If you use a second DPM server, you can restore data to protected computers directly from the
secondary DPM server. The secondary DPM server can also protect computers until the primary
DPM server is brought back online.
• DPM provides protection of the following items:
• File data from volumes, shares, and folders.
• Application data, such as Microsoft Exchange Server storage groups, Microsoft SQL
Server databases, Windows SharePoint Services farms, and Microsoft Virtual Server and
its virtual machines.
• Files for workstations running Windows XP Professional SP2 and all Windows Vista
editions except Home.
• Files and application data on clustered servers.
• System state for protected file and application servers.

Backup Solutions Combining Disk and Tape
With DPM data protection, you can use disk-based storage, tape-based storage, or both.
Disk-based storage, also called D2D, for "disk-to-disk," is a type of backup in which data from one
computer is stored on the hard disk of another computer. This contrasts with the more traditional
method of backing up data from one computer to a storage media such as tape, also called D2T,
for "disk-to-tape." For extra protection, the two methods can be combined in a disk-to-disk-to-tape
(D2D2T) configuration that provides the rapid recovery benefits of disk-based storage in the short
term and tape-based, archive storage for critical data in the long term. The following illustration
shows the three storage methods.
