Scheduled backups aren't made

Is that a manual cron on the plugin cron?

Assuming it’s plugin cron…

1) Delete the upgrade folder contents – They should be deleting when the script starts AND finishes, but if it’s accidentally too big, your server could stop.

2) Turn on the log and run an ASAP migration. That schecudules it for 60 seconds out, which should reproduce the error.

3) What’s the timezone setting on the server and what did you put in WP core?

4) Is anyone hitting your site in/around 23:57?

Sory for the late reply:

1. Just did that, and now it is again clean.

4. Not likely – this specific site is a work in progres so probably

So the ‘run now’ worked?

Item #4 may be why it fails. If no one hits the site, the cron job may get ‘missed’

Hello!

I’m terribly sorry for this late reply.

Just to confirm – I think that you are right – the site is offline for users and opened only for my IP. When I do not log into it for a few days there are no backups – when I log in the backup is made a few minutes after the logging in.

Yeah, sadly thats wp-cron in action :/ No traffic, nothing scheduled happens.
