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.

Considerations

  • 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 .

Delete a backup

  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.
  5. Find the backup set that you want to delete, and click Delete in the Actions column.

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