摘要： The performance of the analysis system is deteriorated because file content extraction processing is performed in the file aggregation server and in the analysis server and further because annotation data creation is performed in the file aggregation server. Therefore, the present invention solves the problem by providing a file aggregation server classifying files into analysis target contents, non analysis target contents, and content matched data, and providing only the analysis target contents to the analysis server. Since this method enables the analysis server to acquire the analysis target contents directly from the file aggregation server, the processing of extracting contents from the files becomes unnecessary, and the throughput of the entire analysis system is improved.

摘要翻译： 在文件聚合服务器和分析服务器中执行文件内容提取处理，进一步由于在文件聚合服务器中执行注释数据创建，所以分析系统的性能恶化。 因此，本发明通过提供将文件分类为分析目标内容，非分析目标内容和内容匹配数据，并且仅将分析目标内容提供给分析服务器来解决问题。 由于该方法能够使分析服务器直接从文件聚合服务器获取分析目标内容，所以从文件中提取内容的处理变得不必要，从而提高了整个分析系统的吞吐量。

摘要： In order to mitigate a load in communications among an integrated search server, a plurality of search users and a plurality of search servers in an integrated search system, in the present invention, when an integrated search is executed, first, information for narrowing down the search servers is obtained from each search server, and subsequently, the search servers are narrowed down based on this information, and search results are obtained from only the search servers which have been narrowed down. Thereby, there are advantageous effects of reducing memory usage of the integrated search server, and reducing unnecessary network traffic between the integrated search server and each search server.

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： In a computer system according to an embodiment of the present invention, a first slave server includes copy management information associating a master file system identifier with an identifier of a slave server including a copy of the master file system identified by the master file system identifier. The first slave server acquires a copy of a part of a master file system. The copy includes a stub-state object (file or directory). The first slave server searches the copy management information for a slave server to be queried regarding information for materializing the stub-state object. If the slave server to be queried includes the information for materialization, the first slave server materializes the stub-state object using the information for materialization acquired from the queried slave server.

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： A file server stores the storage management information and migration policy information. The storage management information includes the information that indicates a storage attribute for each storage apparatus. The migration policy information includes a plurality of information sets. Each of the information sets includes the information that indicates a condition of a file attribute and the information that indicates a condition of a storage attribute of a storage apparatus that is a migration destination. The file server specifies a migration target file, specifies a storage apparatus that conforms to the storage attribute condition that is indicated by the information set that includes the information that indicates a condition of a file attribute that conforms to of a file attribute of a target file based on the storage management information, and migrates a target file from a storage apparatus that has stored the target file to the storage apparatus that has been specified.
