Try this;

save bserver -p FULL -l full /export/home/jeffd

Starts an explicit full backup of the "/export/home/jeffd"
directory to the backup server named "bserver" and causes
a volume from the "FULL" pool to be used. The "-s" option
is only relevant if there are multiple backup servers
available to this client.

I thought -b was switch for pool.... I'm quite sure you can't just type like that on NetWare.
