摘要: Disclosed are systems, computer-readable mediums, and methods for receiving a start replication message to replicate source volume replicated volume. A system forwards I/O requests the replica server. data structure associated with is initialized. write request received from system. The written updated. Source metadata received. compared prior point-in-time image of determine blocks that have changed since first block determined not be retrieved based upon structure. second
