如果你还没有创建备份数据保存目录，可以参考[创建存储桶](https://docs.aws.amazon.com/zh_cn/AmazonS3/latest/user-guide/create-bucket.html)在指定的区域中创建一个 S3 存储桶。如果需要使用文件夹，可以参考[使用文件夹在 Amazon S3 控制台中组织对象](https://docs.aws.amazon.com/zh_cn/AmazonS3/latest/user-guide/create-folder.html)在存储桶中创建一个文件夹。

> AWS 在 2024 年改变了默认行为，新创建的实例默认设置仅支持 IMDSv2，详情请参考[将 IMDSv2 设为账户中所有新实例启动的默认设置](https://aws.amazon.com/about-aws/whats-new/2024/03/set-imdsv2-default-new-instance-launches/)。因此从 v8.4.0 开始，BR 支持在仅开启 IMDSv2 的 AWS EC2 实例上获取 IAM role 权限。在使用更早版本的 BR 时，需要设置实例为同时支持 IMDSV1 和 IMDSV2。
