Just out of curiosity is their no 'Clone' possible of a WinTel machine? I use Carbon Copy Cliner daily to (incrementally) clone my iMac's HD. If I need to I can boot from the clone.
I also use Apple's Time Machine to back up hourly and I also copy my Documents, Music and Pictures folders nightly to a third external drive.
Ya, whatever, belts and braces but I'm fairly confident that I won't ever lose my files.
