Notebook user without admin-permission - can he use Retrospect? Which problems will occur?

[Myself]

On my notebook I have created 3 users: "Admin", "Guest" and "Myself" (without Admin-permission). How can "Myself" use Retrospect? Only for duplicating own files or for duplicating the whole hard disc (without the need to change the permissions each time) to an extern hard disc?

Retrospect requires administrator rights. You can try to configure the admin login under Configure>Preferences>Security
