Abstract

When copying corporate business data, etc., it is desired to execute data management excellent in security protection by preventing violation of rules or leaking out of secret information attributed to wrong operation of an administrator. For this purpose, in a data processing method, for each storage area such as a volume in a storage device or a logical volume, a possible data arrangement range of data included in such storage area is stored. In addition, range information is defined for a copy-destination storage area. Then, when copying data in a storage area, a judgment is made as to whether or not the range information of the copy-destination storage area is within the possible data arrangement area of the data. If the range information is within the possible data arrangement area, copying will be executed. If the range information is not within the possible arrangement area, the copy processing will not be initiated.

Claims

1. A storage area management method of a computer system having a storage area to store data, said method comprising steps of:

defining a range in which the data can be arranged (hereinafter the range in which data can be arranged is referred to as the “

possible data arrangement range”

);

defining range information to judge whether or not data to be stored can be arranged in said storage area;

judging whether or not said possible data arrangement range is within the range indicated by said range information.

outputting whether or not said possible data arrangement range is within the range indicated by said range information.
