I have been looking to backup my computers latley, but that is for another place. In my reaserch I have found a chines backup company that offera a lot of free space. The thing is I don't know how much i trust it. tencent weiyun to be specific.But back on topic if i were to encrypt the data once with 7-zip or AxCrypt, then with VeraCrypt, Both with 20-25 long strong password that I have writen down in a few places. How effective would this be. Or would it just be a waste of my time.
