Method and system for performing periodic replication using a log and a change map

摘要

Disclosed is a method and system for performing periodic replication using a log and a change map. According to one embodiment, a first region and a second region of a primary data volume are identified and a plurality of write operations to the primary data volume are tracked by tracking write operations to the first region utilizing a storage replication log and tracking write operations to the second region utilizing a storage replication change map. Thereafter, data associated with the plurality of write operations is replicated from the primary data volume to a secondary data volume utilizing at least one of the storage replication log and the storage replication change map.
