摘要： A backup control apparatus which references duplication management information which includes first stored location information indicating the stored location of first information resource and second stored location information indicating the stored location of a second information resource which duplicates the first information resource, and identifies, from among a plurality of information resources belonging to a backup region. The first information resource stored in the location indicated by the first stored location information, and a second information resource stored in the location indicated by the second stored location information corresponding to the first stored location information. The backup control apparatus replaces the identified second information resource with linked information indicating a link to the identified first information resource, and backs up the backup region in which the second information resource is replaced with the linked information.

摘要： Erroneous deletion of data due to a collision of digest information during data de-duplication using digest information is prevented. When backup data is stored on a backup server 1100, digest information of the backup data is generated and stored in a digest information management table 4200. In addition, when a backup data storage request is made to the backup server 1100, a digest information verification control sub-program 1127 generates digest information of data to be backed up, and performs verification against the digest information of the backed up data already stored on the backup server 1100. If, by this verification, it is found that backed up data having the same digest information is already stored, de-duplication is realized by reusing the existing backed up data without newly storing the data to be backed up.
摘要翻译：防止了使用摘要信息在数据重复数据删除期间由于摘要信息的冲突而导致的数据错误删除。当备份数据存储在备份服务器1100上时，生成备份数据的摘要信息并将其存储在摘要信息管理表4200中。此外，当对备份服务器1100进行备份数据存储请求时，进行摘要信息验证控制子程序1127生成要备份的数据的摘要信息，并对已经存储在备份服务器1100上的备份数据的摘要信息执行验证。如果通过该验证发现备份了具有已经存储了相同的摘要信息，通过重新使用现有备份数据而不重新存储要备份的数据来实现重复数据删除。

摘要： Difference information between two snapshots from a first point-in-time snapshot, which has been copied, to an Nth 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： There has never been disclosed a method of executing migration on a fine-grained basis than a file system basis in a manner that is transparent to clients in a storage system with a plurality of servers to which a global name space is applied. In a storage system with a plurality of servers and a disk subsystem, which is coupled to the plurality of servers, a file system in the disk subsystem is assigned a first identifier, which is unique throughout the storage system, at least one of directories contained in the file system is assigned a second identifier, which is unique throughout the storage system, and a file contained in the file system is assigned a third identifier, which is unique throughout the file system. The server identifies a file below the directory that has the second identifier by the second identifier and by the third identifier.

摘要： First, a duplicate elimination process based on a first duplicate elimination process, in which both a duplicate elimination effect and a processing load are low, is executed. Information related to a processing result of the duplicate elimination process based on the first duplicate elimination process is acquired prior to execution of a second duplicate elimination process, in which both the duplicate elimination effect and the processing load are high. Target data of the second duplicate elimination process is narrowed down based on the acquired information. The second duplicate elimination process is applied only to the narrowed down target data. As a result, an integrated duplicate elimination system with a lower processing load than in a conventional system is realized while attaining a high duplicate elimination effect.

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： An electromagnetic flowmeter using a square wave excitation method includes a differential amplifier which outputs a detection signal; an analog-digital converter which converts the detection signal into a digital detection signal; a timing control circuit which generates a sampling signal for sampling the digital detection signal; an calculation unit which executes a flow rate calculation process and a abnormality judging process at a same time. The flow rate calculation process acquires a flow velocity output signal by sampling the digital detection signal in a flat portion in a positive/negative excitation section. The abnormality judging process acquires a differential output signal by sampling the digital detection signal in a rising/falling portion in the positive/negative excitation section, and obtains a differential noise from the flow velocity output signal and a differential output signal, and judges abnormality of the exciting current by comparing a differential noise with a detection threshold level.
