摘要

PPROBLEM TO BE SOLVED: To provide a method, a system and a program for managing the relationship between one target volume and one source volume. PSOLUTION: By at least one element representing a range of a sequential data unit in a volume, at least one relation item representing one relation, and at least one element pointer associating one element with one relation item, information related to an existing relationship between at least one source volume and one target volume is maintained in a memory. Further, when a new relationship between at least one target volume and at least one source volume is added, a new relation item representing the new relationship is added in the memory. Also, one new element pointer for each element is added so as to associate the new relation item with each element including a data unit included in the new relationship.

要解决的问题:提供一种用于管理一个目标卷和一个源卷之间的关系的方法,系统和程序。

解决方案:通过至少一个表示卷中顺序数据单元范围的元素,至少一个表示一个关系的关系项以及至少一个将一个元素与一个关系项相关联的元素指针,与现有信息相关在存储器中保持至少一个源卷和一个目标卷之间的关系。此外,当添加至少一个目标体积和至少一个源体积之间的新关系时,表示新关系的新关系项被添加到存储器中。另外,为每个元素添加一个新元素指针,以便将新关系项与包括新关系中包括的数据单元的每个元素相关联。
