Scenarios
To release resources, you can delete DB instances or read replicas as required on the Instances page.
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.
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.
- 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 Backups.
