1. An auxiliary storage device for protecting a file system in the auxiliary storage device comprising:
a host interface configured to communicate with a host computer;
a data storage device configured to store data;
a user input device configured to receive information for selecting an operation mode of the auxiliary storage device and related information from a user;
an object database (DB) configured to indicate file system objects to be protected and protection types of the file system objects; and
a control device configured to;
when a command is received from the user input device, control the operation mode of the auxiliary storage device and manage the protection types of the file system objects in the object DB, and
when a command is received through the host interface from the host computer, protect the file system objects based on the protection types of the file system objects identified in the object DB,
wherein the operation mode comprises a normal mode in which a protection operation is performed in a case where an access target is a file system object to be protected when the host computer accesses the auxiliary storage device through the host interface, and a management mode in which a user designates the file system objects and the protection types through the user input device.
