Backing up RYTM for repairs

I’m sending my RYTM MKI in for repairs and want to make sure I’ve backed up everything necessary.

I used Transfer for the first time.
1st I exported all my sample folders.
2nd, I saved all my patters within each project, then saved the project, and then exported the “Whole Project” using Transfer.

Should I also export all my “Kits” that I use per project?
Should I export all my sounds?
Should I export my pattern individually?
Or will saving the Whole Projects ensure that all of these things are saved and backed up?

Any advice or tips would be greatly appreciated.
I’ve been using this RYTM since it was released and never backed up anything except Whole Projects.
I want to be sure I have everything backed up in case they need to wipe the machine clean.
