    • PROBLEM TO BE SOLVED: To provide a backup data management device capable of performing processing to increase a generation number of backup.SOLUTION: A backup data management device manages backup data that is replication of data and/or programs for over an M generation. The backup data management device indicates M regions for recording backup data and M incremented regions for each backup processing in a cyclic fashion. When increasing a generation number to be managed to N which is larger than the generation number M, the present M regions are rearranged so as to start from the region indicated at present by an index in an order to perform backup.
    • 要解决的问题:提供能够进行处理以增加备份的生成次数的备份数据管理装置。 解决方案:备份数据管理设备管理备份数据,这些数据是针对M代的数据和/或程序的复制。 备份数据管理装置以循环方式指示用于记录备份数据的M个区域和用于每个备份处理的M个增加区域。 当将要管理的生成号码增加到大于生成号M的N时,现在的M个区域被重新排列,以便从当前以指示的区域开始,以便执行备份。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a backup data management device which can execute processing for reducing the number of generations of backup.SOLUTION: In the backup data management device which manages backup data which is duplication of data and/or a program for M generations (M is a natural number), M areas for recording the backup data and an index which instructs an area for recording are provided, wherein the index is incremented in each backup processing to perform a circulation instruction of the M areas and thus, the M areas are sequentially circulated and used to perform the backup processing, and when the number of generations to be managed is reduced to N (N is a natural number) which is smaller than M, N areas from before one to before N in a reverse order from an area which the index instructs at present are left, other areas are deleted, and the index is set to the area before N.
    • 要解决的问题:提供一种备份数据管理装置,可以执行减少备份次数的处理。解决方案:在管理备份数据的备份数据管理装置中,这是备份数据和/或用于M代的程序 (M是自然数),提供用于记录备份数据的M个区域和指示记录区域的索引,其中在每个备份处理中增加索引以执行M个区域的循环指令,因此,M 区域顺序地循环并用于执行备份处理,并且当将要管理的代数减少为小于M的N(N是自然数)时,以相反的顺序从一个到之前的N之前的N个区域 从目前指示的区域留下,其他区域被删除,索引被设置为N之前的区域。
