Microsoft's Data Protection Manager 1.0 (DPM) is the company's first attempt at enterprisewide data protection. In tests, the product performs respectably in management, archiving, and data backup and restore. However, DPM is limited to Microsoft-only machines, and does not yet offer support for the company's full range of applications. DPM cannot run on 64-bit hardware and cannot run using x86 emulation mode. This will change when Microsoft releases its expected service pack either as a server or a protected device. DPM does not offer support for many Windows client types, including Windows CE devices, older versions of Windows, Windows Media Center, and Windows-based mobile phones. It is surprising that Windows platform compatibility is so immature for a product that users would hope to utilize to address critical issues of availability and archiving. Another downside is that DPM cannot fully protect Microsoft Exchange. Other Microsoft and third-party methods are available for increasing Exchange availability, but DPM is unable to perform such simple tasks as taking a snapshot of Exchange without the application shutting down. The product's lack of compatibility even with Microsoft's own applications, and being restricted to only two 32-bit platforms, namely Microsoft Storage Server and Windows 2003 Server editions, makes for serious limitations. However, for highly homogenous Microsoft late-model 32-bit platforms, DPM offers robust back-up and restore features for Web and file servers and client Windows PCs.
