Google Voice is the newest addition to Google Takeout, the search giant's archival tool that lets users download their data from many Google services, including Buzz, Picasa, and Google+.

"This means that all of the data associated with your Google Voice account, from your call history to voicemail messages, greetings and call recordings, is now available for download," writes Google software engineer Anthony Jawad on the Google Voice Blog.

Not everyone wants (or needs) to export voice and text messages, of course, which seem a lot less indispensable than family photos in Picasa. Then again, Takeout may come in handy for small businesses seeking a local archive of Google voice and text messages.

To use the service, you must first choose which Google services you want to archive (Voice and Buzz, for example). Takeout calculates the estimated number of files and archive size, and then creates a downloadable backup file.

Takeout exports voicemail messages and greetings as MP3s, text messages as microformatted HTML, and forwarding phone numbers as a vCard, Google says.
