One of the main things I'm concerned with for backing up, besides the usual ordinary files, is the installed apps and all those settings. I.e. I would want to be able to replicate Firefox with especially all the bookmarks. So - what's best for that? I do have an external drive with it's own separate power source, but struggling to understand all these terms everyone throws around. Is ghosting and imaging the same thing? If not, which would be best for regular automatic backup of any new or modified files and apps/settings? Would prefer shareware but will purchase something if it is significantly more reliable and easy to set up and use. Thanks!
