Zusammenfassung:A write operation storing data in a first storage device is duplicated to a first replication file. A set of differences between a first version of the first replication file determined at a first time and a second version of the first replication file determined at a second time is determined, the set of differences comprising a set of results of duplicated write operations occurring between the first time and the second time. At a second file system, storage of the set of differences in a second storage device is caused, creating a duplicate in the second storage device of the data stored in the first storage device.
