FLASH COPY FOR DISASTER RECOVERY (DR) TESTING

摘要

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.

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; 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 wherein 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; and share a point-in-time data consistency at the time-zero among all clusters within the DR family.
