摘要：A mechanism is provided in a data processing system for data replication. Themechanism divides a set of data to be replicated into a plurality of slices. Each slice of the
plurality of slices is to be copied from a primary site to a master secondary site within aplurality of secondary sites. The plurality of secondary sites comprises the mastersecondary site and at least one subsidiary peer site. The mechanism copies the pluralityof slices from the primary site to the plurality of secondary sites such that the mastersecondary site stores a first slice of the set of data and each of the at least one subsidiarypeer site stores a corresponding slice of the set of data. Responsive to completion ofcopying the plurality of slices to the plurality of secondary sites, for each of the at leastone subsidiary peer site, the mechanism initiates copying of the corresponding slice ofthe set of data to the master secondary site.
