By default you can set the backup Hours, for all servers based on the time of the control panel server, this is ok if you are focused in one Continent, but its impossible to make sure automatic backups run only OFF hours, as an example between 12 AM to 6 AM for all servers, apart the ones who are on the same timezone as the control server.
I suggest we add the option to adjust backup hours on the server level to either use specific time or follow the defaults set on the control panel
