This topic uses a PolarDB for PostgreSQL (Compatible with Oracle) cluster as an example to describe how to delete the backup sets of released clusters.
Usage notes
Released clusters in the cluster recycle bin must have at least one backup set. If all backup sets of a cluster are deleted, the cluster cannot be restored.
After you release a cluster, the cluster is asynchronously archived to the cluster recycle bin as level-2 backups at a rate of approximately 150 MB/s. For more information about backups, see Backup and restoration.
Procedure
If you delete all backup sets of a cluster in Cluster Recycle Bin, the cluster cannot be restored. Proceed with caution.
Log on to the PolarDB console.
In the left-side navigation pane, click Cluster Recycle Bin.
In the upper-left corner, select the region in which the cluster is deployed.
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 message that appears, click OK.
