I was wondering why no tests catched the issue you described. Turns out there's a test, but only for ancient mysql: #1642. |

Should I try and port the test forward before merging @bastelfreak ? |
* When using multiple excluded databases, the list of databases is filtered using `grep -v`. i.e. `grep -v '^\(information_schema|performance_schema\)$` * When using Basic vs Extended Regular Expressions, the characters `(` and `|` lose their special meaning, the backslashed versions have to be used. For the group (`()`) the escaping has been done, however the alternation is unescaped. Leading to: * All the excluded databases will be backed up. * In case a database is not backuppable (which is why it had been excluded), this leads to the cleanup not being run at all, as it depends on the backup having been successful. This MR aims to fix this issue, by revising the regular expression and specifying that behaviour in the respective class spec.
