SYSTEMS AND METHODS FOR MONITORING APPLICATION DATA IN A DATA REPLICATION SYSTEM
First Claim
1. A method for monitoring a computer application executing on a source system to perform data replication, the method comprising:
- populating a first log file with data entries indicative of data operations sent by a computer application executing on at least one source computer to a file system;
identifying a recoverable state of the computer application; and
inserting in the first log file a marker identifying the recoverable state of the computer application, wherein the marker indicates a consistency point to a replication system to perform a snapshot of replicated data in the replication system based on the recoverable state of the computer application on the source computer.

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.

12. A system for generating application data for use in a data replication environment, the system comprising:
-
a monitor module executing in one or more computer processors, wherein the monitor module is configured to monitor data write operations of a computer application executing on at lest one source computer, and to generate first log entries based on the data write operations of the computer application, the monitor module being further configured to generate a second log entry indicative of a recoverable state of the computer application; and at least one log file in communication with the monitor module and configured to store the first and second log entries, wherein the second log entry is indicative of the recoverable state of the computer application, and wherein the second log entry indicates a consistency point to a replication system to perform a snapshot of replicated data in the replication system based on the recoverable state of the computer application on the source computer. - View Dependent Claims (13, 14, 15, 16, 17)
