PolarDB:Release a cluster

Prerequisites

Before you begin, ensure that you have:

• A pay-as-you-go PolarDB cluster in the Running state

Before you release a cluster

• Releasing a cluster deletes all nodes in that cluster. To remove individual nodes without releasing the entire cluster, see Add or remove nodes.

• After a cluster is released, level-1 backups automatically become level-2 backups. View retained backups on the Cluster Recycle Bin page. To restore a released cluster, see Restore a released cluster.

Release a pay-as-you-go cluster

1. Log on to the PolarDB console.

2. In the upper-left corner, select the region where the cluster is deployed.

3. On the Clusters page, find the target cluster and choose More > Release in the Actions column.

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

   Warning

   If you delete all backup sets of the cluster, the cluster cannot be restored. Proceed with caution.
