摘要： It has been impossible in prior art to copy every piece of data that is stored in a virtual volume. A management computer of this invention receives a copy request that designates a real storage area as a copy source, selects a virtual storage area that is associated with plural real storage areas as a copy destination virtual storage area, and judges whether or not a copy source virtual storage area and the copy destination virtual storage area are allocated to real storage areas. Based on a result of the judging, the management computer gives an instruction to copy data that is stored in the copy source real storage area to a copy destination real storage area, and keeps information about a replication relation between the copy source real storage area and the copy destination real storage area on which the data copy has been performed.

摘要： The present invention aims at preventing loss of the most recent data even if backup processing ends abnormally.A computer system includes: a first storage system having a data storage extent for storing data sent from a host computer; a second storage system having at least one actual replicated data storage extent associated with the data storage extent; an archive appliance having a storage medium associated with the replicated data storage extent in the second storage system; a data copy unit for controlling copy processing for reading data from the data storage extent in the first storage system and writing the read data to a first actual replicated data storage extent in the second storage system in accordance with specific configuration information; and a connection switching unit for changing the specific configuration information so that a second actual replicated data storage extent, instead of the first actual replicated data storage extent, is associated with the data storage extent.
摘要翻译：本发明的目的在于防止最近数据的丢失，即使备份处理异常结束。计算机系统包括：具有用于存储从主计算机发送的数据的数据存储区域的第一存储系统; 具有与数据存储范围相关联的至少一个实际复制数据存储范围的第二存储系统; 存档装置，具有与第二存储系统中的复制数据存储区域相关联的存储介质; 数据复制单元，用于控制从第一存储系统中的数据存储区读取数据的复制处理，并根据具体配置信息将读取的数据写入第二存储系统中的第一实际复制数据存储区; 以及连接切换单元，用于改变特定配置信息，使得第二实际复制数据存储范围而不是第一实际复制数据存储范围与数据存储范围相关联。
