摘要： A method and apparatus for replicating a data container of a source storage server at the logical level in an unordered stream of individual data units are described. In certain embodiments, the replication operations can be performed without regard to the differences in geometry of physical persistent storage of the source and destination storage servers and without regard to the differences in data container format of the source and destination storage servers. An initial replication operation of the source data container is performed by transferring the data objects within the source data container to a replica data container in the destination storage server as an unordered stream of individual data units while preserving data object identifiers of the source data objects. Afterwards, incremental replication operations can be performed to capture modifications to the source data container over time after the initial replication operation.

摘要翻译： 描述了用于在单个数据单元的无序流中以逻辑级复制源存储服务器的数据容器的方法和装置。 在某些实施例中，可以在不考虑源和目的地存储服务器的物理永久存储器的几何形状差异的情况下执行复制操作，而不考虑源和目标存储服务器的数据容器格式的差异。 源数据容器的初始复制操作是通过将源数据容器内的数据对象作为单个数据单元的无序流传送到目标存储服务器中的副本数据容器，同时保留源数据对象的数据对象标识符来执行的。 之后，可以执行增量复制操作，以在初始复制操作后随时间捕获对源数据容器的修改。

摘要： At least certain embodiments disclose a method and apparatus for replicating a file system at the logical block level in an unordered stream of individual data units. In at least certain embodiments, the replication operations include creating a snapshot of a file system of a source storage system, identifying changes in the file system since a previous replication operation by comparing the snapshot with a previous snapshot created during the earlier replication operation, and asynchronously transferring the identified changes to a destination storage system in an unordered stream of individual data units.
