摘　　要：云存储系统通过副本管理策略,在廉价设备上提供了对海量数据快速、安全、可靠的存储服务。云存储系统的发展,为云网盘服务奠定了基础。在实际应用中,网盘服务往往会遇到用户上传相同文件或是转存分享文件的场景,原始的云存储系统不会对重复文件进行处理,从而使云存储系统内部产生大量冗余,极大地占用存储资源。提出一种基于Swift云存储组件的冗余去重方法从源头消除冗余的产生,并应用到课件管理子系统中。Cloud storage systems provide a fast, secure and reliable storage service for mass data on commodity hardware through duplicate management strategies. The development of cloud storage system enhanced the foundation of cloud disk service. In practice, the cloud disk service often encounters the scenarios where users upload the same files or share files. The original cloud storage system does not process duplicate files so that a large amount of redundancy storage in the cloud system. Proposes a redundant deduplication method based on Swift cloud storage eliminates the redundant, applies this method to the courseware management subsystem as well.
