I will agree with Erro ... I think you are making a terrible mistake by throwing away your Raws...
Most people leave the Raws in their Lightroom catalog, and only produce JPGs when needed, not as a regular step. The only time you need JPGs is to send to some outside application, like e-mail or web, and those don't get re-imported. [/quote]
One of the touted features of Lightroom is it's non-destructive processing ability with originals. You have managed to circumvent that. For all the benefit of Post processing, you might be as well off using Photoshop elements. As others have pointed out, It is not really necessary to produce a permanent JPEG when you can export a temporary JPEG anytime you need a dreivative. Sometimes it is important to have a pernanent copy of a derivative. From time to time I do this. On export I create a JPEG and on the Export panel in the "Export Location section, Not only do I specify a location, I also check the box "Add to This Catalog". Once I do that, Re-importing is unnecessary.
In light of all the comments, I hope that you will reexamine your workflow and your backup plan (or lack thereof.) And please let us know what you have gleaned from this topic discussion.
