Release a cluster

Considerations

• You cannot manually release subscription clusters. Subscription clusters are automatically released when they expire.
• You can manually release the cluster whose Status is only 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 read-only nodes.

Procedure

1. Log on to the PolarDB console.
2. In the upper-left corner of the console, select the region where the cluster resides.
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	Description
   Retain All Backups Permanently	Retains all the backups for a cluster when you delete the cluster.
   Retain Last Automatic Backup Permanently	Retains the last backup for a cluster when you delete the cluster.
   Delete All Backups Immediately	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 Retain All Backups Permanently or Retain Last Automatic Backup Permanently policy, the system runs an automatic backup task to retain all the data about a cluster when you delete the PolarDB cluster.
   • After you delete a cluster, level-1 backups are automatically transferred to level-2 backups. You can go to the Cluster Recycle page to view retained backups. For more information, see Cluster recycle bin.
