Abstract
In one embodiment, a system includes a processor and logic integrated with and/or executable by the processor, the logic being configured to cause the processor to define a disaster recovery (DR) family, the DR family having one or more DR clusters accessible to a DR host and one or more production clusters accessible to a production host, wherein the DR host is configured to replicate data from the one or more production clusters to the one or more DR clusters, create a backup copy of data stored to the one or more production clusters, store the backup copy to the one or more DR clusters, establish a time-zero in the DR family, and share a point-in-time data consistency at the time-zero among all clusters within the DR family. Other systems, methods, and computer program products are presented for DR testing, according to more embodiments.
