Don's MAC powerbook backup brew is combination of several tools and may be ever changing as well. I believe at the time we recorded that episode, he was using the free bitorrent sync for that. It could have changed by now. I know for backup he was using, I believe still is using too, the Time Capsule in MAC.
Don is constantly trying new software to get him the solution that he desires. So the sync that he used then may have already changed multiple times.
