Deleting a DB Instance


You can manually delete the following DB instances that are not in use to release resources:

  • Primary DB instances
  • Read replicas (RDS for Microsoft SQL Server does not support read replicas.)


  • DB instances in the creating status cannot be deleted.
  • If you delete a DB instance, its automated backups are also deleted and you are no longer charged for them. Manual backups are still retained and will incur additional costs.
  • If you delete a primary DB instance, its read replicas are also deleted automatically. Exercise caution when performing this operation.
  • Deleted DB instances cannot be recovered. Exercise caution when performing this operation.


  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 to go to the RDS console.
  4. On the Instance Management page, locate the target DB instance or read replica, and choose More > Delete in the Operation column.
  5. In the displayed Delete DB Instance dialog box, click Yes. Refresh the Instance Management page later to verify that the DB instance or read replica has been deleted.
