Systems and methods for managing replicated database data

A system for performing data management operations in a computer network environment, the system comprising:

• a database application configured to execute on a source computer;
• a first storage device coupled to the source computer to receive data transactions from the database application;
• at least one module configured to monitor the data transactions and to generate a plurality of log entries based on the data transactions, at least one of the plurality of log entries having a marker indicative of a time of a known good state of the database application;
• a second storage device comprising a target database and target transaction log files;
• and
• a target computer coupled to the second storage device and configured to:
• process, based on the plurality of log entries, the data transactions to replicate data to the second storage device,
• perform a first snapshot operation on data stored in both the target database and the target transaction log files to create a first snapshot, the first snapshot being indicative of stored data from the database application in a dirty shutdown state that prevents the first snapshot from being read or otherwise accessed by applications other than the database application, a stored indication of the dirty shutdown state being associated with the first snapshot,
• following the first snapshot operation, replay into the target database data stored in the target transaction log files such that the data stored in the target database following the replay becomes out of sync with the data stored on the first storage device,
• following said replaying, perform a second snapshot operation on at least a portion of the target database to create a second snapshot, the second snapshot being indicative of stored data from the database application in a recoverable and clean shutdown state, and
• revert, following the performance of the second snapshot, the target database back to a state in which the target database existed at the time of said performing the first snapshot wherein the data stored in the target database following said reverting is re-synchronized with the data stored on the first storage device, wherein the second snapshot can be read or otherwise accessed without the use of the database application.
