A typical lifecycle is as follows:

• User installs your app for the first time
• App starts, sees it has no existing data, makes a request to restore backup
• No data is found, your app creates stub data
• Users uses your app, generates data: Your app requests a backup
• Further use, further backups...
• User downloads your app onto a new device
• App starts, sees it has no existing data, makes a request to restore backup
• Data is found, restored and returned to your app
• User continues where they left off

var appData = {
  user: {
    id: 1678,
    name: 'Fred',

    preferences: {
      mute: true,
      locale: 'en_GB'
    }
  }
}

plugins.backup.save(appData);

function handleRestore (data) {
  if (data) {
    appData = data;
  }
  else {
    // initialize first-use data
  }
}

plugins.backup.restore(handleRestore);
