ABSTRACT:
Disclosed is a method and system for performing periodic replication using a write-ordered log. According to one embodiment, a plurality of write operations to a primary data volume are tracked using a write operation log and then data associated with the plurality of write operations is replicated to a secondary data volume by coalescing the plurality of write operations utilizing the write operation log and transferring data associated with the plurality of write operations to the secondary data volume. According to another embodiment the described tracking includes storing metadata associated with the plurality of write operations within the write operation log. In another embodiment, the described coalescing includes identifying a non-overlapping portion of a first write operation and a second write operation of the plurality of write operations utilizing the metadata.
