I have an external hard drive attached to my Airport Extreme wireless router. I manage my entire MP3 library on that drive. I want Pogoplug to act as the backup to that MP3 library. I've tried to set this up via pogoplug sync, but no luck.

I assume the problem is that the drive attached to the AE, not my laptop itself. In other words, is it the wireless protocol that is preventing me from backing up the AE attached drive?

This seems like a simple capability for Pogoplug to accomplish. Any suggestions?
