Avoiding duplicate files, backing up Engine Prime settings

Hey team, So I am not the most technologically sound person but trying to iron out a few issues. 1 - I have backed up tracks to external hard drives but seem to have lost a lot of settings, track ratings and comments as a result. 2 - I also seem to have duplicate/triplicate tracks on engine prime so would love any tips on avoiding that 3 - How can I back up my settings, comments, ratings etc? I have an average computer and have spent a long time categorizing my tracks. Is there a way to keep all of that information so that if my computer dies I don’t lose all of that information when moving to another device?? Thanks in advance
