I've upgraded our Moodle to the latest 1.9.9 stable release and switched debugging on. Just tried to back the course up again and it stalls with the following:
-
- line 2407 of backup/backuplib.php: call to debugging()
- line 427 of backup/backuplib.php: call to backup_encode_absolute_links()
- line 1117 of backup/backuplib.php: call to full_tag()
- line 3052 of backup/backuplib.php: call to backup_course_sections()
- line 60 of backup/backup_execute.html: call to backup_execute()
- line 135 of backup/backup.php: call to include_once()
. . . . . . . . . . . . . . . . . . . .
. . . . . . . . . . . . . . . . . . . .
. . . . . I think it might simply be too much for the server to handle. Any suggestions in this regard? Do I need to up any php settings or tweak something else?
The reason for backing up the course is that I want to split the students who use it - half of the students have now left so I have no need to keep their data (other than a backup) whereas the other half have one year left on their course. There are a significant number of students enrolled, but not a huge number - around 500. Each student has probably uploaded around 10mb of resources.
I did think it was a matter of file size, but when I exclude all user data, i.e. just backup the course files and details - it still fails with:
-

The beloved 'continue' button never appears at the bottom
