Zusammenfassung:A computer implemented method, system, and program product for creating snapshots instructions at a replication site, the method comprising determining the differences between a first snapshot at a first time of a LUN and a second snapshot at a second time of the LUN, determining the differences between the second snapshot and a third snapshot at a third time of the LUN, creating a redacted snapshot of the second snapshot wherein the redacted snapshot contains pointers to the first snapshot for the common data in the first snapshot and the second snapshot; wherein the redacted snapshot contains pointers to the third snapshot for common data in the second snapshot and the third snapshot; and further wherein the redacted snapshot stored data that is not present in the first snapshot and is not present in the third snapshot.
