Abstract: A system and method for managing data deduplication of a storage system utilizing persistent consistency point images (PCPIs). Once a target PCPI of a data transfer is generated, a backup management module of the storage system alerts a data deduplication module to begin deduplication of the data contained within the target PCPI. Once the deduplication procedure has been completed, the active file system of the storage system has been deduplicated, however, the target PCPI remains un-deduplicated. In response, the backup management module generates and exports a revised target PCPI. The previous target PCPI may then be deleted, thereby transitioning the exported PCPI's image of the state of the file system to a deduplicated state.

Abstract translation: 一种使用持久一致性点图像（PCPI）来管理存储系统的重复数据删除的系统和方法。 一旦产生了数据传输的目标PCPI，则存储系统的备份管理模块警告重复数据消除模块以开始重复数据删除目标PCPI中包含的数据。 重复数据删除过程完成后，存储系统的活动文件系统已被重复数据删除，但目标PCPI保持未重复数据删除。 作为响应，备份管理模块生成并导出修订的目标PCPI。 然后可以删除先前的目标PCPI，从而将导出的PCPI的​​文件系统的状态的图像转换为重复数据删除的状态。
