Patent ID: 7487386

Claim:
A method comprising: generating a first replica data volume, the first replica data volume comprising a backup of initial source data; generating a second replica data volume, the second replica data volume comprising a backup of initial source data; generating a first flashcopy of the first replica data volume; generating at least a second flashcopy of the second replica data volume; performing a recovery of the first flashcopy to obtain a first recovered flashcopy; performing a recovery of the second flashcopy to obtain a second recovered flashcopy; receiving a request for initial source data from an application; exporting the initial source data from one of the first recovered flashcopy and second recovered flashcopy to the application based on the received request; determining whether one of the first replica data volume and second replica data volume has changed data; generating an updated first flashcopy based on the determination; generating an updated second flashcopy based on the determination; sequentially quiescing an export of the first recovered flashcopy; switching the first recovered flashcopy with the updated first flashcopy; and exporting the switched flashcopy.
