I almost do the same thing that Charles does.

I save everything that I shoot, RAW, JPG and converted pictures that are uploaded.

If the picture totally didn't come out is the only time that I toss it. The others I can learn from.

I do copy to DVD-R

Not archive material but I use good quality DVDs, Verbatim or genuine Taiyo Yuden.

You can catch them on sale for $15-$20 for 100 spindle.

So in total I have 3 sets of pictures on my computer, external HD and DVD.
