I am a BIG fan of Data Protection Manager (DPM). DPM is a disk based backup and recovery system under our System Center family of products. I am in the process of acquiring the hardware to implement DPM on my home network and alleviate some of the manual backup duties that I regularly perform.
The Microsoft IT Showcase group has just published a new Technical Whitepaper and a Webcast with great info on how Microsoft uses DPM.

Client data backup and management at Microsoft refers to the methods, services, and processes that are involved in managing both corporate and personal data for client computers. It can also refer to sharing data between employees, teams, or groups. Microsoft IT piloted Microsoft System Center Data Protection Manager 2010 to protect client corporate data and found the program successful, with over 3,000 people now using the service. The service became a part of Microsoft Client Corporate Data Management Service portfolios together with IntelliMirror folder redirection, user state virtualization, and virtual file share storage.
