-- * 'prrPreferredBackupWindow' - The daily time range during which automated backups are created if automated backups are enabled, using the @BackupRetentionPeriod@ parameter.  Default: A 30-minute window selected at random from an 8-hour block of time per AWS Region. To see the time blocks available, see <http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/AdjustingTheMaintenanceWindow.html Adjusting the Preferred Maintenance Window> in the /Amazon RDS User Guide./  Constraints:     * Must be in the format @hh24:mi-hh24:mi@ .     * Times should be in Universal Coordinated Time (UTC).     * Must not conflict with the preferred maintenance window.     * Must be at least 30 minutes.
--
-- * 'prrBackupRetentionPeriod' - The number of days to retain automated backups. Setting this parameter to a positive number enables backups. Setting this parameter to 0 disables automated backups. Default: 1 Constraints:     * Must be a value from 0 to 8
--
-- * 'prrDBInstanceIdentifier' - The DB instance identifier. This value is stored as a lowercase string. Constraints:     * Must match the identifier of an existing Read Replica DB instance. Example: @mydbinstance@
