Zusammenfassung:Aspects of the invention include a continuous availability for workload and site switches with no data loss at unlimited distances in an active-active sites configuration. A non-limiting example computer-implemented method includes synchronously replicating commit records of changed workload data, by a processor, from an active site to a bunker site upon a workload data commit. The method asynchronously replicates committed transactions on changed workload data, by the processor, from the bunker site to a recovery site.
