Although I’ve used Duover for backups until now, I’ve decided to stop using it for two reasons. The first is that it seems to be floundering with the release of Leopard, making backups incredibly slowly, and generally flaking out. As an example, a daily backup from my kitchen machine took about 20 minutes under Tiger but, even with the latest Duover update, was taking over four days under Leopard. Not at all useful. Secondly, Time Machine is just really useful and cool.

So, I’ve just installed a 1TB Time Capsule backup device into my home network. It’s been a real breeze to setup, even for an Apple product. Simply just works. Even though I was pretty sure it would do what I wanted it to, I had a nagging suspicion that my network setup might trip it up, but this turned out to be groundless. My home uses two different wireless networks, one using 802.11g, to serve the older machines, and one using 802.11n to serve the newer machines at the best speed. (Hardware that runs 802.11n can also support 802.11g simultaneously, but doing so really slows down the 802.11n portion.) The additional speed on the 802.11n network makes a huge difference when streaming HD video to the Apple TV (though the g network can handle DVD level video just fine). My setup works basically like this:

I wasn’t 100% sure the kitchen machine (“Nexus”) would be able to see the backup service, but it works fine, just as a good network service should. As long as the machine and the device are on the same LAN, it appears to make no difference how it actually gets there, just as you’d expect. (That initial backup sure is slow, though.)
