Claim:
A method of storing recovery data, comprising: a host processor writing data to a local storage device; the host processor causing the local storage device to accumulate chunks of data corresponding to writes by the host processor, wherein data written after a first time and before a second time is associated with a first chunk of data and data written after the second time is associated with a second chunk of data different than the first chunk of data; transmitting the first chunk of data from the local storage device to a remote destination while accumulating writes for the second chunk of data; following transmitting the first chunk of data, sending a message to the remote destination; in response to receiving a reply to the message, transmitting the second chunk of data to the remote destination; providing synchronous data from the local storage device to a local destination; and the host processor causing an indicator to be provided to the local destination in connection with receiving the reply from the remote destination.
