    • A computer system for preventing data loss that 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; and 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. The system also has 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.
    • 一种用于防止数据丢失的计算机系统,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; 以及数据复制单元,用于控制从第一存储系统中的数据存储范围读取数据的复制处理,并且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范围。 该系统还具有用于改变特定配置信息的连接切换单元,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。

    • A computer system including a copy source volume and a copy target volume which may be selectably PAIRED or SPLIT. User management information stores: an entry indicating that a first user is permitted to effect a PAIR operation and a PATH operation; and, an entry indicating that a second user is permitted to effect a PATH operation. Operation management information indicates permitted PATH and PAIR operations in relation to each user and a volume's PAIR or SPLIT status, and stores: an entry indicating that the first user is permitted to effect the PAIR operation in which the PAIR status is PAIR, or is SPLIT WITH BACKUP DISABLED; and, an entry indicating that the second user is permitted to effect the PATH operations in which the PAIR status is SPLIT WITH BACKUP ENABLED. PAIR management information stores the PAIR status and the BACKUP ENABLED or DISABLED status.
    • 一种计算机系统,包括复制源卷和复制目标卷,其可选地配对或分页。 用户管理信息存储:指示允许第一用户执行对等操作和PATH操作的条目; 以及指示允许第二用户执行PATH操作的条目。 操作管理信息指示与每个用户相关的允许的PATH和PAIR操作以及卷的PAIR或SPLIT状态,并且存储:指示第一用户被允许实现PAIR状态为对等体的对偶操作的条目,或者是SPLIT 带备份禁用 以及指示第二用户被允许实现其中PAIR状态是SPLIT WITH BACKUP ENABLED的PATH操作的条目。 PAIR管理信息存储PAIR状态和BACKUP ENABLED或DISABLED状态。
