Systems and methods for performing data replication

摘要

Performing data management operations on replicated data in a computer network. Log entries are generated for data management operations of an application executing on a source system. Consistency point entries are used to indicate a time of a known good, or recoverable, state of the application. A destination system is configured to process a copy of the log and consistency point entries to replicate data in a replication volume, the replicated data being a copy of the application data on the source system. When the replicated data represents a known good state of the application, as determined by the consistency point entries, the destination system(s) may perform a storage operation (e.g., snapshot, backup) to copy the replicated data and to logically associate the copied data with a time information (e.g., time stamp) indicative of the source system time when the application was in the known good state.

1. A method for performing data management operations, the method comprising:
monitoring operations associated with a computer application, the operations operative to write data to a first location on a first storage device at a first time; storing information about the operations in a first log file on the first storage device; copying at least a portion of the first log file on the first storage device to a second log file on a second storage device; processing the second log file to create replicated data at a second location; generating a snapshot of the replicated data at a time after the second log file has been copied to the second storage device; and associating the snapshot of the replicated data with the first location wherein after the associating, the snapshot of the replicated data appears to be a snapshot of the data existing at the first time on the first location.
