Is there a personal cloud solution that keep versions for documents? [closed]

Unbeknownst to many people, but knowst to us (Spaceballs movie reference), Dropbox does keep file versions.

"Dropbox is like a time machine. It keeps snapshots of every change in your Dropbox folder over the last 30 days (or longer with the Packrat feature). So even if you saved a bad change, or if the file has been damaged or deleted, you can restore the file to an older version with only a few clicks."

The free and open-source OwnCloud allows this. You can set it up on your personal server, or use one of the providers. Also, if it's on your own server, it's unlimited storage and guaranteed NSA-free (and Condoleezza Rice–free).

Microsoft OneDrive is a great free product with up to 15GB Free storage, that keeps your previous versions.

It's super handy if you already have a Microsoft email account, and you can install a client locally that will sync your changes online. Easily accessible from anywhere!

Good luck :)
