Yes. It would get rid of that 11GB. But I can't see how that particular information, which is of a temporary/transient nature, could cause anomalous behavior. And, given the size of it, I'm not entirely sure what the data in there actually is.

I'm certain that SuperDuper! has created a good backup (which you should update, given the amount of time in between the last backup and now). But I don't think that I'd erase my drive without a definitive goal in mind that I was sure I could accomplish by erasing it. (Example: repartitioning it, severe fragmentation, etc.)

Anyway, here's what I'd suggest. Update your backup. Then, send your SuperDuper!.log -- which you'll find off your Home folder in Library/Logs -- as an attachment to support -at- shirt-pocket.com. I'll take a look at it to make sure that you're ready to erase, if that's what you really want to do.
