Abstract
A storage apparatus includes a second volume which stores data serving as a copying source of data to be stored in a first volume, serving as a data copying destination in another storage apparatus, a session establishing unit which establishes a session between the second volume and the first volume, and a copy directing unit which directs a volume, including a free area, in the other storage apparatus such that data equivalent to the data to be stored in the first volume is copied, in response to a copy setting command issued by a server.
Claims17
A storage apparatus including a remote data copy function, the storage apparatus comprising:
- a second volume which stores data serving as a copying source of data to be stored in a first volume serving as a data copying destination in another storage apparatus;
- a session establishing unit which establishes a session between the second volume and the first volume;
- and
- a copy directing unit which directs a volume, including a free area, in the other storage apparatus such that data equivalent to the data to be stored in the first volume is copied, in response to a copy setting command issued by a server.
A backup apparatus including a remote data copy function, the backup apparatus comprising:
- a first volume which stores data equivalent to data stored in a volume serving as a copying source in another storage apparatus;
- a copy instruction receiving unit which receives a copy setting instruction issued by a server, from the other storage apparatus with which the server is in communication;
- and
- a local-copy setting unit which makes a setting, based on the copy setting instruction, such that data which is equivalent to the data stored in the first volume is copied to a volume including a free area.
A backup method including a remote data copy function, the backup method comprising:
- establishing a session between a first volume, serving as a data copying destination in another storage apparatus and a second volume which stores data serving as a copying source of data to be stored in the first volume;
- and
- directing a volume including a free area in the other storage apparatus such that data equivalent to the data to be stored in the first volume is copied, in response to a copy setting command issued by a server.
A computer-implemented method, comprising:
- issuing a request for a local copying from a storage volume directly communicating with a server;
- and
- implementing the local copying by establishing a session between the storage volume and a remotely located area that is separate from the storage volume.
