This document describes how Data Protection Manager (DPM) works to backup and restore data. DPM protects production data by replicating it to DPM replicas and storing recovery point areas up to every 15 minutes. The diagrams show how DPM captures changes to production data over time at different recovery points, allowing restoration of previous versions of data.
