I'm in the same boat as Xian.  I want to backup to DVD so I can upgrade to 
5.3.  dump in 4.10 does not have a -P option, and growisofs says nothing about 
handling spanning, so how do I span my dump over multiple DVDs?

dump -h0 -B 4589840 -S /usr says I'm going to need 6.18 "tapes".  I'm going to 
crack open a beer and just pipe it, to see what happens.

Then some day if all goes well I will split /usr into /usr and /usr/home, 
'cause this is ridiculous.

Thanks.
