PolarDB:Permanently delete a released cluster

Last Updated:Sep 17, 2026

The cluster recycle bin stores released PolarDB clusters. You can restore a cluster from the recycle bin to a new cluster, or delete the backup sets of a released cluster. This topic uses a PolarDB for MySQL cluster as an example to describe how to delete backup sets of a released cluster.

Usage notes

  • A cluster in the cluster recycle bin can be restored only if it has at least one backup set.

  • After a cluster is released, all level-1 backups in the cluster recycle bin are asynchronously archived as level-2 backups at a rate of approximately 150 MB/s. For more information about backups, see backup and recovery.

  • Ensure that your account has a sufficient balance to avoid restoration failures due to overdue payments.

Delete a backup set

  1. Log on to the PolarDB console.
  2. In the upper-left corner, select the region where the cluster is deployed.

  3. In the left-side navigation pane, click Cluster Recycle Bin.

  4. Find the target cluster, and click the Plus icon next to the cluster name to expand the list of backup sets.

  5. Find the backup set to delete, and click Actions > Delete Backup.

    Warning

    If you delete all backup sets of a cluster in Cluster Recycle Bin, the cluster cannot be restored. Proceed with caution.

  6. In the confirmation dialog, click OK.
