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 ApsaraDB PolarDB MySQL-compatible edition 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 .
Delete a backup
- Log on to the PolarDB console.
- In the upper-left corner of the console, select the region where the cluster is deployed.
- In the left-side navigation pane, click Cluster Recycle.
- Find the cluster that you want to manage, and click the icon next to the cluster to show a list of backup sets.
- Find the backup set that you want to delete, and click Delete in the Actions column.
- In the pop-up dialog box, click OK. Warning If you delete all the backup sets of a cluster in the Cluster Recycle, the cluster cannot be restored. Proceed with caution.
