I am attempting to download a backup (mbz) from our Moodle 2.1.1+ server to use on another server. I can do just about anything with the backup EXCEPT download it. I can rename it, move it to my private files area, completely restore a new course on the existing server with it. When I attempt to download it, I get a "File not found: Firefox can't find the file at http://moodle.ourserver.org/pluginfile.php/100/user/backup/Backup2CourseName.mbz?forcedownload=1." I have other backups on the server that I am able to download. I'm not sure if it has an impact, this course is fairly large (for our server) at 320 MB, but I believe all the settings are set at 2GB so that shouldn't be an issue.
Does anyone have any suggestions for why this is occuring? And, better yet, a solution for getting the download?
