Abstract

Coordinating point-in-time snapshots among multiple computing platforms by receiving a notification from a first computing platform agent indicating a first computing platform snapshot time, receiving a notification from a second computing platform agent indicating a second computing platform snapshot time, determining that second computing platform snapshot time is later than the first computing platform snapshot time, notifying the first computing platform agent of the second computing platform snapshot time, and receiving from the first computing platform agent a report of any location in the first computing platform's data storage to which data were written after the first computing platform snapshot time and responsive to a write request that was made prior to or including the second computing platform snapshot time.
