Supposedly:

http://relax-and-recover.org/

supports a GPL Linux bare metal disaster recovery solution that is 
purported to be easy to set up and requires no maintenance.

Does anyone have experience with this application?  Does it perform as 
is claimed?  Is it truly bare metal:  if one provides compatible 
hardware after a "bare metal" failure, will this system "automagically" 
provide a fully operational clone?  (Compatible hardware means a system 
for which the drivers exist in and are automatically loaded and 
configured by the environment being "bare metal recovered", even if the 
new "bare metal" is a different hardware configuration than the failed 
unit.  Thus, an IA-32 environment should boot on many generic X86-64 
platforms, but a pure X86-64 implementation cannot run on a true IA-32 
machine -- the IA-32 machine is not compatible hardware in the latter 
situation.)

Thanks for any information.
