When copying data, it is desired to securely execute data management by preventing violation of rules or leaking out of secret information by administrative error. 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 the 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.

Data processing method with restricted data arrangement, storage area management method, and data processing system

A computerstores boot information OAand application information APstored on a local disk, the information being respectively stored as an OSshared file group in a shared LUand as a APshared file group in a shared LUn+1. For personal information (including personal information of boot information or AP information), computerstores the information as a user personal file group in an personal LU. Computertransmits image outline information, LU information and file information for the sets of information stored in shared LU, shared LUn+1 and personal LUto an disk-image management server, where the information is stored in the storage deviceof the disk-image management server

Information storing method for computer system including a plurality of computers and storage system

The storage system creates a volume for storing information specific to a user, and a volume for storing software shared by a plurality of users, links these volumes on the basis of the software usage status of the users, and virtually builds one region and supplies same to the users.

Software management method for a storage system, and storage system

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.
