Claim Text:
1. A method, in a data processing system, for data replication, comprising: dividing a set of data to be replicated into a plurality of slices, wherein each slice of the plurality of slices is to be copied from a primary site to a master secondary site within a plurality of secondary sites, wherein the plurality of secondary sites comprises the master secondary site and at least one subsidiary peer site; copying the plurality of slices from the primary site to the plurality of secondary sites such that the master secondary site stores a first slice of the set of data and the at least one subsidiary peer site stores at least one remaining slice of the set of data; responsive to completion of copying the plurality of slices to the plurality of secondary sites, initiating copying of the at least one remaining slice of the set of data from the at least one subsidiary peer site to the master secondary site and enabling logic for a consolidated read view of the set of data, wherein the logic presents a consolidated read view of the set of data to a client as if the set of data is stored at the master secondary site; and responsive to completion of copying the at least one remaining slice from the at least one subsidiary peer site to the master secondary site, disabling the logic for the consolidated read view of the set of data.
