Claim Text:
1. A system, comprising 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 comprising 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; share a point-in-time data consistency at the time-zero among all clusters within the DR family; create a snapshot of each backup copy stored to the one or more DR clusters, wherein each snapshot represents data stored to the one or more DR clusters at the time-zero; and perform DR testing using, in descending order of preference: a snapshot from a first cluster within the DR family, a snapshot accessed via the first cluster from a second cluster within the DR family when the first cluster does not include an up-to-date consistent snapshot, a backup copy from the first cluster, and a backup copy from the second cluster when the first cluster does not include an up-to-date consistent backup copy.
