Abstract

See full text

In one embodiment, a system includes a processor and logic integrated with and/or executable by the processor. The logic is configured to cause the processor to determine which cluster within a disaster recovery (DR) family to access, via a DR host, a snapshot of data from based on a consistency of the snapshot in relation to data on one or more production clusters at a time-zero, cause the processor to allow access, via a first DR cluster, to snapshots on any of one or more DR clusters within a DR family, access the snapshot stored on the one or more DR clusters within the DR family only when the snapshot was made consistent with respect to data on the one or more production clusters within the DR family before a time-zero, and perform DR testing using the snapshot.
