Abstract

A system and method for synchronizing a data copy that include a source volume having a data file stored thereon (72), the source volume for receiving write commands from a host (74), executing the write commands to generate an updated data file (76), and generating a record of the write commands (78). The system and method further include a secondary volume having a copy of the data file stored thereon, the secondary volume for receiving and storing data indicated by the write command record (82), wherein the copy of the data file and the data indicated by the write command record are available for use in generating a copy of the updated data file.
