如何从 AWS Backup 构建 AWS CloudFormation YAML

Question

我正在使用 AWS Backup 服务为我的 DynamoDB 创建备份，但我不喜欢该解决方案，因为它非常手动且不可复制。

现在，我如何构建 AWS Backup（从 CloudFormation Designer 或模板）？

我正在搜索它，但我做不到。

注意：我不想使用任何带有 lambda 的计划事件进行备份。我需要使用 AWS Backup，但我在哪里可以找到用于轻松创建/更新的 CloudFormation 模板。

注意： 将 *********** 替换为您的 AWS AccountId

您需要添加 dynamoDB 标签，例如：

DDBTableWithDailyBackupTag:
        Type: "AWS::DynamoDB::Table"
        Properties:
          TableName: "TestTable"
          AttributeDefinitions:
            -
              AttributeName: "Album"
              AttributeType: "S"
          KeySchema:
            -
              AttributeName: "Album"
              KeyType: "HASH"
          ProvisionedThroughput:
            ReadCapacityUnits: "5"
            WriteCapacityUnits: "5"
          Tags:
            -
              Key: "backup"
              Value: "daily"
