    • Proposed are: a high-performance and highly-reliable snapshot management apparatus and method, and storage system, that can prevent the adverse influence of overhead when they retain a multiplicity of snapshots. An operational volume is set in a storage area provided by a first storage apparatus and a difference volume is set in a storage area provided by a second storage apparatus. In response to data writing to the operational volume, difference data is saved in the difference volume and a management table for it is created, and each snapshot is managed according to the management table. This management table is divided according to one or more snapshots in accordance with the snapshot creation time; and if there is more than one management table, the second and any following management tables store specified inheritance information to inherit the content of the preceding management tables.
    • 提出的是:高性能和高可靠性的快照管理设备和方法以及存储系统,可以防止在保留多个快照时开销的不利影响。 在由第一存储装置提供的存储区域中设置操作量,并且将差异体积设置在由第二存储装置提供的存储区域中。 响应于对操作卷的数据写入,将差异数据保存在差异卷中,并创建管理表,并根据管理表对每个快照进行管理。 该管理表根据快照创建时间根据一个或多个快照进行划分; 并且如果存在多个管理表,则第二和任何以下管理表存储指定的继承信息以继承前述管理表的内容。
