    An ISO is a specific image format. Norton Ghost and Acronis True Image use their own proprietary format instead of using ISO for their image format. All three image formats do basically the same thing.

    I think the ISO file is a larger file as it may not crop empty space from the backup. If I am not mistaken ISO is a bit for bit image so it stores even empty space.
