Deleting a Pay-per-Use DB Instance or Read Replica

Scenarios

To release resources, you can delete DB instances or read replicas billed on the pay-per-use basis as required on the Instances page.

Constraints

  • DB instances cannot be deleted when operations are being performed on them. They can be deleted only after the operations are complete.
  • A maximum of 50 pay-per-use DB instances can be deleted at a time.
  • If you delete a pay-per-use DB instance, its automated backups will also be deleted and you will no longer be billed for them. Manual backups, however, will be retained and generate additional costs.
  • If you delete a primary DB instance, its standby DB instance and read replicas (if any) are also deleted automatically. Exercise caution when performing this operation.
  • Deleted DB instances cannot be recovered and resources are released. Exercise caution when performing this operation. If you want to retain data, create a manual backup first before deleting the DB instance.
  • You can use a manual backup to restore a DB instance. For details, see Restoring a DB Instance from a Backup.
