Ain't that the truth.

OK,
what I didn;'t mention, the machines to be backed up are being used to do
seismic/geoscientific processing
(those who are really curious could take a peak at http://www.jasongeo.com
to see the cutting edge in seismic inversion, stochastic inversion
all in a marketing friendly format ;) [1] )
Which means that there might be more than 100G of data geenrated in a day
(seismic data these days is huge. We recently received a set of 9 DLT4
tapes to be loaded on our system. Amanda is still trying to recover ;) )
And you cannot hardware compress seismic data, even gzip doesn't get much
better than 95% ..

Now that's pretty neat ..
What would be really neat (bordering on total perfection) is if you could
have a single disklist, and have it shared over multiple tapedrives.
But I guess you're gonna tell me that that will be in 2.4.2p3 ;)
