Repeated Rekordbox Library Backup

I appreciate that rekordbox has the option to back up your library in the File menu.  But I will most likely forget to do that.  Is there a way to automate back ups? What I would really like is a scenario where everytime I close RekordBox (or at some time everynight) the back up occurs and the file gets saved to something like dropbox or google drive.

Is there someway to do this?
