Setting a Local Retention Period for MySQL Binlogs

Scenarios

RDS for MySQL deletes local binlogs after they are backed up to OBS. You can set the local retention period for binlogs as required.

Binlog is enabled for RDS by default and uses the row-based logging.

Binlogs can be retained from 0 to 168 (7x24) hours locally.

The binlogs used for replication between primary DB instances and standby DB instances or read replicas are not deleted, even when the retention period is set to 0.

Procedure

1. Log in to the management console.
2. Click in the upper left corner and select a region and a project.
3. Click Service List. Under Database, click Relational Database Service. The RDS console is displayed.
4. On the Instance Management page, click the target DB instance.
5. In the navigation pane on the left, choose Backups & Restorations. On the Binlog Backups page, click Set Binlog Retention Period.
