Abstract: In one aspect, a method includes making a first active buffer a passive buffer, generating a second active buffer to receive new I/Os, making a list of locations that need realignment in the passive buffer, flushing open I/Os at a splitter, reading I/Os which need realignment, discarding re-aligned I/Os for overwritten areas and sending the passive buffer to a replica site.
