the s option is ancient.  See the dump(8) man page and use the B and b
options to specify the # of blocks and the blocksize.  Other than rst0
will rewind the tape when done, your dump command looks sane.  

For a Connor 2GB SCSI tape we have, we use the following:

rdump 0uBbf 2000000 10 resnet2.uoregon.edu:/dev/nrst0 /
rdump 0uBbf 2000000 10 resnet2.uoregon.edu:/dev/nrst0 /var
rdump 0uBbf 2000000 10 resnet2.uoregon.edu:/dev/nrst0 /usr
rdump 0uBbf 2000000 10 resnet2.uoregon.edu:/dev/rst0 /usr1

(we're using rdump but just change the rdump to dump and the host:path to
just path and you should be good.  Unless your /home changes a lot you
don't have to unmount it.)
