Abstract: A technique to name data is disclosed to allow preservation of storage efficiency over a link between a source and a destination in a replication relationship as well as in storage at the destination. The technique allows the source to send named data to the destination once and refer to it by name multiple times in the future, without having to resend the data. The technique also allows the transmission of data extents to be decoupled from the logical containers that refer to the data extents. Additionally, the technique allows a replication system to accommodate different extent sizes between replication source and destination while preserving storage efficiency.

Abstract translation: 公开了一种名称数据的技术，以允许通过复制关系中的源和目的地之间的链路以及在目的地的存储来保持存储效率。 该技术允许源将命名数据发送到目的地一次，并在将来多次引用它，而不必重新发送数据。 该技术还允许数据扩展区的传输与引用数据扩展区的逻辑容器进行解耦。 此外，该技术允许复制系统适应复制源和目的地之间的不同扩展大小，同时保持存储效率。
