Windows 2003 Server “disc image / recovery discs” creation

Hi All
I have a dell poweredge 850 server and Powervault NAS running. I wish to make a recovery image of both these. I believe the NAS uses raid 5 and have heard you cannot image or ghost such a setup.

I basically want to create something that will restore my server and nas to exactly what it was before “whatever/fire/sinking” etc.. happened. just like most new pc’s do with the rescure and recover discs
insert cd /external hhd and recover everything.

Is there something out there that will allow me to do this. I dont care how many external HHD I need to buy. keeping the system running is worth more…

Best Regards
