Around lunch time the site was up and working again and i remembered to do my housekeeping. Sadly i pressed the wrong button and instead of "Delete backup" i pressed "Restore" which started the restore of the old backup (16th of november). I recognized it fast but anyway too late

The biggest problem is that the restore wont complete because this forum is too big. So it was in an inconsistent state. I had some real trouble to apply the current backup. I needed to split the posts table and import it step by step. This took me hours. But now everything should work again. Sadly all posts between 06:00h am (GMT/UTC) are gone.
Sorry again but sometimes you just click the wrong button...
