Google wants to differentiate from other cloud services by offering a lot of ways to export your data. Google Takeout is a feature that’s included in Google+, but it’s also available as a standalone service. You can use it to export your contacts, Google Buzz messages, Picasa Web photos and Profile data with one click.
“Google Takeout lets you take your data out of multiple Google products in one fell swoop. Moreover, you’ll find that all your data is in portable and open formats‚ so it’s easy to import to other services quickly”.
