In a storage system that is connected via networks to a cloud system, which provides an object store, and backs up backup data of a predetermined volume as an object to the object store, the storage system includes a processor, and the processor is configured to determine whether the storage system stores a snapshot associated with a volume at a first point in time to be restored, and restore the volume at the first point in time using the snapshot when it is determined that the storage system stores the snapshot.

Data control apparatus and data control method

A management server stops a sub-server in advance and prepares a sub-storage that operates in response to a request from the sub-server at the time of transition at which a business process of using data stored in a regular storage is performed in the sub-server. The management server recovers data using recovery data stored in an object storage and stores the data in the sub-storage and starts the sub-server.

Storage system and management method

Acquiring a snapshot of a logical volume involves generating snapshot-related catalog information including at least a location for storing actual data in the snapshot and a reference destination for identifying another snapshot in parent-child relation to the snapshot, and storing the actual data in the snapshot to the physical storage device and/or to the cloud service. In a case where at least one of a plurality of snapshots is to be designated and restored, catalog information is referenced to identify the storage location of the actual data and acquire the actual data stored in the physical storage device and the actual data not stored in the physical storage device from the cloud service.

Storage system and method of restoring storage system

To back up stored data of a storage device installed on-premise to a storage service provided by a public cloud more reliably and efficiently. A storage system according to the invention includes a storage device having first storage logical volumes (LDEVs), and a storage device having second storage LDEVs. When stored data of a first LDEV and stored data of a second LDEV are synchronized with each other, network conditions in a transfer path from the storage device to the public cloud and in a transfer path from the storage device to the public cloud are observed. The first LDEV or the second LDEV is selected as a backup source based on the network conditions.

Storage system and data backup processing method in storage system

In failover processing, a CPU restores data stored in a first volume to a second volume of a storage system, associates a unique ID of the first volume with the second volume, and stores the unique ID associated therewith in a memory. After the failover processing is completed, the CPU manages an update difference management bitmap indicating an updated content with respect to data stored in the second volume. The CPU transmits, in failback processing, update data updated after the failover processing among the data stored in the second volume to the first volume identified by the unique ID associated with the second volume based on the update difference management bitmap.

Computer system and data control method

An image capturing unit in an inspection system for performing an inspection target appearance inspection, the image capturing unit comprising, an image capture unit, an illumination unit arranged in a periphery of the image capture unit, and a protective unit covering the image capture unit and the illumination unit, wherein the protective unit includes a plate-like member configured by a first planar portion and a second planar portion being connected through a bent portion bent in a dog leg shape, and the image capture unit is located on a back side of the first planar portion.

Image capturing unit and inspection system

An administrative terminal receives designation of generation target data and of a generation destination storage device and identifies data similar to the target data. The terminal calculates a first predicted time expected for transmitting the target data from a storage device holding the target data to the generation destination storage device, and a second predicted time expected to be required for a second transmission process of transmitting the similar data from an object storage service to the generation destination storage device and of transmitting difference data between the target data and the similar data from the storage device holding the target data to the generation destination storage device. If the second predicted time is shorter than the first predicted time, the administrative terminal performs the second transmission process to transmit the similar data and the difference data to the generation destination storage device to generate the generation target data therein.

Predictive optimization system and method for data generation and transmission in storage networks

A storage apparatus includes: a flash memory that provides a storage area; a controller that controls writing and reading of data to and from the storage area; and a buffer memory that temporarily stores data to be written in the storage area, in which the controller selects one compression method from a first reversible compression method and a second reversible compression method based on access performance to the flash memory, and determines to compress data based on the selected one compression method and to write the compressed data to the storage area, and the first reversible compression method has a lower compression ratio and a slower compression speed than the second reversible compression method.

Storage apparatus and control method of storage apparatus

It is possible execute processing large-scale data and improve the processing efficiency while suppressing the complexity of a hardware circuit. A data processing device includes a processor and a FPGA connected to the processor. The processor is configured to acquire a query plan including target identification information identifying data to be processed and a processing detail for the data to be processed, generate, based on the query plan, a plurality of FPGA commands to process a plurality of row group data items constituting the data identified by the target identification information and to be processed, and transmit the FPGA commands to the FPGA. The FPGA is configured to execute processing on the row group data items based on the transmitted FPGA commands and return results of executing the processing to the processor.

Data processing device and data processing method

A system including a first storage drive and a superior device superior to the first storage drive, wherein the superior device specifies a first allowable environmental temperature that makes the remaining lifetime of the first storage drive longer than the remaining operation schedule period of the first storage drive, and controls an environmental temperature adjusting device that adjusts the environmental temperature of the first storage drive on the basis of the first allowable environmental temperature.

Control method of environmental temperature of storage drive

An oil and fat composition is provided which can reduce cooked odors without using an additive such as emulsifier. The oil and fat composition includes an oil and fat produced by oxidizing a fresh oil and fat so that a difference in anisidine value before and after the oxidation is 0.5 to 350, and an edible oil and fat. An added anisidine value of the oil and fat composition is 0.07 to 350 and is further calculated by the following formula: added anisidine value=(anisidine value after oxidation&#x2212;anisidine value before oxidation)&#xd7;[additive amount (wt. %)].

Oil and fat composition

A storage device relating to one aspect of the present invention has a storage controller and multiple memory devices. The memory devices manage capacity equivalent to the size of a memory space provided to the storage controller among regions of a non-volatile storage medium as logical capacity and manage the remaining regions as reserve capacity. When a device controller determines that a portion of the memory regions in the non-volatile storage medium is in an unusable state, the device controller notifies the storage controller of the size of the memory regions in the unusable state. On the basis of a policy set by the memory device, the storage controller determines the reduction amount of the logical capacity and the reserve capacity and notifies the memory device of the determined reduction amount of the logical capacity.
