Dropbox is very good mate. <a class="postlink" href="https://www.dropbox.com/pricing" onclick="window.open(this.href);return false;">https://www.dropbox.com/pricing</a>
You can either pay or sign up for a free one and send loads of refferal emails which give you 500mb every time.
Another option as suggested above is use memory stick and put it in a safe or give it to a family member or something?
