The number of days for which ElastiCache will retain automatic cache cluster snapshots before deleting them. For example, if you set
            SnapshotRetentionLimit to 5, then a snapshot that was taken today will be retained for 5 days before being deleted. If you do not
            specify this parameter, then SnapshotRetentionLimit will be set to 0 (i.e., automatic backups will be disabled for this cache
            cluster).
