Did that solve your performance problem? It'll increase the time for the automated backup process to finish.

Hi Andrej,

What's the number of this task parameter on your server: "task_adhoc_concurrency_limit"? This means the number of adhoc tasks that run concurrent when the automated backup task is running. You could try to tweak this number.

Andrej, what's the size of your MySQL database and have you loaded your database in-memory (InnoDB)? I understood you already did the tuning for better performance. A slave replication could be a solution, with a Moodle instance (without Apache) on that server. I believe I described in the link https://moodle.org/mod/forum/discuss.php?d=385643 how to configure this instance. Running the automated backup directly on the DB / data server was our solution for running the batch in a cron job during the night. Next morning all our backups (about 300/400 backups each night) were ready. Where resides your moodledata, on the same server as Apache and MySQL?

Ken, that's already some time ago I used this solution for our backup problems. I'm testing now with Moodle 4.0 beta version and the automated backup task gives me a headache again. I explained it in a post in this group here https://moodle.org/mod/forum/discuss.php?d=429167

Hi Andrej,

Which Moodle version are you running and is the stack running on one server (application + database)?
