Google Sync

Google Sync was a file synchronization service from Google that provided over-the-air synchronization of Gmail, Google Contacts, and Google Calendar with PC and mobile device Mail, Calendar and Address Book applications. It used Microsoft® Exchange ActiveSync® to let service users synchronize their Google Apps mail, contacts, and calendars to their mobile devices, wherein the users can also set up or customize the alerts for incoming messages and upcoming meetings. Google Sync worked with PC, Mac, Linux, Android, BlackBerry, Symbian S60, iPhone, iPad, Windows Mobile, and other devices. Google Sync was announced in February 2009 and discontinued for non-business users in December 2012.

Features
Google Sync was a bidirectional service. Changes made on one device would be backed up to the user's Google Account. All other Google data on devices sharing that same Google account would be automatically synchronized as well. In case the user's Mobile Device is lost, the data is still securely stored.
