NFS is an networking system not part of virtualbox.
Virtualbox has an mechanism of its own to allow gests access to host
filesystem you shoulkd try that instead.

It's not an good idea to backup database file while firebird-server is
running on that file. You should use firebirds backup functionality instead.

This option is for pepole knowing what they are doing - those pepole
usually do not ask if it is ok.
