I use Carbonite to back up user files on 20 computers. These are windows 10 computers. I was thinking of making a recovery drive or a system image back up for each of these computers. If the computer crashed and I had to use either of these options, which would be the quickest way to get back up and running considering I use Carbonite for user back up? recovery drive her system image back up? Also, can I create a system image back up and a recovery drive on a Nas?
