摘要： A storage system 103 carries out first and second de-duplication processes in response to receiving a write request from a client. First, a determination is made as to whether a write target data item overlaps with any of the stored data items of a part of a stored data item group, which is a user data item group stored in a storage device 209, and if so, the write target data item is prevented from being stored in the storage device. Second, a determination is made as to whether a target stored data item, which is not finished being evaluated as to whether it overlaps with the stored data item in the first de-duplication process, overlaps with another stored data item, and if so, the target stored data item or the same data item overlapping with the target stored data item is deleted from the storage device 209.

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： According to this invention, a computer system which provides a client node with a file system mounted into a virtual namespace, comprising: at least one file server which provides the file system; a root node which mounts the file system provided by the file server into the virtual namespace; and a network which couples the file server and the root node. The root node has an interface coupled to the network, a processor coupled to the interface, and a memory coupled to the processor. The root node is configured to: obtain access information set to a directory above a point in the virtual namespace at which the file system is to be mounted when mounting the file system into the virtual namespace; judge whether the obtained access information is to be inherited; and set, to the file system to be mounted, the obtained access information that is to be inherited.

摘要： A storage system configured to be applied to a broad range of access forms to the file and improve performance of file access control processing. The storage system may store a part of the access control information of a variable size in the basic attribute area of the file, and store the storage format information in the basic attribute area of the file or in the file system metadata area. At the time of processing the access to the file, with reference to the storage format information, the storage system may decode a part of the access control information into an access mask bit string as needed, and perform the preceding access control processing.

摘要： A computer apparatus which integrates at least two or more services of user management domains has a processor, a memory and an interface. The processor receives an access request, specifies an access source domain, specifies an access target domain, and judges whether the specified access source domain matches the specified access target domain. If the access source domain is different from the access target domain, the processor extracts a user ID of the specified access source domain from the received access request, and refers to ID conversion information indicating correspondence of user IDs between the user management domains whose services are integrated to convert the extracted user ID of the access source domain into a user ID of the specified access target domain. Thus, loads of configuration at the time of service integration are reduced.

摘要： Provided is a computer system containing plural storage systems which manages the bandwidth of the storage systems in accordance with storage area attributes. The computer system is characterized in that: a control unit incorporates related file information in metadata, the related file information containing information for identifying a second file which to be write-accessed in conjunction with access to a first file by a client computer, and an access type of the write access. The control unit refers to the related file information to obtain the second file and the access type when the first file is accessed by the client computer. The control unit reads, from the obtained second file stored in the disk device, data corresponding to the obtained access type, to store the read data in a cache memory.
