NFS mount FROM Volumio TO a server?

I am planning on having a local USB SSD disk on my Raspberry Pi for my music library, and would like to NFS mount that from Volumio to a PC. The intention is for the PC to be able to backup music from the Pi, or move music to the Pi.
I suspect Volumio lacks some packages to allow this, and I dont want to break it by trying to install extras… - does anyone have any experience of doing this?
