Quite frankly x12 isn't supported in the UK so we don't know the software - so I can't be 100% certain my soln would be apt.
1. Stop the backup, check the musicBD for errors & also check the backup drive is well formatted.
2. Perhaps you could do a manual dump over a network ?

I've tried but my Mac doesn't recognise the Linux HDD in Disk utility application. When I connect via a cable network connection, a manual dump is blocked to copy to SSD although I could select all songs.
As I mentioned my database is a mix from Flac files, HigRes and a few Mp3s, but does Cocktail audio or Novafidelity accept a mixed Database for backup?
