Abstract: An information processing device includes a processor that performs a process. The process includes: when the information stored in the first storage unit is stored in the second storage unit, storing the storing completion information corresponding to the stored information in the storing completion information storing unit; detecting a failure in the information processing device; performing a restart process on the information processing device using a region in which the stored information has been stored in the first storage unit on the basis of the storing completion information when the failure is detected; and discriminating information that has not been stored in the second storage unit from among the pieces of information stored in the first storage unit on the basis of the storing completion information when the failure is detected, and storing the discriminated information in the second storage unit.
