Very true.
Also, dump/restore allows you to use snapshots on a live filesystem (I would
test it properly on a large FS with heavy activity). 

Now, if you are worried about "backing up the whole filesystem"...well, just
tell dump not to dump it :)

man chflags (in particular, the nodump flag)
man dump (in particular, -h )

having said that, each tool has its advantages.... i use rdiff-backup for my
laptop, but dump/restore on servers .
