Re: 2.5.1 Automated backup skips a lot of courses

I've checked error log:
[Sun Feb 02 07:00:28 2014] [error] [client xxx.xxx.xxx.xxx] backup_auto_failed_on_course GMF0101-\xc5\xa0VIT

.....

On Moodle Docs I've read that Moodle database user should have permission CREATE TEMPORARY TABLES.

Database user has all privileges expect Grant. It has permission to "CREATE TEMPORARY TABLES".

How to fix this problem?

Thanks.
