Indeed. And rsyncing vtapes doesn't help much, since the vtapes' contents
differ a lot (it would be nice if at least successive level 0's of unchanged
file systems were (almost) identical. Anyone played with gzip --rsyncable
yet?).

So you will end up copying (at least) the full amount of data once per
dumpcycle.

I guess e.g. rdiff-backup would be a better solution.

If you just add data (e.g. your digital picture collection), plain rsync can
already be quite handy. Having broadband at home (6 Mbps downstream, 512
kbps[*] upstream in my case :-) is sufficient for these purposes.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
