Occasionally I am not an advanced user, right. But I really love this OS and I just want to use it as a clean "Host OS", as I will install a Win10 VM for work and gaming apps.
When I'm not working or gaming, I want to advance my linux "skills" and I really like to play around with the settings because everything is customizable.
Sooner or later I will definitely broke something and I want to be able to restore the following with just a few mouse clicks:
All customized settings like panels, docks, widgets, gestures, hotkeys, networks, vpns....
All apps and logins like dropbox, keepass, firefox...
All files from /home
So I want to use this as my main OS for daily use but I also want to play around with new things without the fear of loosing all my settings and data.
I would really appreciate a short guide to what's the best tool to get this done and how to do it.
