摘要： Difference information between two snapshots from a first point-in-time snapshot, which has been copied, to an N.sup.th point-in-time snapshot, which constitutes the latest point-in-time snapshot, is acquired to a memory module. The memory module stores two or more pieces of difference information. The two or more pieces of difference information comprise difference information that shows the difference between a first point-in-time snapshot and any snapshot other than the first point-in-time snapshot of N snapshots. Copy difference information, which is information that shows the difference between the first point-in-time snapshot and a specified snapshot from among N snapshots, and which is used in copying the specified snapshot, is created on the basis of the two or more pieces of difference information.

摘要： In order to access a distributed file system (DFS) of the present invention using a conventional protocol such as the one for an NFS or a CIFS without making a modification on a client side, a gateway unit for receiving a conventional protocol and performing processing in conformity the protocol is provided for a DFS server. The gateway unit emulates a directory structure in a file system such as the NFS or CIFS. When the DFS is a write-once read-many file system, update processing is converted into processing for creating a new generation file, and reference processing is converted into access to a latest generation file in a generation-managed file group. The gateway unit then accesses a DFS file via a DFS processing unit.

摘要： A storage system conducting remote copy functions such that, when data is updated at a local site, contents of the update can be referred to in real time by storage at a remote site. A disk-control unit at a remote site receives file data written in accordance with an update of a file in a storage system at a local site and a history of the file-management information from the storage system at the local site and stores the data and the history. A file-system processing unit refers to the history and updates the file-management information in a file-system cache in accordance with the update of the file in the storage system at the local site. When a client issues a read request, the file-system processing unit refers to the file-management information updated in the file-system cache and transfers the contents of the update of the file to the client.

摘要： Provided is a computer system, which executes migration after confirming that a retention term of an information resource stored in the computer system can be guaranteed at a migration destination. In a storage system including a control module, a disk drive for storing data, and a time information module for managing time information including a time, the control module obtains first time information from another storage system connected via a network, obtains second time information from the time information module, calculates a difference value between the first time information and the second time information, and in the case where the calculated difference value is smaller than a predetermined threshold, moves the data stored in the disk drive to another storage system.

摘要： A disk system which, when a variable-length disk is emulated using a fixed-length disk, makes it unnecessary to perform extra disk accesses at the time of performing a reading/writing operation the fixed-length disk. The disk system includes an upper system that accesses data with the use of a variable-length formatted form, a disk control unit emulating the variable-length disk and performing control of the fixed-length disk, and a fixed-length formatted disk unit. A storing region in the disk unit is separated into two regions. Count areas in all CKD records are stored into one of the regions, and key areas and data areas in all the CKD records are stored into the other region. The count areas in all the CKD records, which have been stored in the one of the storing regions, are stored into a cache memory in the disk control unit. When an access is executed from the upper system to the disk unit, the count areas stored in the cache memory are referred to so as to search an object record. This allows an access to the disk unit to be executed only to the objective record thus searched.
