摘要： PROBLEM TO BE SOLVED: To efficiently use a logical unit in a storage apparatus used by a computer to thereby restrain the increase of a storage capacity cost. SOLUTION: The storage apparatus includes an external logical unit as a target of a plurality of host apparatuses, and an internal logical unit allocated to the external logical unit. The internal logical unit includes a shared logical unit having shared files shared by the plurality of host apparatuses, and an individual logical unit having individual files used by each of the plurality of host apparatuses. Upon receipt of a write request from the host apparatus, the storage apparatus performs data matching by comparing write data depending on the write request with data stored in the shared logical unit at a predetermined management block unit. As a result of the comparison, the storage apparatus stores a matching data block in the shared logical unit, and stores a non-matching data block in the individual logical block.

摘要： PROBLEM TO BE SOLVED: To provide a computer system and a virus scan method which fully scans a logical volume of a "SUTOSEN" PC with high frequency, while reducing the number of virus scan devices. SOLUTION: The computer system includes a primary volume storing data from a personal computer, a snapshot volume storing the status of the primary volume at an arbitrary point of time, and a save volume storing an updated memory area in the primary volume as information on an updated block address by reflecting data update state in a bitmap corresponding to a memory area in the primary volume. The computer system detects only an updated file in the primary volume from the snapshot volume and the save volume, creates an update volume for storing a relevant updated file, and thereby executes a virus scan for the update volume.

摘要： PROBLEM TO BE SOLVED: To provide an image disclosing system allowing disclosure control. SOLUTION: This image registering device 1 extracts a file attribute of an original image file as disclosure control information (S014), when registering image data on an image disclosing server 3, prepares transmission data with the disclosure control information added to the image data (S015), and transmits it to the image disclosing server 3. The image disclosing server 3 rejects the registration when nondisclosed, according to a disclosure policy defined preliminarily, using the disclosure control information as a key, and allows the registration when permitted to be disclosed (S101). An access identifier is notified to a registered person and an accessing person in every access, in the image data set to require an approval of the registered person in the every access when disclosed, on the policy, the approval is judged by the registered person, and the disclosure is executed after a result of the judgement is approved.

摘要： PROBLEM TO BE SOLVED: To provide a storage device which records data write operations as journal information, reduces the journal information without completely overwriting the previously written data with the new data, and can perform strict step by step recovery. SOLUTION: Journal information is divided into journal data information in a block unit and journal log information including map information which refers to the journal data information, and then they are stored into a journal storage area. If there is a piece of journal log information that has the same block content of a piece of journal data information between pieces of journal log information, map information of new journal log information is rewritten so as to refer to blocks which have the same content as blocks referred to by map information of old journal log information. Thereby, redundant journal data information is reduced in a block unit without ruining operation contents indicated in journal log information to reduce journal information.

摘要翻译：要解决的问题：为了提供将数据写入操作记录为日志信息的存储装置，减少日志信息而不用新数据完全覆盖以前写入的数据，并且可以执行严格的逐步恢复。
解决方案：日记信息分为块单元的日志数据信息和日志日志信息，包括参考日志数据信息的地图信息，然后将其存储到日志存储区域中。如果有一条日志日志信息在日志日志信息之间具有相同的日志数据信息的块内容，则重新写入新日志日志信息的地图信息，以便参考具有相同内容的块旧日志日志信息的地图信息所引用的块。从而，冗余日志数据信息以块为单位被减少，而不会破坏日志日志信息中指示的操作内容以减少日志信息。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To shorten the time to start a diskless computer which is not equipped with storage.
SOLUTION: At the receiving of the reading request of a predetermined logical address(LBA) from a diskless PC 1002, a data transfer control part 1008 of a cache device 1004 inquires for the storage location of access pattern information to an IP name server device 1017, and acquires access pattern information. The sequence of a reading request is generated according to the access pattern information, and a reading request to an IP storage device 1016 is issued, before the previous issued reading request is ended; and the reading data from the IP storage device are stored in a cache memory part 1005 as necessary. A data transfer control part 1008 transfers data necessary for starting, from the cache memory part 1005 of the cache device 1004 to the diskless PC 1002.

摘要： PROBLEM TO BE SOLVED: To provide a network storage system for executing the update of data stored in a storage device to be accessed through a network in a state of presence of a computer terminal (PC) being connected to the storage device. SOLUTION: A storage device is connected to a PC through user identification by a user management server 7. When it is necessary to update data stored in the storage device, a storage management server 8 copies copy origin data to another copy destination storage device, and updates the data at the copy destination. As for a user who is supposed to connect to the copy origin storage device, the registration information of the user management server 7 is changed so as to be connected to the copy destination storage device afterwards. As for a user who is still being connected to the copy origin storage device, the user is notified that the data update of the copy origin storage device has ended, and urged to reconnect to the copy destination.
