Android Backup Service is integrated with Android's data backup framework to perform data backup and restore for most devices running Android 2.2 or greater, using Google servers and a backup transport on the device. In some cases, a specific Android-powered device might include a different backup transport for backup services, or might not provide a backup transport at all. Whether or not a device performs backup using Android Backup Service or another service is transparent to applications—the backup APIs used by applications are independent of the backup transport enabled on the device.
