I would not bother much about having backlinks on Alexa as this works differently than Google Webmaster tool and Yahoo Site Explorer.
Additionally, the stats you see in Alexa is based from user visits to their site. Meaning if users do not search your site using Alexa, then your site won't be included there. Also, Alexa website stat is not regularly updated, usually the stat you see is based from 6 months review.
So if you are going to use Alexa to analyze backlinks, it would not really be that helpful at all. Stick to Google Webmaster tool or Yahoo Site Explorer instead as these tools provide you with concrete information on backlinks.
I hope that helps!
