Today, the Giveaway of the Day site offers a product to make copies of a drive on your PC.
They say the copy allows you to run your PC on another PC.
I believe it is the same thing as a ghost copy.
I hope so. Better than a backup.
Here's the link to Drive Copy on GAOTD site.
IMPORTANT : All software available for free at GAOTD is free for 24 hours only, as the name of the site implies.
As I write this, there are 20 hours left.
