The storage pool is a set of disks on which the Data Protection Manager (DPM) server stores replicas and recovery points. Before you can start protecting data, you must add at least one disk to the storage pool. Disks added to the storage pool should be empty. To prepare disks for data protection, DPM reformats the disks and erases any data on them.

The DPM server must have at least two disks installed: one dedicated to the startup, system, and DPM installation files; and one dedicated to the storage pool. In the context of DPM, disk is defined as any disk device manifested as a disk in the Windows Disk Management tool. DPM does not add any disk containing startup files, system files, or any component of the DPM installation to the storage pool.

DPM does not support USB/1394 disks.

For information about choosing disk types and calculating capacity requirements for your storage pool, in the DPM 2007 Deployment Guide, see Planning for DPM Deployment (
