Abstract
Disclosed is a system for maintaining consistency of data across storage devices. A cut-off time value is provided to the system. The system then obtains information on data writes to a first storage device, including information on time stamp values associated with the data writes indicating an order of the data writes to the first storage device. At least one group of data writes having time stamp values earlier in time than the cut-off time value is then formed. The system then transfers the data writes in the groups to a second storage device for storage therein.
