I'm glad the Exchange team is picking up the ball that the Windows Backup team dropped. The Vista and Server 2008 backup applications are horrible. Honestly, NTBackup was not that feature rich, so I don't see how the Windows team could come up with such a lacking solution. I don't ask for much, I really don't. And, yes, I do appreciate the "quick" options to do a full (including system state) backup. However, not being able to exclude a folder is absolutely ridiculous (that's been available in every backup app since the beginning of time itself). Despite that, I learned to live with it -- I bought bigger hard disks. But not being able to backup exchange?! That is incredibly short-sighted and I wasted a LOT of man-hours trying to figure out a cost effective work-around (currently backing up from a Server 2003's NTBackup after turning streaming network backup back on in the registry).
Thanks, Exchange Team, for developing this plug-in that was neglected by the Windows Team.
