Abstract
A control device manages a plurality of storage devices so that data to be recorded is redundantly recorded in different storage devices. An error monitoring unit monitors an occurrence of an error in each of the plurality of storage devices to register information indicative of error occurrence conditions in an error information storage unit for each storage device. When the use of one of the plurality of storage devices is stopped, a rebuild controller determines a timing to perform rebuild processing based on past error occurrence conditions in the storage devices other than the one storage device of the plurality of storage devices by referring to information registered in the error information storage unit.
