For years I've not been great at keeping backups, but now my work demands it! For years I've only ever used an external drive always smaller than my internal drive just for important files. I need something to automatically backup the Windows and OSX partitions of my iMac, plus (if possible) create mirrored clones of each partition. The more automated this is the better! My iMacs internal drive is just 1tb so I'm looking at a minimum of 2tb for this new backup solution. Price isn't too much of an issue, capacity is more important than speed too. Such a thing exist?
