if normal backup is not a realistic option then yes, RAID is the way
to go, in your case, I'd suggest RAID5.

with RAID5, yes. its a relatively slow process but it works.

or x264, which is gaining in popularity amongst those with the CPU
power to decode it. For DVD conversions this isn't all that much
horsepower in all honesty and the quality difference is outstanding,
you'll basically get minimal quality loss at a great reduction in

Sadly, the best software for the conversions is for windows (mplayer
can do it, but from what I understand, is not all that ideal for it),
the good news side of that is from what I can tell, the software will
all operate under WINE.
