OS X Lion was released yesterday and I was super excited to upgrade for all the new features like Launchpad, Mission Control and full-screen apps. Once installed, it’s definitely been worth the $30 to upgrade. Except for one little problem! After about an hour, I got a message from Time Machine telling me the backup failed to complete.
I took a look at the message and this was the error:
The network backup disk does not support the required AFP feature.
Whoops! Not only that, I had my entire iTunes library stored on my NAS and all of a sudden it was not connecting to the media folder on the NAS either! Not good!
Well, apparently, Apple is requiring that all devices have to support the new Netatalk 2.2 protocol instead of any older versions. Netatalk is an open source AFP file server that supports the Appletalk protocol. It allows your Mac to connect and use a NAS for Time Machine backups, etc.
Unfortunately, most NAS devices on the market today that support Macs are running the older version of Netatalk. This means that once you install Lion, you will not be able to use your NAS for Time Machine backups or in iTunes as an alternate location for your media library.
So is there any kind of workaround? Nope, unfortunately not. You basically have to wait until your vendor releases an updated version of the OS for your NAS. Luckily, the one I have from Synology, has an update coming soon specifically for fixing this issue with Lion.
Below are links to some of the news or forum discussions about this problem for various NAS manufacturers such as Synology, QNAP, etc.
