    • A data processing system for allocating a plurality of peripheral storages to a plurality of users comprises a data processing device, a plurality of peripheral storages connected with the data processing device, a catalog control unit for setting on a table a total usage capacity of the usable space set by users including an active pool having a plurality of peripheral storages to which files are allocated and an inactive pool for holding files which are migrated from the active pool, a file allocating unit which sets the current usage capacity on a table depending upon the use of space of said active pool to compare the sum of the added space capacity inputted by users and the current usage capacity with said total usage capacity for deciding an error of allocation of the added peripheral storage when the sum is larger than the latter. A part of the peripheral storage in the active pool is set as spare volumes and the spare volumes are temporarily allocated when a failure occurs in the remaining part of the peripheral storages in the active pool or when there is not enough free space in the active pool.
    • 用于向多个用户分配多个外围存储器的数据处理系统包括数据处理装置,与数据处理装置连接的多个外围存储器,目录控制单元,用于在表上设置可用的 由用户设置的空间,包括具有分配了文件的多个外围存储器的活动池和用于保存从活动池迁移的文件的非活动池;文件分配单元,其根据所述活动池将当前使用容量设置在表上 使用所述活动池的空间将用户输入的增加的空间容量与当前使用容量的总和与所述总使用容量进行比较,以在总和大于后者时决定添加的外围存储器的分配错误。 活动池中的外围存储器的一部分设置为备用卷,并且当活动池中的外围存储器的剩余部分发生故障时或者当活动池中没有足够的可用空间时临时分配备用卷 。

    • The present invention relates to a method of backup sampling of multiwritten storage volumes, by which the backup sampling time is remarkably reduced by taking advantage that the same storage region exists in a plurality of volumes. Data from storage regions differing with respect to respective storage volumes is inputted concurrently and parallel, and the data is outputted to the output volumes according to the following: (a) data are output to the output volumes in the order of these storage regions; (b) data with information indicative of the order of these storage regions are output to the output volumes in the order of the storage regions upon completion of its data input; and (c) data from respective storage regions are output to different corresponding output volumes concurrently and parallel.
    • 本发明涉及一种对多个写入存储卷进行备份采样的方法,通过利用多个卷中存在相同的存储区域,可以显着地减少备份采样时间。 并行地并行输入来自相对于各个存储卷不同的存储区域的数据,并且根据以下方式将数据输出到输出卷:(a)以这些存储区域的顺序将数据输出到输出卷; (b)具有指示这些存储区域的顺序的信息的数据在其数据输入完成时以存储区域的顺序输出到输出体积; 和(c)来自相应存储区域的数据被同时并行地输出到不同的对应输出量。
