Systems and methods for performing data replication
First Claim
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.

Abstract
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.

11. A system for performing data management operations, the system comprising:
-
a first storage device that stores data write operations from at least one computer application at a first location at a first time; at least one module configured to monitor the data write operations and to generate first log entries based on the data write operations; a second storage device comprising second log entries wherein the second log entries comprise copies of at least a portion of the first log entries; and a replication module in communication with the second storage device and configured to; process the copied data write operations in the second log entries to create replicated data stored in a second location, associate the replicated data stored in the second location with the at least one computer application at the first location, wherein after the associating, the replicated data appears to be data existing at the first time on the first location. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
