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 WEB service providing server can execute WEB service processing using data provided by an online storage service providing server, and leaking of data at the WEB service providing server can be prevented.A WEB service providing server 102 requests, in response to a service request from a client terminal 100, that an online storage service providing server 101 provides data that will satisfy the service request. The online storage service providing server 101 extracts content data from storage devices, encrypts the extracted content data, and provides the WEB service providing server 102 with storage service data composed of data including the encrypted content data and metadata. The WEB service providing server 102 constructs a WEB service screen according to the metadata and provides the client terminal 100 with the constructed WEB service screen.

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： Provided is a method of updating a mirror in a storage system that has a plurality of servers in which a mirror is created as a replica of a file system and the access load is balanced among a plurality of servers each having the mirror. Upon reception of an access request from a client computer, it is judged whether or not the client has a possibility of issuing at least one of update requests. In a case where it is judged that the client has a possibility of issuing at least one of update requests, a master from which a mirror is copied is selected. In a case where it is judged that the client does not have a possibility of issuing at least one of update requests, a mirror is selected. Then, access to the selected master or mirror is executed as requested.
