Google Docs has become the ultimate go-to place when it comes to cloud document storage. The service not only enables you to access your documents and collaborate with other users, but you can also store important files to access anywhere. However, it's always a good idea to back up those documents if, say, your internet goes out, or if Google has another flub like when Gmail managed to accidentally delete a ton of users' emails. Fortunately, there's an easy solution for backing up your files to your hard drive.
