摘要: An information processing apparatus includes, a first storage unit, a second storage unit in which data stored in the first storage unit is backed up, and a memory controller that controls data backup operation. The memory controller divides a transfer source storage area into portions, and provides two transfer destination areas, each of the two transfer destination areas being divided into portions, backs up data in a direction from a beginning address of each divided area of the transfer source storage area to an end address thereof in one of the transfer destination areas provided for each divided area of the transfer source storage area, and backs up data in a direction from the end address of each divided area of the transfer source storage area to the beginning address thereof in the other transfer destination storage area.

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.
