bmgr is a shell tool you can use to interact with the Backup Manager on Android
devices version 2.2 (API Level 8) or higher. The tool provides commands to initiate backup and
restore operations so that you don't need to repeatedly wipe data or take similar intrusive steps
in order to test your application's backup functionality. The bmgr tool supports both
Auto Backup and
Key/Value Backup.
You run bmgr commands on a device via
adb shell and then monitor the output of the commands
with logcat. For a list and description of
available commands, run the bmgr tool with no arguments. For information on
triggering backup and restore operations, see
Testing Backup and Restore.
