Server support
Server support is more a limitation of hardware driver availiblity. Does it boot up and allow access to the usual raid controller in use. As for 2003 my experience is that most tools that work for xp and vista, work fine restoring 2003/2008, if they can boot. Many of the live cloning tools require you to reinstall the OS then restore the system. (but it works)
In actuality, I find backing up the data only, and having notes etc to reinstall OS/services is actually faster than restoring a system, plus being fresh fixes ghosts in the system.
Also other than clonezilla, all of these are backup and restore programs are not designed to distribute/clone an image for system builders.
I am a fan of FOG (Free and Open Ghost) it requires a dedicated server, time, heartache, and trial and error; but it works. Just remember that none of the imaging/backup solutions that are avalible today are 100% and all of them have troubles with drivers on newer systems. (Bane of our existance)
