How can I backup an activity without user data?
Currently I use backup_controller class and restore_controller class. Works fine, but I need activity backup/restore without user data
I can not see a way to indicate that I don`t need user data in backup
$bc = new backup_controller(backup::TYPE_1ACTIVITY, $cmid, backup::FORMAT_MOODLE, backup::INTERACTIVE_NO, backup::MODE_IMPORT, $admin_user->id);
