N4 and N4 Player files share resources between the plug-in files (VST, AAX, and AU) and the repository folder.

After first installation using Aquarius application, when framework and system files are installed, plug-in files and repository folder behave as individual files, and for this reason, moving plug-ins files and shared resources repository folder manually to a secure (external) medium will be enough for make a correct backup.
