Abstract:
Systems and methods for replicating database data and generating read-only copies of the replicated data in a clean shutdown state. For example, systems can include a tracking module (e.g., a filter driver) that monitors transactions from a database application to a source storage device to generate log entries having at least one marker indicating a known good state of the application. The systems further include a computer coupled to a target storage device comprising a database and log files. The computer processes the transactions, based on the log entries, to replicate data to the target storage device; performs a first snapshot on data stored in the database and log files; replays into the database data stored in the log files; performs another snapshot on the database; and reverts the database back to a state in which the database existed at the time of the first snapshot.
