By supporting deduplication, several new concepts are introduced to Data Protector, including a new device type, the Backup to Disk device, and two interface types - the StoreOnce Software deduplication and the StoreOnce Backup System.

Backup to Disk devices and deduplication are both discussed in detail in this document. Backup to Disk devices are devices that back up data to a physical storage disk and support multi-host configurations. They support different backends such as the StoreOnce Software deduplication or the StoreOnce Backup system. This document also describes the basic principles behind deduplication technology.

A short tutorial is included to guide you through the process of adding a Backup to Disk device, creating a deduplication store, and running a backup session.
