John - As you know hard drives typically have a much shorter life than CD's
and eventually fail and take their data with them. The scary part is that
the failure time is unpredictable. Sometimes the data on the failed drive
can be recovered but usually at a very high cost.
If you did your back-up on two drives so each drive has duplicate info you
would probably be very safe. The likelihood of both drives failing before a
new redundant drive is put in place is unlikely. BUT you could lose the
drives and your entire system to a voltage surge. And then, with out other
back-ups you would be SOL.
As you say, the number of cd's can become large. I presently have 49 BU
CD's for sound and 10 for photographs.
I doubt that I will ever accumulate more than 200 BU CD's of sound
recordings which for me would be very manageable.
Eventually I may go to DVD or what ever David thinks is best.
