backup system to ISO image

[Nhadie <nhadie@gmail.com>]

Hi,

Is there a tool i can use to fully backup a system to an ISO image and 
preserve all files?
So that if ever something happens to any of my server, i can simply 
reinstall from the ISO image, no need for me to do reconfiguration on 
the services running on it.

thank you

regards,
nhadie
