It sounds like you want a high availability system.  This can get *REAL* 
complicated, depending on exactly how you define "high availability".

I suggest you start at the linux-HA site:
http://www.linux-ha.org/

...read the linux-HA HOWTO:
http://sunsite.unc.edu/pub/Linux/ALPHA/linux-ha/High-Availability-HOWTO.html

...and put some serious thought into exactly *HOW* available you really 
your system to be.  Is a nightly rsync good enough?  Do you really need 
fully transparent failover, and if so, do you have the budget (not only 
in $ but in install/configuration/maintainence man-hours & knowledge) to 
implement it?
