This topic describes how to delete the backup sets of a released cluster, using a PolarDB for PostgreSQL or cluster as an example.
Precautions
-
Each cluster in the Cluster Recycle Bin must have at least one backup set. If you delete all backup sets for a cluster, the cluster cannot be recovered.
-
After a cluster is released, the system asynchronously archives it as a level-2 backup in the Cluster Recycle Bin at a rate of about 150 MB/s. For more information about backups, see backup and recovery.
Procedure
If you delete all backup sets for a cluster from the Cluster Recycle Bin, the cluster cannot be recovered. Proceed with caution.
Log on to the PolarDB console.
-
In the left-side navigation pane, click Cluster Recycle Bin.
-
Select the region where the cluster is located, find the target cluster, and click the
icon to the left of the cluster name to expand the backup set list. -
In the Actions column of the backup set that you want to delete, click Delete Backup.
-
In the dialog box that appears, click OK.
