Abstract
A method, system, and computer program product for determining a consistent point in time in a replication environment comprising determining periods of time that no IO was received from sources; wherein the periods are determined to account for differences between the clocks of the sources and the clock at a replication appliance, adjusting the periods of time that no IO was received by at least one delay factor, comparing the adjusted periods of time from the sources to determine a common period of time; wherein the common point in time denotes that each source was in a consistent state and marking the adjusted point in time as a consistent point in time in a journal.
