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.

Note: bmgr restore does not work for encrypted backups.

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.
