Hi Stuart, thanks for your response
This image shows the Teacher's Restore page, you can see the backup files of the course "CursoApoyo"
And this image shows the backup files of the same course "CursoApoyo" but through the Administrator user.
The administrator can't see the file "respaldo-moodle2-course-3-cursoapoyo-20130412-1448-nu.mbz"
The Administrator must delete the files that are saved over a year, so we need that can see.
Thanks
