Abstract
Even if failure, or the like, occurs during the encryption process, the encryption process is surely resumed. A flag changing unit changes an encryption flag of one disk to being encrypted after an encryption request is received and before the encryption of the data stored on the one disk is started. The flag changing unit changes the encryption flag of the one disk to having been encrypted and changes the encryption flag of the other disk to being encrypted before copying the encrypted data from the one disk to the other disk is started. The flag changing unit changes the encryption flag of the other disk to having been encrypted after copying to the other disk is completed.
