When a Jail needs to access a NFS mounted device I use to mount it on 
the hosting machine (the system outsite the jail where jail is runned 
from) in any mount-point, so I mount_nullfs inside the selected jails, 
say, mount_nullfs /nfs/backup/200.200.100.40 
/usr/jail/200.200.100.40/mnt/nfs/backup;

The problem is that you cant do it if you are not the jails admin (ie, 
you dont have full access to the jails hosting system).
