ADB is a CLI tool for Android that lets you perform basic and advanced tasks. You can also use commands to back up your phone’s apps and data. It is always recommended to have a complete backup of your Android device. It becomes even more important if you are into tinkering with your phone and tweaking your device’s software. And you might very well know that your Android device already has a built-in backup system in place. In this tutorial, we’ll explore how to create a backup of Android apps and their data and restore them using ADB commands.

Normal backup and data syncing methods require an active internet connection. The same goes for restoring the backed-up data. With ADB, you can create a backup of apps and their associated data using commands. The best part about this tweak is that you don’t need a rooted device. Let’s now see how to do this.

Please note that the adb backup command works only for those apps that allow backup. If the app’s AndroidManifest.xml has the allowBackup=false declaration, you can’t back up its data using ADB.
