Yesterday’s Time Machine/Airport update finally activated a feature that just about everyone has been waiting for. You can now attach a USB external hard drive to your Airport Extreme and back up your files wirelessely from any Mac on the network. Essentially, it makes your Airport Extreme and an external USB drive into your very own Time Capsule.
This feature is one that Apple began promoting long before the official release of Leopard. Prior to launch, however, the feature mysteriously disappeared, and we didn’t see or hear about it again until Apple launched the Time Capsule product. It’s good to see them add this back in as an option for current Airport Extreme owners.
