Cloudformation BackupRetentionPeriod 对 RDS Aurora 集群没有任何影响

Question

我在我的 cloudformation 模板中设置了 BackupRetentionPeriod: 15。

DatabaseCluster:
DeletionPolicy: Retain
DependsOn:
- MyDBEnhancedMonitoringRole
Properties:
  BackupRetentionPeriod: 15
  DBClusterIdentifier: AppName-Test-database000001
  DBClusterParameterGroupName: default.aurora-postgresql10
  DatabaseName: !Ref 'DBName'
  Engine: aurora-postgresql
  EngineVersion: '10.11'

但是，它对实际实例没有任何影响。

PS:
我尝试在 DBInstance 级别设置 BackupRetentionPeriod 但它不允许我这样做，因为它是一个集群。

实际上它在工作！

aws-cli describe-db-clusters 显示修改生效

$ aws rds describe-db-clusters  --db-cluster-identifier appname-test-database000001
{
"DBClusters": [
    {
        "AllocatedStorage": 1,
        "AvailabilityZones": [
            "eu-central-1a",
            "eu-central-1b",
            "eu-central-1c"
        ],
        "BackupRetentionPeriod": 15,
        "DatabaseName": "database000001",
        "DBClusterIdentifier": "appname-test-database000001",
        "DBClusterParameterGroup": "default.aurora-postgresql10",
       .....
       }

混淆是因为 UI，它显示 PerformanceInsights 而不是 Backup
