"Right now the setting for Automated backup storage is set to "Course backup area and specified directory" ... "does this mean that there are two backups made for the same course?"
Don't mean to be a smarta-- but what do you think?
2nd question ... no ... changing destination options will not automagically remove auto backups that are in moodledata/filedir/
For that ... query of DB to find contenthash value of .mbz files in filedir.
Contenthash value is location in moodledata/filedir/
Manually remove file and then row in mdl_files that refer to those.
For how to do that ... time for you to 'grow' and dig and learn ... all by yourself ... other wise, where do I send the bill for consultation? ;)
