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


  • Released clusters in Cluster Recycle must have at least one backup set. If all the backup sets of a cluster have been deleted, you cannot restore the released cluster.
  • After a cluster is released, all level-1 backups in Cluster Recycle are asynchronously archived to level-2 backups at a rate of approximately 150 MB/s. For more information about backups, see Data backups .

  1. Log on to the PolarDB console.
  2. In the upper-left corner of the console, select the region where the cluster that you want to manage is deployed.
  3. In the left-side navigation pane, click Cluster Recycle.
  4. Find the cluster that you want to manage, and click the Plus icon icon next to the cluster to show a list of backup sets.
