Google Takeout
Here is a little known Google tool, at least for me, that I found out by some searching. If you use Google Drive for storing your documents, I've always wondered how can you backup your documents that you have written. Well Google thought of that too, because Goggle Takeout allows you to store your +1s, Buzz, Contacts, Drive, Google+ Circles, Google+ Stream, Picasa Web Albums, Profile, Reader, Voice, and YouTube as a downloadabe archive of your data. Problem solved!
