SpiderOak lets me easily backup, sync, share, remotely access and store all my data. I can add as many different computers and drives to a single account so all my data can live in a central location. The application has been working for me very nicely. You can sign up if you use the download link below and we will both receive an additional free 1 GB of storage. And you can also feel free to refer as many friends as you like. https://spideroak.com/download/referral/4b45441744da1e2594e73340d41e2553
