mate, wondered if you have encountered "timeshift"?
It can be seen on a Youtube video, here. I couldn't find one (yet) for systemback, which is not to say it is not a good solution. Thought I'd give timeshift a whirl, as it looks wizard-friendly. Also it is supposed to be good for both Ubuntu and Linux Mint, maybe more.
It is mentioned as being from teejee2008, whom you will know as being the author/s of your Aptik backup solution, which I tried yesterday and worked a treat, thankyou!
One reference to teejee2008 said, in part : "You can update your system with unsupported packages from this untrusted PPA by adding ppa:teejee2008/ppa to your system's Software Sources."
BUT, it is on Launchpad, further, it features in Trusty Tahr's Ubuntu Software Centre and Synaptic Manager, so it must be trusted at least by Ubuntu? What do you think?
