Updated: November 1, 2008

Applies To: System Center Data Protection Manager 2007

Compressing data for tape can result in significant savings in time, hardware, and performance. By compressing data, you are able to put more data on tape and use fewer tape drives. DPM supports compressing data in protection groups on tape for long-term and short-term protection. The following procedure shows you how to compress data in a protection group.

noteNote
DPM does not support compression if you choose to encrypt data in a protection group.

  1. In DPM Administrator Console, click Protection on the navigation bar.

  2. On the Actions menu, click Create protection group. This starts the Create New Protection Group Wizard.
