Abstract:
1. A method for copying data generated on a source system in a computer network, the method comprising: processing, with one or more routines, at least one log file having a plurality of log entries indicative of operations generated by a computer application executing on a source system, the operations being directed to data on a source storage device; copying at least portions of the log file to a destination storage device to create a second log file on the destination storage device; replaying, with the one or more routines, the log entries in the second log file on the destination storage device to create replicated data on the destination storage device; suspending said replaying on the destination storage device when the one or more routines encounters a consistency point marker in the second log file, the consistency point marker being indicative of a known good state of the computer application wherein the consistency point marker further comprises the time of the known good state of the computer application executing on the source system; performing a storage operation on the replicated data on the destination storage device when the replicated data represents the known good state of the computer application; and associating results of the storage operation on the replicated data on the destination storage device with the time of the known good state of the computer system executing on the source system.
