When we try and do a backup of a course, we get this error:
PCLZIP_ERR_MISSING_FILE (-4) : File '/moodledata/temp/backup/1164825320/course_files' does not exists
When I look in the moodledata folder, everything is there, but it doesn't create the zip file, which essentially makes it useless. Attached is a screenshot of the error. I don't think it's a file size thing, the course_files folder is 6.24MB, but we have a 8MB upload limit, but that shouldn't matter in this case.
Any ideas? thanks!
