Ghost - How to
It is a good back up should your system go t*ts up. Basically it creates an "image" of your whole disk or a partition (your decision) and places it where you wish - either on another partition or on cd-rom. For example, you can iamge your c drive andd put that image on your d drive. In an emergency, you can boot the system to dos with a boot disk created with Ghost and reinstate the partition or disk that became inoperable with the c drive image you stored on d.
Most handy for images of your c drive as this is the one most likely to fail, but you can use it on any partition or drive. You will of course lose any data from the time you created the image to the time of the failure.
I do this at least once a week (more if time permits) fo peace of mind and it *does* work.
Best!
