Automated Asynchronous backup - e-mail notification/summary

Hello,
Well Yes, my servers (all3) use php-fpm, versions are the same. I checked logs, no error logs for mail, actually no logs for that particular time during backup or right after backup.
Yes, my backups are set to mounted disk, the big one has 1TB, 2 backups are kept, skipping courses with no change and hidden courses. Those backups take 560 GB.
Exactly, my small site backup message looks like (sorry comes in Slovak), according to logs, it took about a minute:

>Look in /moodledata/temp/backup/

They are all zero. According to listing the first is modified 1:50, the last 13:31 the same day. So I checked mail.log for that time. There is notification sent about newer version at 13:07, which I have received.

 

And YES, I was checking the Scheduled tasks as well, and I did find it strange as well.

 

I was thinking of disabling asynchronous backup for weekend (as my course backups run on Sundays after midnight) and I'll see what happens. The jump from 4.1 to 4.5 did not affect my small site nor migrated small site. But Moodle 4.5 is asking to have them in Server>Environment check. That's why I have changed this setting.
