Brian Moran, SQL Server MVP & SQL Server Magazine writer had this to say:

“I love the fact DPM 2007 inherently understands all of the core server technologies in the Microsoft arsenal. It's nice that an administrator can use a single tool to protect data. It's even lovelier that DPM 2007 supports the ability to treat data from different sources as part as the same "protection group." For example, if my accounting team uses SharePoint, OS files, and SQL Server databases as part of their core functionality, and I want to restore my "accounting team" to a single consistent point in time, DPM 2007 can handle that for me. That's sweet.”

“Historically, most enterprise and midmarket customers have had to rely on several third-party offerings to manage their SQL Server backup infrastructure. Historically, backup hasn't really been seen as the cool and sexy part of database management, not that the outside world considers database management to be hot and sexy to begin with. I think the current iteration of DPM 2007 is a large upgrade in functionality from prior Microsoft offerings.

Realistically, many SQL Server customers will be able to standardize on DPM Realistically, many SQL Server customers will be able to standardize on DPM 2007 as their primary, and perhaps only, tool for managing backup and 2007 as their primary, and perhaps only, tool for managing backup and protection of SQL Server dataprotection of SQL Server data.”
