Methods and apparatus for optimal journaling for continuous data replication

Image Number 17 for United States Patent #7516287.

Methods and systems for continuous data replication, including receiving a write transaction from a production site, the write transaction including raw data (RWNEW), a size indicator (SZ1) for the size of the raw data, and a start address (ADD1) for writing the raw data, copying the raw data (RWNEW) into a first journal data stream at a current journal address (JADD1), and copying the size indicator (SZ1), the start address (ADD1) and the journal address (JADD1) into a first journal meta-data stream.
