ABSTRACT:
A data network with a remote data facility for providing redundant data storage and for enabling concurrent access to the data for multiple purposes. A local data processing system with a data facility stores a data base and processes transactions or other priority applications. A second system, physically separated from the first system includes the remote data facility that normally mirrors the data in the first system. In an independent access operating mode, the second system is enabled to operate on the data within its data facility concurrently with, but independently of, the operation of the first system. On completion of the independent operation, the second system reconnects with and synchronizes with the first system thereby to reestablish the mirroring operation of the second system.
