Deleting Pay-per-Use DB Instances or Read Replicas

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. To delete DB instances or read replicas billed on the yearly/monthly basis, you need to unsubscribe from the order. For details, see Unsubscribing from a Yearly/Monthly Instance.

Before deleting a DB instance, check whether there are any manual backups. If you do not need to retain manual backups, delete them when deleting the DB instance. If you have purchased an EIP, release or unsubscribe from it before deleting the DB instance to save costs.

Billing

  • You will not be billed for the instances that were not successfully created.
  • 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.

Constraints

  • DB instances cannot be deleted when operations are being performed on them. They can be deleted only after the operations are complete.
  • If a backup of a DB instance is being restored, the instance cannot be deleted.
  • A maximum of 50 pay-per-use DB instances can be deleted at a time.
  • 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 rebuild a DB instance that was deleted up to 7 days ago from the recycle bin.
  • You can use a manual backup to restore a DB instance. For details, see Restoring a DB Instance from Backups.
