DPM is provides an efficient disk-based data protection and recovery solution. DPM protects Microsoft® Windows® 2000 Server, Microsoft Windows Server 2003, and Windows Storage Server 2003, and makes use of advanced features such as replication, policy-driven protection, and the Windows Server 2003 Volume Shadow Copy Service (VSS). DPM is designed to work in conjunction with your existing backup solution to help you achieve the following goals:
• Reduce backup and restore times to below those offered by traditional tape-based systems.
• Simplify your backup infrastructure and make it easier to manage.
• Reduce the amount of data your organization will lose in the event of a server failure or emergency.
• Allow your users to restore their own files in many cases.
How DPM Works
DPM is designed to be installed on dedicated server hardware running the Windows Server 2003 operating system. Your DPM server should have a large amount of available disk storage. Depending on the amount of data you want to protect, you may need to deploy a hardware ATA or SATA RAID disk array; software RAID is not supported. DPM integrates with the Windows Active Directory® directory service to ease management and discovery of protected servers. If your environment requires protecting servers in multiple Active Directory domains, you will need to have at least one DPM server in each domain.
