds information about the data it
contains to the database. After recatalog completes, you can recover data from the tape by
selecting a recovery point from the data on the tape.
Recovering Data When a Tape Set Is Missing a Tape
When protected data, such as a volume or a SQL Server database, spans multiple tapes, all
tapes from the tape set must be available for DPM to recover the data. When a tape from a tape
set is missing, perform the following steps to access the remaining data:
1. Add the tape to the tape . You might need to recatalog the tape.
2. View the contents of the tape.
3. Copy the contents of the tape to the desired location.
After you copy the contents of the remaining tapes, you can use the copied data as you like.

Disaster Recovery
Using Microsoft System Center Data Protection Manager 2007 (DPM) in your organization
enables you to protect file and application data, and provides fast and efficient recovery of that
data when the original data is lost or corrupted or mistakenly deleted. But what if the entire data
center with all your critical servers is partially or completely destroyed? Or if the DPM server that
is protecting the data is damaged or fails?
Disaster recovery refers to restoring your systems and data in the event of partial or complete
failure of a computer because of natural or technical causes. This section explains how to
prepare for disaster recovery and how to rebuild protected servers and the DPM server when
