Question : Syncronize Physical Machine with Virtual Machine

I'd like to syncronize my windows 7 physical machine with a virtual copy made with MS Virtual PC. (VMware also OK.)  What I want to do is have a backup system available for high availability.  I know it's relatively simple to deal with the sync'ing of data files, but I also want to be able to install programs on the physical machine and have the changes mirrored on the virtual machine.  

I guess this comes down to what changes are made to the files from the physical machine to make them virtual, and if it's possible to sync the machines, including the registry, without breaking the virtual setup.

Answer : Syncronize Physical Machine with Virtual Machine

You could install vmware converter on the physical machine and from time to time run a Physical to virtual conversion.  This would give you a virtual copy when you needed it.  

Another solution is to use Norton Ghost and image the physical machine to a USB for instance.  At any time the image can be converted to a virtual machine, either vmware or MS Virtual PC (VMware is easier though).  You could setup a schedule and do this on a regular basis, whatever changes on the physical would get replicated to the image and thus the virtual machine
