Abstract
In one embodiment, a system includes a processor and logic configured to create a backup copy of data stored to one or more production clusters and store the backup copy to one or more disaster recovery (DR) clusters. Moreover, the logic is configured to establish a time-zero in the DR family and create a snapshot of each backup copy stored to the one or more DR clusters. Each snapshot represents data stored to the one or more DR clusters at the time-zero, and each snapshot is a point-in-time flash copy of at least a user data portion of all virtual tapes of the one or more DR clusters with the proviso that the snapshot does not include a metadata portion of the virtual tapes. The logic is further configured to share a point-in-time data consistency at the time-zero among all clusters within the DR family.
