Tim, the -W option allows the dump command to _write
to_ multiple volumes rather than _read from_ multiple
filesystems.  If I understand your question correctly,
trying to read data from multiple filesystems and
write the backup to a single tape/disk/etc., you would
simply list the files/directories to be backed up.

For example, if you have two filesystems:
/dev/hda3 mounted on /home
/dev/hda4 mounted on /opt
and you wanted to back them both up to a tape on
/dev/st0.  Assuming both filesystems are mounted, your
dump command would look something like:
dump -0u -f /dev/st0 /home /opt

HTH,
Brad.
