This is a problem I have had for a long time. When I do a backup (as admin) mbz files turn up in the "user private backup area". When I click on the "Manage backup files" buttom I get the following error:
"Can not read file, either file does not exist or there are permission problems"
These "files" are contributing several GB to the size of our site. The problem has been there over many versions of Moodle and is still there after I upgraded to v2.6.1+
Can anyone help, please?
