Abstract:
Provided is a control method for an asynchronous remote copy system, the method including: fixing data in a secondary volume; determining a certain area in the secondary volume that contains data required to be copied to a primary volume from the secondary volume in which the data is fixed; copying the data in the certain area to the primary volume; and swapping the primary volume and the secondary volume for restarting the asynchronous remote copy.
