When we first visited the newly released Data Protection Manager, it was a start towards the goal of enterprise backup and archiving, but barely that. It didn't run on 64-bit machines, backed up a few Windows applications, but by no means all — not even Microsoft Exchange Server. And restoration of a dead server from bare metal was a gruesome and tedious process.
That's all changed with Data Protection Manager 2010, has evolved dramatically from the last time we looked. DPM now requires a Windows 2008 (or 2008 R2) 64-bit platform, and includes a handy algorithm concerning both user memory and storage space for the estimated size of DPM storage pools.
