  • Remote asynchronous mirror recovery
    Patent number: 7328319
    Abstract: For a highly available replication system, a process is presented whereby, after a successful failover from primary to replica, with the replica now being the new primary, and where, at a later time, the original primary is subsequently restored to operation, a subset close to the minimal possible subset of data that needs to be transferred between the new and original primaries can be computed.

  • Hybrid transaction/intent log for data replication
    Patent number: 7082446
    Abstract: A method whereby a transaction log is converted to an intent log and vice versa while the replication system is operating, thus allowing the replication system to operate primarily as a transaction log, but switch eventually to an intent log before an overflow condition of the transaction log occurs. The size of the hybrid log is tuned so that it remains a transaction log (with all the benefits) for commonly occurring small network outages but will convert to an intent log (and thus not overflow) if a prolonged outage occurs.
