OK, this questions isn't what you're thinking. I know that Time Machine will not work with and AirDisk as the backup drive. What I'm wanting to do is the opposite. I have an AirDisk connected to my AEBS that has my iPhoto and iTunes libraries on it so that they can be accessed from multiple computers. I've already got an offsite backup setup, but I want to back up the AirDisk to Time Machine also. That way if the drive goes bad it would be much quicker to restore than from an offsite source.

    What's the question? I don't see why this wouldn't work. I guess the question YOU have to answer is what disk you will use for your time machine backups.

    I found this information that seems to be helpful (can't vouch for it, because I'm only now planning on doing exactly what you are -- albeit with a time capsule for backup instead of a directly attached drive).



    It looks like Time Machine will exclude external disks by default. If you remove the external drive from the exclusion list, you should be all set:

    • Open Time Machine Preferences
    • Select Options...
    • If the external disk is listed under "Exclude these items from backups" then remove it from that list


    BTW, how is the performance if iPhoto with the airdisk? I tried it once and it wasn't usable, but that may have been an issue with the portable hard drive I was using. I've been holding off on getting a new time capsule in the hope that it will have USB 3.0 and eliminate the possibility of the USB being the performance bottleneck. Anyway, do you find performance acceptable with your library living on the airdisk?

    Salda, unfortunately my further research reveals no solution. The FAQ from the earlier link states that Time Capsule will not backup any network drive at all, INCLUDING the USB drive attached to the time capsule itself. This is a major bummer for me (as I'm sure it is for you as well). This is really a half-baked solution in my opinion. It means the USB drive is really only useful as extra backup space.
