Abstract
This invention provides a computing system in which multiple remote copy destination sites exist and, even if a failure occurs in a copy source volume in a remote copy source site, it becomes possible in at least one remote copy destination site to establish backup in which data must be determined at a certain point in time. The computing system of this invention is characterized by, before the in-storage copy function performing in storage copy in the remote copy source site, setting the pair status of the remote copy destination volume in at least one storage system in multiple remote copy destination storage systems and the remote copy source volume to the mode for terminating remote copy and, after the in-storage copy is completed, changing the above-mentioned pair status to the mode for starting remote copy.
