Hi Alain, it's around 80G counting all schemas. Mysqlserver is running on the same bare metal server as apache-php-fpm. We are running multiple moodle instances and sometimes few of them cause heavy loads on mysql service but only during backups.
However, even if we were running mysql on a separate server, off-loading backups to mysql server would only optimize gzip processing and file IO optimizations, which is definitely something, but still it won't spare mysql service completely.
In the mean time I've found this thread and all the possible gotchas if using master-slave replication so it seems it might not work as I have expected.
