1. A data processing apparatus configured to back up data in an external memory unit, comprising:
- an access control unit configured to set an accessible state of the external memory unit;
a setting unit configured to set the external memory unit as a backup destination; and
a backup unit configured to backup data in the external memory unit set in the accessible state and as the backup destination,wherein the access control unit is configured to not cancel the accessible state of the external memory unit set as the backup destination even when the accessible state of the external memory unit is instructed to be canceled and data is not being stored in the external memory unit.

Abstract
When an accessible state of an external memory unit is instructed to be canceled and data is not storing in the external memory unit, a data processing apparatus cancels the accessible state of the external memory unit if the external memory unit is not set as a backup destination, and does not cancel the accessible state of the external memory unit if the external memory unit is set as the backup destination.
