Specifying Tape and Library Details
If you select protection using tape, you must specify the number of copies of each tape that DPM
should create and the configuration options for the backup tapes. You can choose one of the
following options:
• Compress data
If you select this option, DPM compresses the data as it is written to the tape, which reduces
the space needed on the tape and increases the number of backup jobs that can be stored
on the same tape. Compression does not significantly increase the time required to complete
the backup job. The rate of compression varies according to the type of data.
• Encrypt data
If you select this option, DPM encrypts the data as it is written to the tape, which increases
the security for archived data. Encryption does not significantly increase the time required to
complete the backup job.
Note
To enable encryption, a valid encryption certificate must be available on the DPM
server. For instructions, see "How to Encrypt Data in a Protection Group" in DPM
Help.

Choosing a Replica Creation Method
When you create a protection group, you must choose a method for creating the replicas for the
volumes included in the group. Replica creation involves copying all the data selected for
protection to the DPM server and then running synchronization with consistency check for each of
the replicas.
DPM can create the replicas automatically over the network, or you can create the replicas
manually by restoring the data from removable media such as tape. Automatic replica creation is
