Hi,
I'm having the same problem with a Moodle course, which is above 2 GB and which has a lot of mp3 files (more than 30) in one folder. The backup procedure shows following error:
"Coding error detected, it must be fixed by a programmer: progress() value out of range" and stops.
I'm using Moodle 2.8.3 and PHP 5.6.
Unfortunately, until know I havent' found any solution for this error.
