A primary storage device (24) orders a plurality of data writes by associating data writes begun after a first time and before a second time with a first chunk of data (52), associating data writes begun after the second time with a second chunk of data (54) different from the first chunk of data, and, after completion of all writes associated with the first chunk of data, initiating transfer of writes associated with the first chunk of data to a secondary storage device (26).
