The tool provides commands to initiate backup and\nrestore operations so that you don't need to repeatedly wipe data or take similar intrusive steps\nin order to test your application's backup functionality. The `bmgr` tool supports both\n[Auto Backup](/guide/topics/data/autobackup) and\n[Key/Value Backup](/guide/topics/data/keyvaluebackup).\n\nNote: `bmgr restore` does not work for\n[encrypted backups](/guide/topics/data/autobackup#define-device-conditions).\n\nYou run `bmgr` commands on a device via\n[adb shell](/studio/command-line/adb) and then monitor the output of the commands\nwith [logcat](/studio/command-line/logcat). For a list and description of\navailable commands, run the `bmgr` tool with no arguments. For information on\ntriggering backup and restore operations, see\n[Testing Backup and Restore](/guide/topics/data/testingbackup).\n\nFor information about adding support for backup in your application, read [Data Backup](/guide/topics/data/backup)"]]
