What is an AB file?

Backup file created by adb (Android Debug Bridge), a command-line tool included with the Android SDK; can include both apps, system, and user data from an Android 4.0 or later device; used for saving and restoring device snapshots.

More Information

Often AB backups do not include the .APK apps themselves, but only the device's app and system supporting data. For example, you can backup the data of a connected Android device without the APK files by typing the following command:

adb backup -all

This creates the file backup.ab in the current directory. To include the APK files as well, use the following command:

adb backup -apk -all

To restore an AB backup file to the device, type the following command:

adb restore backup.ab

The adb program also includes options to include or exclude other types of data and to specify the backup filename. Consult the ADB documentation for further information.
