Yup--exactly. GNU tar in particular has progressed hugely since 1991.
In this case I wholeheartedly disagree with the author of the FreeBSD
documentation referenced above. Like anything else, you just *can't*
globally say "X is best--period". Different situations require different
things. While I *do* generally prefer dump/restore over GNU tar (and
cpio, afio, etc.), if circumstances are such that I am required to restore
a particular filesystem from a FreeBSD box onto an HP-UX box, for example,
then if that backup was made using FreeBSD dump I'm in big trouble. In
this particular case, GNU tar beats dump/restore hands down. If you need
portability, then everything else takes a back seat to GNU tar.
I'll admit, the above case would be pretty obscure, but the basis for that
section of FreeBSD documentation is so dated it's just plain ridiculous.
