Abstract
Snapshots may be remotely replicated asynchronously from a first LSU (R) on a first storage system (A) to a second replica LSU (R) on a second storage system (A). The storage system Amay open a consistency window to suspend initiating processing of new write operations received on A. While the consistency window is open, Amay: take a first snapshot, SS, of R; record, in association with the first replication cycle, an indication to replicate SSon A; and initiate a next replication cycle to record write operations of the next new write requests to be received from hosts. After initiating a next replication cycle, Amay close the consistency and transmit the first replication cycle to A. Amay apply the write operations of the first replication cycle to R, and then take a second snapshot SSof R, which should be a replica of SS.
