Back up and .... Re: HDTV tuner cards

[Andrew W. Gaunt]

Our backup needs are fairly well understood (ie. we have one or
more answers for the questions listed below etc.). What I'm looking
for are possible real world "linux" backup solutions that folks on
this list may have actually implemented based on thier own
specific needs; which may be somewhatdifferent from mine, but,
that's OK. I can interpolate.
