Most of the time, backup filenames are like this : backup-moodle2-course-coursename-date-hour.mbz
But sometimes, I've seen there's something more at the end of the filename, ending with -nu.mbz or -an.mbz
Could someone explain what it means exactly, and if there are other extensions like these...
I suspect -nu stand for "no user", but i'm not sure. And -an could be for "Anonymized names" ?
