A few months ago, I purchased a Western Digital My Book Live to use solely for backup purposes. Since receiving it, it has worked great keeping my iMac backed up, and I even planned on switching Joy’s MacBook Pro to using it, too. Well, it doesn’t look like that switch will be happening soon.
After the release of OS X Lion earlier this week, it broke support for older NAS drives. Apparently, Lion requires that a NAS uses the latest version of AFP; specifically, the drive needs to support DHX2. Here is the error that you get:
Time Machine could not complete the backup
The network backup disk does not support the required AFP features.
Thankfully, after some searching at the Western Digital Forums, it looks like they are going to try and update the My Book Live firmware as soon as possible (looking like sometime in August):
We are working on a solution for My Book Live. As I stated earlier in this thread, we will likely not have it out before OSX Lion is released but we will have a solution. We have a firmware update coming out in the next few weeks, but it WILL NOT contain the Time Machine fix. It is likely that the firmware update for this will be sometime in August (depending on how fast we get it tested). We have verified that the released code works , but as I said, it is not tested (Yes we are talking to the Netatalk team).
If you own a My Book Live, sit tight and an update will hopefully be around soon.

[update]It looks like they have the issue fixed for My Book Live. Their latest support document for firmware version 02.01.06 – 026 shows that they’ve added in the fix. Their status page has also been updated:
A firmware update (02.01.06 – 026) for the My Book Live was released on August 2nd, 2011 that addressed this issue. You can download this update either using the automatic update function of your My Book Live, or by following the manual update instructions in Answer ID 5735: How to update the firmware on a My Book Live.
A firmware update is in development for the the My Book World (White Light), the My Book World II (White Light), and the WD ShareSpace to update the version of Netatalk (to 2.2). At the current time, there is no workaround available for these drives.
