System for multiple data transfer operations

摘要

Disclosed is a system for transferring data involving a data movement, such as the duplication of address information, that includes two data movement components. A first data transfer from at least one source storage location to at least one target storage location is processed. A data structure indicates the source storage locations from which data was transferred during processing of the first data transfer. A second data transfer from a plurality of source storage locations to a plurality of target storage locations is processed. The data structure is then processed to determine the source storage locations included in the second data transfer that were not involved in the first data transfer. Data is then transferred from the source storage locations that were not involved in the first data transfer to the target storage locations that did not receive data during the processing of the first data transfer.
