Well, I suppose you could dump to a file and then rsync it to the
other machine...
Basically, I think dump would give you a file over there that
is in dump format and rsync would give you something that
essentially duplicates the file system you are backing up rather
than creating a dump file.
A dump file would be easier to pull back and restore if you had a
major/catastrophic loss of disk and had to replace the disk (or undo
an inappropriate rm -rf *).
Either would be about the same effort restoring a single or handful
of files from backup.
