Patent
Method and system for automated termination and resumption in a time zero backup copy process
Lawrence Elwood Eastridge,Robert Frederic Kern,William Frank Micka,Claus William Mikkelsen,James Mitchell Ratliff +4 more
TL;DR: In this article, a method for automatically terminating or resuming backup copy sessions after an abnormal interrupt or reset notification occurrence during a backup copy process is presented, where a status indication is entered into activity tables associated with a plurality of storage subsystems and devices within a data processing system.
Patent
Method and system for incremental time zero backup copying of data
TL;DR: Backup copying of designated datasets representing a first selected point in time consistency may be performed in a data processing system on an attached storage subsystem concurrent with application execution by first suspending application execution only long enough to form a logical-to-physical address concordance, and thereafter physically backing up the datasets on the storage subsystem on a scheduled or opportunistic basis.
Patent
Synchronizing recovery log having time stamp to a remote site for disaster recovery of a primary database having related hierarchial and relational databases
TL;DR: In this article, a method and apparatus to synchronize recovery logs transmitted to a remote site for recovering related databases having different logical structuring is presented, where the related databases are a hierarchial structured database such as IMS and a relational structured DB2.
Patent
Forming consistency groups using self-describing record sets for remote data duplexing
Robert Frederic Kern,Ronald Maynard Kern,Gregory E. McBride,William Frank Micka,Claus William Mikkelsen,David Michael Shackelford,Robert Wesley Shomler +6 more
TL;DR: In this article, a remote data shadowing system provides storage based, real-time disaster recovery capability, where record updates at a primary site cause write I/O operations in a storage subsystem therein.
Patent
Concurrent switch to shadowed device for storage controller and device errors
TL;DR: In this article, a remote data shadowing between a primary and a secondary site uses a method and apparatus for swapping, or switching, host directed I/O operations from a primary data storage device to a secondary data storage devices in a remote copy duplex pair.
