  • Patent number: 12333174
    Abstract: Security is improved when creating a remote copy pair while suppressing performance deterioration of the overall system. In a data management system 1, when a user logs in, a first storage (main site storage 20) uses an external authentication server 50 to authenticate the user's access to its own storage and retains issued authentication information. Subsequently, when a command instructing a creation of a remote copy pair of a first volume (P-VOL) of the first storage and a second volume (S-VOL) of a second storage (sub site storage 40) is issued based on the user's operation, the first storage sends a command to the second storage by appending the authentication information, and the second storage uses the authentication information and requests the external authentication server 50 to authenticate the user's access to its own storage and, when the authentication is successful, the first or second storage starts synchronization of data between the pair volume.
