PolarDB：Release a cluster

Precautions

• You cannot manually release subscription clusters.

• You can manually release clusters whose Status is Running.

• You can use this feature to release clusters. If this feature is used, all the nodes of the clusters are released. For more information about how to release a single read-only node, see Add or remove a read-only node.

Procedure

1. Log on to the PolarDB console.
2. In the upper-left corner of the console, select the region in which the cluster that you want to manage is deployed.

3. On the Clusters page, find the cluster that you want to release and choose More > Release in the Actions column.

4. In the Release Cluster dialog box, select a backup retention policy and click OK.

   Retain Backups value	Description
   Permanently Retain All Backups	Retains all the backups for a cluster when you delete the cluster.
   Permanently Retain Last Automatic Backup	Retains the last backup for a cluster when you delete the cluster.
   Immediately Delete All Backups	Deletes all the backups for a cluster when you delete the cluster. Warning If you select this policy, the deleted clusters cannot be restored.

   Note

   • If you select the Permanently Retain All Backups or Permanently Retain Last Automatic Backup policy, the system runs an automatic backup task to retain all the data about a cluster when you delete the PolarDB for MySQL cluster.

   • After you delete a cluster, level-1 backups automatically become level-2 backups. You can go to the Cluster Recycle page to view all backups. For more information, see Restore a released cluster.
