Thanks, but splitting the archive is not the problem (I won't keep the
archive anyway, it's just on-the-fly piped through the network to the
destination machine). I'm having problems with the tar taking too much
memory (to keep track of the hardlinks, I suppose). A way to invoke tar
multiple times _and_ keeping hardlinks across archives would be
preferred, but this doesn't seem possible - hardlinks need to be within
the same archive...

Thansk,

Tino.
