After you release a PolarDB for PostgreSQL (Compatible with Oracle) cluster, the cluster is asynchronously archived to the Cluster Recycle Bin as level-2 backups at approximately 150 MB/s. You can delete individual backup sets from the recycle bin when they are no longer needed.
Prerequisites
A released PolarDB for PostgreSQL (Compatible with Oracle) cluster in the Cluster Recycle Bin.
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.
