摘要： Provided is a technology in which: a request-source storage device provides a request-source server device with a storage area of a disk drive as at least one logical volume; the request-source server device determines, upon receiving a request to back up data stored in a first logical volume, whether a second logical volume which constitutes a copy pair with the first logical volume is present in the request-source storage device; the request-source server device requests, upon determining that the second logical volume is not present, the request-source storage device to produce the second logical volume; and the request-source server device transmits a request to execute a process to back up data stored in the existing or produced second logical volume to the backup storage device to the request-destination server device. Accordingly, data to be stored in a NAS not locally coupled to a backup device is appropriately backed up.

摘要： In a file server for suppressing power consumption of a storage apparatus, when a file sharing program receives a file access from a client, the program references a mapping table. The program addresses the access to the target file in the volume of a RAID group where the target file is stored. A coupling-request reception program memorizes a coupling time for each user into a coupling history table. A grouping program applies a grouping to users whose coupling time-zones are similar. A data transfer program transfers, into the same RAID group, data of the files associated with the grouped users, thereby collecting the data into the same RAID group. Thus, the time-zone when no access is made to the RAID group (i.e., non-coupling time-zone) can be made longer. Accordingly, a spin-up/down request program makes a spin-down request to the RAID group in the non-coupling time-zone.

摘要： According to the prior art load distribution method, there was a drawback in that the time required from discovery of increase of load to the completion of countermeasures was long. In particular, upon receiving migration of data from other file devices, it was necessary to equalize not only the load accompanying normal processes but also the load accompanying the data migration processes. In a file system receiving migration of data from a plurality of file devices, a plurality of virtual NAS (VNAS) is provided within the file storage subsystem, and an associated VNAS for executing data migration from file devices and accesses from clients is respectively associated with each file storage subsystem. Then, the state of each VNAS is defined based on the state of progress of data migration in the file storage subsystem. According to the defined state, load distribution among VNAS is performed.

摘要： An erasure declaration-related write request is received. In cases where, in response to the erasure declaration-related write request, erasure-corresponding data elements which are data elements corresponding to an erasure target and which are stored in a storage area A in the first logical volume are overwritten with erasure data elements which are data elements signifying erasure at or after the snapshot acquisition time point, the storage area A is associated with a storage area B in which encrypted data elements corresponding to the erasure-corresponding data elements stored in storage area A are stored.

摘要： A file is rapidly restored with minimal storage consumption when a file access request is made by the user. When file restoration takes place, a second server apparatus 3b transmits a directory image, which extends from the top directory to a predetermined lower level, of a directory image configured in a file system of a first server apparatus 3a at a date and time associated with a restoration destination directory among the data of files stored in a second storage apparatus 10b, to the first server apparatus 3a, and the first server apparatus 3a restores the directory image to a first storage apparatus 10a. If a request is sent from the first server apparatus 3a, the second server apparatus 3b reads an additional directory image from the second storage apparatus 10b and transmits the image to the first server apparatus 3a.
