As the latest member of the Windows Server System family, Data Protection Manager (DPM) is a server software application that optimizes disk-based backup and recovery. Backing up data to disk provides the fastest way to recover data lost because of user error or software and hardware corruption. With DPM, recovering information is as simple as browsing a share and copying directly from to the production server.DPM lets IT administrators easily and affordably use existing Windows Server investments such as Active Directory, Microsoft Windows Server 2003, and Microsoft Windows Storage Server 2003.DPM provides rapid and reliable recovery of data lost because of user error or server hardware failure. DPM uses efficient byte-level replication to deliver faster backup and less potential data loss. DPM lowers the total cost of your data protection environment by improving the efficiency of your operations.
