I have a custom profile. I want that profile users to able to export data using "Data Export" link under setup menu. But that link is not visible to that user. How can I make that link visible to my user.
The help says that the profile needs the 'Data Export' permission, but unfortunately there isn't a permission with that name. There is, however, a 'Weekly Data Export' permission - if you enable that permission for the custom profile, that will allow access to the Data Export setup option.
One point to note, from the help:
