With the introduction of Windows 2008 Server, unfortunately
the back-up possibilities have been limited to the absolute
basic. But...there is DPS 2007 which supports all the stuff
and more...

As I'm running Windows 2008 EE x64 with Exchange 2007 on a
single server, I searched for a solution for being able to
back-up both files and state and Exchange. As up till now I'm
still searching as it turns out that DPS can't be installed
on a DC.

Looking forward how Microsoft solved this in the SBS2008
environment...
