I try to start a DB backup via:
php bin/magento setup:backup --db
But I get this error:
Enabling maintenance mode
DB backup is starting...
Warning: Division by zero in /var/www/magento/vendor/magento/module-backup/Model/Db.php on line 156
Disabling maintenance mode
PHP Fatal error: Uncaught Exception: User Error: Some transactions have not been committed or rolled back in /var/www/magento/vendor/magentframework/DB/Adapter/Pdo/Mysql.php on line 3774 in /var/www/magento/vendor/magento/framework/App/ErrorHandler.php:61

My Magento version: 2.1.1
It's the same via the web interface.
Any help for me here?
Thanks in advance.
Best regards
