What do you do with the Negatives

What do you do with your original images that you have post processed.
do you keep them? do you even keep the original raws?
At the moment I:
- Import all images into Lightroom, quickly go through and
delete any blurry, over exposed, under exposed photos.
- Copy the RAWs to my PC and store there until i have 4.7GB worth of RAWs and burn them all.
If i make any changes to a JPEG i will keep a copy of the original JPEG if i decide i dont like it or someone asks for the unprocessed original.
Cheers
