I am working in a freshly upgraded moodle, 2.9.1+. I have a pretty large course that I need to back up. When I I start the procedure everything works and then it seems to stall at the end--the process stalls at 99.66% complete, it appears to keep running (the blue bar is doing its sripy thing) but it stays that way and the backup does not complete (I have waited for at least an hour with it stuck at 99.66%). I read that there can be an issue with courses over 4 GB, but I don't think this course is anywhere near that large (how would I tell?). I had the same problem with backing up this course with moodle v2.5, but thought that upgrading (which I planned to do anyway) might solve the problem. It hasn't.
I'm stuck at this point, I don't know what to do to get this to work and I am under some time pressure with school starting, I would be very appreciative to hear of any suggestions fellow moodlers might have.
Thanks very much!
