Abstract
The invention is directed to techniques for managing a data set stored on a host computer that is in communication with a data storage assembly. A data manager on a host computer copies the data set to a synchronous copy of the data set stored on the data storage assembly and establishes a synchronous relationship between the data set and the synchronous copy. The data manager of the host computer can split the synchronous copy from the data set and generate a duplicate copy of the synchronous copy. Then the data manager can reestablish the synchronous relationship between the data set stored on the host computer and the synchronous copy stored on the data storage assembly.
