I forget if this has been mentioned, but I put almost all my folders inside my Dropbox folder. Then I have, at Dropbox, paid for 100G storage and--most important--signed up for "pack rat": this keeps and makes available to you all your old saves of files. I don't know how they do it, spacewise. Attached is a screenshot--note this file has over 700 older versions!Attachment: DB versions.jpg
