Abstract:
A data-allocation data-replication system includes a controller adapted to respond to back-up requests from host systems by first allocating an accumulated data set containing multiple source data sets. An index data set is then allocated incorporating index keys and other information helpful to restore the source data sets, such as locations of individual source data sets within the accumulated data set.
