Restore to spare drive?

Does anyone know of how to restore the MBR/SYSVOL/_C_VOL vhdz to a spare drive connected to server. I would like the ability to restore to a drive on esata and then pop it into the computer to minimize downtime and quickly replace small drive with large drive. The server would be running linux and the images would be of windows 7 clients.

Maybe this helps:

It wont run on a 64bit system
Starting restoration…
/root/bin/ 18: /root/bin/ ./urbackup_client: not found
Wizard stoped with error code: 127
cat: restore_wizard.txt: No such file or directory

Is there another version or is it only for 32bit or did I do something wrong?
