Abstract
In one embodiment, a method for disaster recovery (DR) testing includes creating a snapshot of data based on a backup copy of data stored on one or more production clusters or a live copy of the data and storing the snapshot on more than one DR cluster within a DR family, determining which cluster within the DR family to access the snapshot from based on a consistency of the snapshot in relation to data on the one or more production clusters at a time-zero, accessing the snapshot of data stored on the determined DR cluster 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 the time-zero, and performing DR testing using the snapshot.
