 **此页面仅适用于使用文件库和 2012 年原始 REST API 的 Amazon Glacier 服务的现有客户。**

如果您正在寻找归档存储解决方案，建议使用 Amazon S3 中的 Amazon Glacier 存储类别 S3 Glacier Instant Retrieval、S3 Glacier Flexible Retrieval 和 S3 Glacier Deep Archive。要了解有关这些存储选项的更多信息，请参阅 [Amazon Glacier 存储类别](https://www.amazonaws.cn/s3/storage-classes/glacier/)。

Amazon Glacier（最初基于保管库的独立服务）不再接受新客户。Amazon Glacier 是一项独立的服务 APIs ，拥有自己的服务，可将数据存储在文件库中，不同于亚马逊 S3 和 Amazon S3 Glacier 存储类别。在 Amazon Glacier 中，您现有的数据将确保安全，并且可以无限期地访问。无需进行迁移。对于低成本、长期的存档存储， Amazon 建议[使用 Amazon S3 Glacier 存储类别，这些存储类别](https://www.amazonaws.cn/s3/storage-classes/glacier/)基于S3存储桶 APIs、完全 Amazon Web Services 区域 可用性、更低的成本和 Amazon 服务集成，可提供卓越的客户体验。如果您希望加强功能，可以考虑使用我们的 [Amazon 将数据从 Amazon Glacier 文件库传输到 Amazon S3 Glacier 存储类别的解决方案指南](https://www.amazonaws.cn/solutions/guidance/data-transfer-from-amazon-s3-glacier-vaults-to-amazon-s3/)，迁移到 Amazon S3 Glacier 存储类别。

以下代码示例展示了如何：
+ 创建 Amazon Glacier 文件库。
+ 配置文件库，将通知发布到 Amazon SNS 主题。
+ 将档案文件上传到文件库。
+ 启动档案检索任务。
