摘要： A system and method to allow mirroring of data into a recovery site in real time so that as data is written disk in a primary data center location, it is concurrently copied to disk at a recovery site, thereby eliminating the use of separate magnetic media for that purpose. Real-time mirroring of data is provided to a separate facility which is connected to a first mainframe data center through appropriate communications circuits. The secondary data center operations are kept current with the primary data center's operations so that in the event of a system failure, operations of the data center can be recovered in an expedited manner.
