Control: severity -1 important Hi Jörg,
>> So, did you upgrade your MySQL-Server just before the errors started >> occuring? If yes, from which version to which? > Yes. The update was at 2017-02-01 from version 5.6.35-1 to 5.7.17-1. ok. To make your backups work again, you can remove "NO_ZERO_DATE" from your SQL_MODE setting in your MySQL-server. For details on how to check the current setting and how to change it, please see https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html I'm downgrading the bug to "important" as it does not make the package "unusable for everyone" and thus grave is too severe. I will try to reproduce the error and see if and how it can be fixed or prevented. - Carsten
