You should always make sure that the personal content on your device, such as photos, videos, SMS text messages, contacts and applications, are synced or a backup is completed on a regular basis.

The recommended solution is to use the Google Cloud™ services, including Google account sync, Google Drive™, and Google Photos™. An alternative method is to use a PC or SD card.
