Zusammenfassung: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.
