Abstract: Embodiments of the present invention provide a mechanism for converting an existing mirror relationship between an original dataset at a source storage system and a copy of the original dataset at a destination system to a new mirror without discarding the existing copy of the original dataset and without transferring data to create a new dataset to replace the copy of the original dataset at the destination storage system. Rather, a directory structure (including file attributes) of the source storage system is transferred to the destination storage system and a comparison is made to identify file attributes at the destination system that match the transferred file attributes. If a match is found, a mapping between the matched file attributes is created. Subsequent updates to the to destination storage system can be done using a technique other than the one that was used to create a copy of the source dataset.

Abstract: A system and method for enabling data replication is described. A set of protocol messages can be associated with a set of corresponding set of requests. The associated set of protocol messages can be provided to each of a source storage system and a destination storage system. The source storage system and the destination storage system can be heterogeneous storage systems that implement different types of file systems or file layouts. The source storage system and the destination storage system are enabled to perform a data replication process, in which at least a set of data is to be replicated from the source storage system to the destination storage system, using at least a protocol message from the associated set of protocol messages. The protocol message can correspond to a request for a list of snapshots stored at the source storage system.

Abstract translation: 描述了用于启用数据复制的系统和方法。 一组协议消息可以与一组相应的请求相关联。 可以将关联的一组协议消息提供给源存储系统和目的地存储系统中的每一个。 源存储系统和目标存储系统可以是实现不同类型的文件系统或文件布局的异构存储系统。 源存储系统和目的地存储系统能够执行数据复制过程，其中至少一组数据将从源存储系统复制到目的地存储系统，至少使用来自相关联的协议消息的协议消息 一组协议消息。 协议消息可以对应于存储在源存储系统的快照的列表的请求。
