Let's see, some years back durning the eighty's depression while I was on
the road looking for work I left my negs and prints at my parents house
which burnt to the ground. I don't know those film negatives and prints just
don't seem archival enough for me.

Have more than one copy.  Keep the original in one place, perhaps off in
a safe deposit box, and make two or three backup copies, keeping one on
your hard disk, another on tape, and a third on a CD.  Keep them all in
different places.

Keep more than one copy, in more than one location, on more than one
medium.  Storage media have a life span, so plan to re-copy most of your
files when necessary, or when a new medium becomes dominant.

I was out taking photos this morning, and a chap started taking photos of
the same statue. I noted that he had two cameras, one of which was digital
and the other 35mm. Sometimes he took the same shot with both cameras and I
got nosey and asked him why.

He was very positive about digital, the quick access to prints, but had
lost (on very rare occasions) the digital images and took a back up on film
of a good composition.

Make of that what you will, but it did not put me off digital, or make me
happier with film. After all, there are many opportunities to ruin film
between shooting and development!

Not saying I have the best answer -- be interested in any better suggestions -- but 
all digital photographs I'm interested in preserving are archived on at least two 
separate CDs. In other words I have two sets of CDs on which I archive them, and then 
if they're part of a project they go into whatever folder is relevant to that project, 
on yet another CD (or two).

Burnable CD's do not have a long life span either. Assuming in 30 years
time you have something to read them they would probably not work!
I have some from jus tfive years ago and they are unreadable now and

And, IMHO one should also verify the data is properly recorded on the copies and
that the recovery process (software/hardware) works.

I see a half dozen or so major data/information losses each year where the backup
process is executed flawlessly -- or nearly so, but the data is lost due to
inadequate testing the recovery process.

How true but people put to much 'faith' in the damm things.
I work on SQL databases and had one customer (a big international firm)
that backed up to tape every night.
They even checked the log to make sure that it was ok.
It's a pity they didn't scroll down to see that the last set failed
every night for four months!!!
I got £2K for half a days work restoring the databases  they lost £20M a
day whilst they tried to work out why the backups would not restore!

 I heard a good story from an ex-Telecom guy here.  Apparently they'd 
upgraded the software on an exchange and everything appeared to be 
going normally for several months, until one day when the whole thing 
turned to custard (crashed).  It was so bad that they had to restore 
the system off their tape backups.  

What they didn't realise is that the software upgrade had a bug which 
was writing corrupt data to the tape.  They keep about 6 months worth 
of tapes and they were all stuffed as the upgrade had been done a 
long time beforehand.  All the data had to be re-entered by hand from 
written records.  

You can never be too paranoid about your backups...
