This page can be used to enable or disable binary logging on the MySQL or MariaDB database server, and to manage existing binary log files. Binary logs record all changes made to databases, and are needed for replication and for point-in-time recovery of backups.

When binary logging is enabled, log files are written under the configured base name and grow as changes are made. To stop them from filling up the disk, a retention period can be set after which old logs are automatically deleted, or old logs can be deleted immediately on the Delete Logs tab. The button at the bottom of the page closes the current log and starts a new one, giving backups and log deletion a clean boundary.

Configuration changes only take effect once the MySQL server is re-started, either with the Save and Restart MySQL button or using the buttons on the module's main page. Deleting and rotating logs happen immediately.
