Yes it works with NFS. But it scales poorly

I am running a small installation. only 23 hosts.  on a 6TB nfs nas,
using mostly gigabit ethernet.
5.9T  3.4T  2.6T  57% /var/lib/backuppc

speed varies between 1 MB/sec and 8MB/sec with the average laying about
3MB/sec for a full backup. and  0.5MB/sec for incremental

cpu is often in iowait during backups.

mark: this is all server hardware intel server gigabit network cards.
and lsi sas raid controller with sata 500GB raid edition harddrives
