How to backup saved changes to imported itunes tracks (cue points, beatgrid, etc.)

Hi all,

I'm new to rekordbox and couldn't find an answer via the search.

I imported my itunes tracks and playlists into rekordbox. All my itunes songs now appear under collection - everything works fine. I also did some adjustments / changes to all of the tracks manually in rekordbox (corrected beatgrids, set cue points, etc.) which took me quite some time.

My questions is: How can I save / backup all these adjustments (corrected beatgrids, set cue points, etc.) to let's say an external harddrive? I.e is there a "library" / folder / meta file etc of rekordbox that saves all these changes and relates / links them to the respective mp3 from itunes?

I need the backup in case I eg lose my laptop, so that I can easily restore my itunes (I did a backup of the itunes library and my mp3) AND ALSO all of the rekordbox changes / adjustments TO the respective tracks in itunes?

For the purpose of understanding: where does rekordbox save all this data? And how does rekordbox link the changes / adjustments I made to the mp3 / itunes tracks?

Thank you very much in advance and kind regards,

Alberto
