I think that Google Cloud is good, but yeah, I wouldn't back up everything to it. I am going to tell you one thing that I like, and don't like, is OneDrive. I don't like the way OneDrive takes over your computer, to the point where when you open another PC that you have, it automatically uploads all of your stuff from your previous PC on to the other one. Also, it messes up your system. You find that you can't even open files unless OneDrive is running. OneDrive has some issues.
