How do I recover a crashed Server?

Hi All,

I have a quick question about recovering a crashed server ( its not crashed yet).  I want to be able to restore all Server settings by one or two clicks, same like HDD clone or ghosting method that we use to re-image or restore crashed OS.

Can we do that by Netbackup program or do I need to get another software to save me time after disater happens?  

Thanks,

Ed
