I have around 40 courses, and sometimes I get 2 unfinished and sometimes I get 5, and so on, it is never the same courses either, it varies. I was wondering if it was possible that it has trouble if there is a student in the course posting to the forum or something when it is trying to backup?
The backup log for that course usually has
copying user files
copying course files
as the last line for that day, if this helps any.

I am also having this problem.. using moodle 1.5.2+. Everything was fine and suddenly, eveynight, just one back up fails. It seems to be a different one ach night, so nothing to do with file permissions.Normally its just the shorter , more simple courses fortunately, with just a set of files in the listing. Manual backups work fine.
THis seemed to start happening when i upgraded to 1.5.1
I struggled with this problem for months while using lynx to call /admin/cron.php.
Once I switched to /usr/local/bin/php the problem went away!
