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 set. 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.
