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

My Magento version: 2.1.1

It's the same via the web interface.

Any help for me here?

Thanks in advance.

Best regards
