The cluster recycle bin stores released PolarDB clusters. You can restore a cluster from the recycle bin to a new cluster, or delete the backup sets of a released cluster. This topic uses a PolarDB for MySQL cluster as an example to describe how to delete backup sets of a released cluster.
Usage notes
-
Each cluster in the cluster recycle bin must retain at least one backup set. If all backup sets of a cluster are deleted, the cluster cannot be restored.
-
After you release a cluster, if you choose to retain backups, the relevant data backups are saved in the cluster recycle bin. For more information, see Cluster recycle bin.
-
Make sure that your account balance is sufficient to avoid restoration failures due to overdue payments.
