[nonissue]

It actually makes sense. If you think about it, if every external that anyone ever plugged in was backed up and then never seen again, that could be sooo much data. What if that drive was used, wiped, renamed and then used again? You potentially have the same drive on BB twice.

A way to alleviate the issue would be to charge a small fee per drive or per account for persistent external back ups. If it was 1-2$ a month extra for the peace of mind that a drive would always be backed up, I'd gladly pay it.

At the end of the day, you have a choice as a consumer and you went with bitcasa. I'm happy paying $5/m for unlimited backup for my main computer. All said and done it's an amazing deal, even when you consider the external drive issue.
