    摘要: In a control apparatus, a write control unit controls operation of writing data to a non-volatile storage unit. The write control unit is configurable with given control data. A control data storage unit stores first control data for the write control unit. An input reception unit receives second control data for the write control unit. A configuration unit configures the write control unit with the first control data stored in the control data storage unit when the first control data has a newer version number than that of the second control data received by the input reception unit, and with the second control data when the second control data has a newer version number than that of the first control data.

    摘要: A backup method makes a backup of cache data to a nonvolatile memory by using a controller, the cache data being stored in the volatile memory. The backup method includes writing the cache data stored in the volatility memory in a selected area of the nonvolatile memory, generating party data by operating the parity operations between each of the predetermined parts of the cache data in the volatile memory, verifying whether an error found in the part of the cache data in the nonvolatile memory can be recovered by using the parity data, and rewriting the part of the cache data when the error found in the part of the cache data in the nonvolatile memory cannot be recovered by using the parity data in an area of the nonvolatile memory different from the selected area.
