Microsoft DPM Review

Recovery.

Yes: failure of primary; agent resource use.

I'm afraid I fail to see how the CEO of a 500+ employee company can be a "real user" in any relevant sense. The real hands-on experience with DPM is that it's difficult to set up unless you get it right first time, the agent processes gobble CPU and i/o, and if you're unfortunate enough for your DPM primary to go awol, you're faced with building a complete DPM network again because the secondary/ies will refuse full backups if the primary isn't there.
