Automatically backup race_out.json after every race

[blgk]

Hello,
Is there a way to automatically backup the file race_out.json after a race, before it's overwrited for the next race?
In multiplayer when the server starts a new race this file is overwrited and I want to keep it for summiting to simresults.net. I can do it manually but it's easy to forget o there isn't enough time.

Thanks
