Data backup retention policies
If the Backup Retention Policy After Release parameter is configured for the RDS instance, the backup files of the RDS instance are retained even if you release or unsubscribe from the RDS instance. You can download the backup files to your computer. If you set the parameter to Latest or All, fees are generated the backup storage. For more information about how to delete backup files, see Use the backup for deleted instances feature.
Cross-region backup retention policies
If the cross-region backup feature is enabled for the RDS instance and the instance is within the retention period, the backup files that are generated by using the cross-region backup feature are retained.
Immediate data deletion

Before you release or unsubscribe from an RDS instance, we recommend that you back up the RDS instance and download the backup files.
You can release or unsubscribe from the primary or read-only RDS instance based on the following rules:
If you want to release or unsubscribe from the last read-only RDS instance of a primary RDS instance, you must disable the read/write splitting feature for the primary RDS instance.

FAQ
If I release or unsubscribe from a read-only RDS instance, are my workloads interrupted?
Yes, if you release or unsubscribe from a read-only RDS instance, your workloads on the read-only RDS instance are interrupted.
If you enable the database proxy feature for your RDS instance, we recommend that you set the read weight of a read-only RDS instance to 0 before you release or unsubscribe from the read-only RDS instance. The cached connection to the read-only RDS instance remains valid. If you want to forward read requests to other read-only RDS instances, you must establish new connections.
If you disable the database proxy feature for your RDS instance, you must modify the application code to replace the connection settings for the read-only RDS instance that you want to release or unsubscribe from with the connection settings of another read-only RDS instance or the primary RDS instance.
After I release or unsubscribe from my RDS instance, how do I retrieve the data of the RDS instance?
If your RDS instance is configured to retain backup files after you release or unsubscribe from your RDS instance, you can go to the Backup for Deleted Instances tab of the Backups page in the ApsaraDB RDS console to restore the data of your RDS instance.
I cannot find Release Instance in the ApsaraDB RDS console. Why?
