Just a word of caution there Ian. I am a great backup nerd. But it is wise to make sure you do not erase the original, or at worse, a very (100%) reliable image. It is so easy to make a subsequent image which will include any faults/problems encountered. Space these days is not a problem for most. I normally have two or three dated images on my computer, but always have 1. The original, barebones, installation image and 2. The image of the installation and all my regular, configured, software.
I do use Acronis, but that is off topic. I find, if anything is in the smallest way suspect, it is quicker to replace the image than start fault finding (Takes about 15 to 20 minutes to restore 21 gbs.). Of course, there are many reasons why a user would want to find the fault first.
