A memory stores common identification information that is shared between a plurality of information provision institutions for identifying a person. A processor assigns the common identification information to personal information transferred to a storage device from a plurality of operation databases respectively of the plurality of information provision institutions. Then, the processor generates confidentialized personal information by confidentializing the personal information to which the common identification information has been assigned.

Information processing apparatus, information processing system and information processing method

A metadata processing unit acquires the first metadata from a first data storing unit at a first frequency and makes a second data storing unit store the first metadata. A file data processing unit specifies, based on the update history of the first metadata, second metadata that is updated on and after the last acquisition date and time of second file data stored in the second data storing unit, acquires the first file data associated with the specified management data at a second frequency that is lower than the first frequency, and makes the second data storing unit store the first file data. A switching unit switches a read/write process that is performed by using the operation data stored in the first data storing unit such that the read/write process is performed by using the second metadata and the second file data in the second data storing unit.

Information processing system, information processing apparatus, and information processing apparatus control method

A controlling device: receives state information indicating the state of a first storage region and the state of a second storage region for mirroring the first storage region; detects an error of an input and output process executed on the first storage region; executes, in response to the error, a first process if the first storage region is in a read-write mode, the first process including determining the states of the first and second storage regions, and selecting, based on the determined states, either one of executing the input and output process on the second storage region or stopping the input and output process executed on the first and second storage regions; and executes, in response to the error, a second process if the first storage region is in a read-only mode, the second process including executing the input and output process on the second storage region.

Controlling device, managing device, storage system, control method, management method, and non-transitory computer-readable storage medium for mirroring data

A storage system manages initialization status of a storage area block by block. The storage system allows reception of an access request indicating data write to Storage Area #, which is a part of an uninitialized block. Upon receiving the access request, the storage system writes data to the designated Storage Area #without initializing Storage Area #, and initializes, of the uninitialized block, Storage Area #not designated by the access request. The storage system determines that initialization of the uninitialized block has been completed with the data write to Storage Area #and the initialization of Storage Area #.

Data access method and data access apparatus for managing initialization of storage areas

A storage processing apparatus controls a second volume of a second virtual storage device storing a duplicate of a first volume of a first virtual storage device, the storage processing apparatus including a memory that stores a first identifier of the first volume received from the first virtual storage device; and a controller that establishes the first identifier stored in the memory as a second identifier of the second volume, and reports the first identifier established by the establishing in accordance with a notification request of the second identifier.

Storage processing apparatus, computer-readable recording medium storing program for controlling storage, and storage system

A storage system includes a first control apparatus; at least one second control apparatus managed by the first control apparatus; and a storage unit accessed by the second control apparatus. The second control apparatus determines based on detection of an error of an input/output process for storage in the storage unit whether the storage is in a blocking state, executes a resumption process of the input/output process when the storage is in the blocking state, judges whether an error occurrence frequency of the input/output process is at least a predetermined value, when the storage is not in the blocking state, and transmits to the first control apparatus, a blocking process request for the storage, when the error occurrence frequency is at least the predetermined value. The first control apparatus executes a blocking process and an error process of the storage, based on reception of the blocking process request.

Storage system, control apparatus, computer product, and control method

The first storage area stores original data of an update target that is to be updated by a host. The controller divides data to be written over the original data of the update target stored in the first storage area into a plurality of pieces of update data and thereby distributes the plurality of pieces of update data for each of successive addresses. The second storage area stores the plurality of update data distributed by the controller. The third storage area stores information in which an update area address, which is an address of the first storage area to be overwritten by the plurality of pieces of update data of the original data of the update target, is associated with a storage destination address, which is an address of the second storage area that has stored the plurality of pieces of update data.

Storage control device and control method

A storage control device configured to control a storage device includes a first disk which is in active state and a second disk which is in standby state. The storage control device includes a communication unit and a control unit. The communication unit transmits a read-out request or a write request to the storage device and receives a response to the read-out request or the write request from the storage device. The control unit controls the communication unit so that the communication unit transmits a rotation start command which instructs a start of rotation of the second disk to the storage device, when a time to the point when receiving the response to the read-out request or the write request transmitted to the first disk which is in active state is longer than a predetermined threshold.
