Abstract
In one embodiment, a computer program product for disaster recovery (DR) testing includes a computer readable storage device having program code embodied therewith. The program code is readable and/or executable by a hardware processor to define a DR family including one or more DR clusters accessible to a DR host and one or more production clusters accessible to a production host, 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, create a snapshot of each backup copy stored to the one or more DR clusters, share a point-in-time data consistency at the time-zero among all clusters within the DR family and perform DR testing. The DR host is configured to replicate data from the one or more production clusters to the one or more DR clusters.
