I think I discovered a bug with file backups. Changed my sites backup frequency to "Each night" and now find it not running each night.
Also the table overview of setup backups does show a few days between "last backup" and "next backup".
Something seems to be not updating accordingly. Tried to run these backups manually to make it update the interval but with no effect (to the table at least).
Also I'm confused that "each night" seems to be 15:00 o clock in the afternoon. Maybe that's a timezone issue? (I'm in Europe/Berlin)
Thank you
