Calliope is my Roon Core, but Arrakis is a separate WIN10 PC.

To back up to a drive on another networked machine -

  1. Set on sharing of the folder on the machine where the drive is. Give necessary permissions.
  2. In Settings==>Backups==>View==>Add==>Browse==>Add Network Share
  3. Use the share name that resulted from Step #1.
  4. Don’t forget appropriate id/password

OneDrive is not supported.
