A method for remote asynchronous volume replication and apparatus therefore are disclosed. Asynchronous replication is applied to deal with data changes on the source volume on the local site incurred by Host IO requests. In coordination with the “point-in-time differential backup” technology, the data is subjected to be backuped to Source BAS on the local site (backup-on-write operation) only when the original data being written into the block of the source volume is different from the data of the corresponding block of the destination volume on the remote site. As a result, once a new data is written into the source volume completely, the host will be responded that its Host IO request is completed. Therefore, the data necessarily transmitted to the destination volume on the remote site can be minimized, and the problem of remote data transmission limited by network bandwidth can be prevented effectively, thereby keeping the operation performance of the storage system at a better level.
