or restoration.
The password for the backup/restoration and the password on the controller side are used for the authentication.

Inputting the password on the controller side is not required at the backup or restoration after the first backup (setting of the
password for the backup/restoration). (The authentication of the password on the controller side is conducted automatically.)
Therefore, users have the following merits on the security.
