Abstract
A primary storage device maintaining recovery data in connection with ordering data writes includes the primary storage device receiving a plurality of data writes, the primary storage device associating data writes begun after a first time and before a second time with a first chunk of data, and the primary storage device associating data writes begun after the second time with a second chunk of data different from the first chunk of data. After completion of all writes associated with the first chunk of data, the primary storage device initiates transfer of writes associated with the first chunk of data to a secondary storage device. The primary storage device maintains a transfer log of data from the first chunk that is successfully transferred to the secondary storage device.
