Automatic Library Backup

Hello dear Rekordbox team. This is a feature request. It would be great to be able to backup my rekordbox library every time I exit rekordbox app. I tend to forget to do it by myself though the upper screen menu. 

I save my library backup files to my icloud drive. If I could tick that auto backup feature on and set that folder for my backups, I would not have to worry about latest changes not being saved if something happens to my computer. I know it sorta circumvents the necessity to pay for subscription and use your cloud backups. I thought I'd at least ask :P
