PolarDB:Release a cluster

Usage notes

• You cannot manually release subscription (prepaid) clusters.

  Note

  • For subscription (prepaid) clusters, you can manually Unsubscribe the cluster from the Clusters page. For more information about unsubscription rules, see Unsubscription rules.

  • Before unsubscribing from a subscription (prepaid) cluster, if you want to retain backups, go to Settings and Management > Backup and Restoration > Backup Policy Settings > General and configure the When Cluster Is Deleted option in advance. You can select Retain All Backups, Retain Last Backup, or Delete Immediately. After you unsubscribe from or release the cluster, you can view the retained backup sets in the cluster recycle bin. You can also delete the backups of a released cluster at any time to save costs.

• Clusters that can be manually released:

  • Pay-as-you-go (postpaid) clusters whose Status is Running.

    Note

    If the Status of your pay-as-you-go (postpaid) cluster is Locking, your Alibaba Cloud account has overdue payments. You can top up your account while the cluster is locked. After the payment is completed, the cluster is unlocked and resumes normal operation. You can then manually release the cluster. For more information, see Expiration and overdue payments.

  • Serverless clusters whose Status is Stopped.

• This operation releases the entire cluster, including all nodes in the cluster. To release an individual read-only node, see Add or remove nodes.

Procedure

1. Log in to the PolarDB console，In the navigation pane on the left, click Clusters. Select the Region where the cluster is deployed, and then find the target cluster。

2. In the Actions column on the right side, choose More > Release.

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

   Backup retained	Description
   Automatically back up and retain all backup sets for the cluster long-term	When the cluster is released, all existing backup sets of the current PolarDB cluster are retained.
   Automatically back up and retain the last backup set long-term	When the cluster is released, a full backup is performed, and only this backup set is retained.
   Delete all backup sets for the cluster immediately upon release	After the cluster is released, all backup sets and logs of the current PolarDB cluster are immediately deleted. Warning Selecting this policy causes the current PolarDB cluster to become unrecoverable after deletion.

   Note

   • If you select the Automatically back up and retain all backup sets for the cluster long-term or Automatically back up and retain the last backup set long-term policy, when the PolarDB cluster is released, the system proactively performs a full backup to preserve all data before deletion.

   • After the cluster is released, if you selected the Automatically back up and retain all backup sets for the cluster long-term or Automatically back up and retain the last backup set long-term policy, the following rules apply:

     • For clusters with PSL4/PSL5 storage type, level-1 backups are automatically converted to level-2 backups and retained in the cluster recycle bin. A small fee is incurred.

     • For clusters with ESSD cloud disk storage type, data backups are retained in the cluster recycle bin. A small fee is incurred.

     You can delete the backups of a released cluster at any time to save costs.
