To use Simple ADB Backup, you’ll need USB Debugging Mode enabled on your Android device (Go to Settings > Developer, enable developer options, then enable USB debugging) and the utility installed on your desktop. That’s about it: just plug in your phone, launch the app on your Windows or Linux system, and choose a backup option. You have the option to back up your entire device, just apps, all data with or without system apps, or even a single app if you choose.
