Abstract

Ordering data writes includes at least some of a group of primary storage (51) devices receiving a first plurality of data writes, causing a cycle switch for the group of primary storage devices where the first plurality of data writes are associated with a particular cycle on each primary storage device in the group, and at least some of the group of primary storage devices receiving a second plurality of writes after initiating the cycle switch where all of the second plurality of writes are associated with a cycle different from the particular cycle on each primary storage device (51). Writes to the group begun after initiating the cycle switch may not complete until after the cycle switch has completed. Recovering data provided in chunks (52) to a plurality of secondary storage devices (62) includes, for each of the secondary storage devices, discarding data corresponding chunks for which all data thereof has not been received, and, for each of the secondary storage devices, restoring a chunk (56) of data where all of the chunks transmission cycle of primary storage devices that provide data to the plurality of secondary storage devices.
