  • Patent number: 12140894
    Abstract: The history record unit, in the non-volatile storage device, records recovery history information showing a history of the recovery process. The suspension control unit, when the recovery process' frequency specified based on the recovery history information exceeds a first reference frequency, restricts execution of the specific suspension process which is in response to a satisfaction of the suspension condition. Further, the suspension control unit, when the recovery process' frequency specified based on the recovery history information is lower than a second reference frequency, which is lower than the first reference frequency, under a situation where the specific suspension process' execution is restricted, cancels the restricting of the specific suspension process' execution.
