I believe that you need to tell dump the mount point of the file system in
order for it to create a snapshot, rather than the device file for the
partition. (ie. snapshotting only makes sense on a mounted read-write
filesystem).
Also, if you're dumping a snapshotted FS to a local file, then bump up the
cachesize to improve performance a lot. Add '-C 32' to your command-line.

dump. Add '-h 0' to the dump command line to make that happen.
Cheers,
Matthew
