What Is Background Syncing in Google Chrome

Background syncing in Google Chrome is a feature that allows the browser to sync your browsing data with Google’s servers even when the browser is closed or not actively in use. This ensures that your data is always up to date across all your devices.

Background syncing in Google Chrome works as follows:

  • When you make changes to your browsing data, such as adding a new bookmark or visiting a new website, Chrome saves those changes locally on your device.
  • Chrome then schedules a background sync, which uploads those changes to Google’s servers at a later time.
  • The background sync process is optimized to minimize battery and data usage if using the Chrome mobile app. It uses an adaptive algorithm to determine when to sync based on factors such as battery level, network conditions, and device usage patterns.
  • Once the changes have been uploaded to Google’s servers, they are synced to all other devices signed in with the same Google account.

Background syncing is especially useful for users who frequently switch between devices or who need to access their browsing data from multiple locations. It ensures that your data is always up to date, even when you’re not actively using the browser.

To enable background syncing in Chrome, first you need to sign in to your Google account and turn on syncing. You can also choose which types of data to sync and which devices to sync with from the Chrome settings. You can also password-protect your syncing, here is how.
