    摘要: This invention includes: a step (S1) of receiving a snapshot creation request from a client computer; a step (S3) of obtaining, upon reception of the snapshot creation request, a usage ratio of a second volume by the update differences; a step (S2) of obtaining a use history of the update differences in the second volume of the user; a step (S4, S5) of choosing, based on the usage ratio and the use history, one from differential snapshot in which the update differences of the first volume are written in the second volume and volume snapshot in which a third volume is synchronized with the first volume; and a step (S6, S7) of executing the chosen one of differential snapshot and volume snapshot. As a result, it is possible to economically use a differential volume by using differential snapshot in combination with volume snapshot.

    摘要: To provide a data protection method which allows data to be protected even when there is any access beyond administrator's intention. The data protection method for accepting an access request for a file stored in a file system of a storage device and referring or updating to the file based on the access request, includes the steps of: determining whether a current time is within a preset monitoring period; obtaining a snapshot of the file system when the time reaches the monitoring period (S101); and updating the file system with the snapshot when the time reaches end of the monitoring period (S106).

    摘要: Data is stored to a disk drive (4) in a directory path designated by a write request, and a directory path as a backup object and the directory path for the write request are compared with each other. When the directory paths match each other, the data is transferred to backup systems (3 and 5). In the case where the directory path for the write request is not the backup object, the data in the directory path is requested to be backed up when the directory path matches a preset condition.

    摘要: The present invention permits backup processing suited to data characteristics relating to backup target data by means of a method that is simple for the user. Data characteristic classification definition information, in which data characteristic IDs correspond with one or more data characteristic types respectively, and mapping information, in which backup destination server information corresponds with one or more data characteristic IDs respectively, are prepared. The backup source server 3 sets data characteristic IDs in each of the backup target files on the basis of metadata of designated backup target files and of the data characteristic classification definition information, and then determines backup destination servers 6A to 6C for each of the backup target files on the basis of the set data characteristic IDs and mapping information and transmits the backup target files to the determined servers 6A to 6C.

    摘要: Services are promptly resumed at the time of a failure recovery in an information processing system. Before a first server system 3a resumes service during the failure recovery, a second server system 3b sends the first server system 3a directory images of directories of a highest-level tier to a predetermined lower-level tier out of data of files stored in a second storage apparatus 10b, and the first server system 3a restores the directory images in a first storage apparatus 10a. When the request is transmitted from the first server system 3a, the second server system 3b reads an additional directory image from the second storage apparatus 10b and transmits the additional directory image to the first server system 3a. If a re-stubbing occurrence frequency is equal to or higher than a predetermined threshold, the second server system 3b suppresses transmission of directory images to the first server system 3a.

    摘要: The present invention concerns allocating files in storage apparatuses efficiently while satisfying requirements of the files. An information system 1 includes a first server system 3a coupled to a first storage apparatus 10a, a second server system 3b coupled to a second storage apparatus 10b, and a third server system 3c coupled to a third storage apparatus 10c. When the first server system 3a receives a data I/O not needing access to the entity of a file responds to the data I/O request using metadata of the file and when the first server system 3a receives a data I/O needing access to the entity of a file acquires the entity of the file from the second storage apparatus 10b or the third storage apparatus 10c to process the data I/O request. The first server apparatus determines the allocation target of the entity of the files on the basis of a requirement set for the files and information relating to configurations of the storage apparatuses 10.

    摘要: An object is to enable efficient shredding of recording media in association with migration. An information processing device (a server device 3) receives a data input/output request in a unit of a file transmitted from a client device 2, and performs writing and reading of data to and from a storage system 10 having a recording medium (hard disk drive 171) in which a file entity specified in the received data input/output request is stored in units of data blocks. The information processing device is communicatively coupled to a different storage device which is a migration destination of data. In the case where after the migration of certain data, different data is written in a data block of the certain data in an overlapped manner, the data block is not shredded if the data block is already shredded related to either of the overlapped certain and the different data after the migration.
