I have a 1.5Mbps connection. Files seems to be about 3.1 Gigs each on 4 different machines . I have a freebsd box with extra 12 Gigs of space that I can save to. I would like to save to a cd writer on the same machine it is a Liton CDRW but that other task getting it running to copy. I think if I had a choice I would have my installation on a cd for the ports and freebsd I need. Then save the data only.
