+###### Note
+
+No-backup tables aren't supported for RA3 provisioned clusters and Amazon Redshift Serverless workgroups. A table marked as no-backup in an RA3 cluster or serverless workgroup is treated as a permanent table that will always be backed up while taking a snapshot, and always restored when restoring from a snapshot. To avoid snapshot costs for no-backup tables, truncate them before taking a snapshot.
