Advisor check: MySQL Redo log (binary log) not enabled

Description

The binary logs are the change stream of the MySQL instance. It is used for replication and for point-in-time recovery.

It’s recommended to have them on for point-in-time recovery purposes, and so replicas can be promoted to primaries.

This database instance cannot be a replication source, nor could it provide the needed logs for point-in-time recovery. Consider enabling the binary logs.

For more information, see the MySQL documentation.

Resolution

Turn on binary logging by having the log_bin option on the configuration file, and restart the MySQL instance.
