As a reader pointed out, there is an easy way to enable Time Machine on non-supported drives.
The trick is to execute the command: “defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1″ in a terminal.
Before executing:

After executing:

As you can see, you can now select a network drive to use as Time Machine backup. The “alouca” drive is a samba mount, on a Linux box.
If you select a network drive, Time machine creates a sparse image on that drive, mounts it, and it begins to backup there. Quite smart eh?

It really pisses me off that they constantly disable features or you don’t know they exist until someone tells you and you have to go to the shell and type in some stuff.
How convenient is that?
Thanks a lot for the post, though.

Yea I’ll agree with you.
The thing is that the functionality is there, working great, but they disable it until they release “some great product”, in this particular case, time capsule, and they force you to pay for something like that.
Even if they have some great products, this behavior pisses me off!

Maybe, just maybe in their testing they realized that given the number of possible network configurations possible, they couldn’t guarantee a product that “just worked?” Instead they make it easy for advanced users to turn it on without getting the “I tried that and it sucked” word of mouth not to mention support calls.
Just a thought.
Thanks for this post too!

Needing an online Time Machine Backup, I created one out of spare parts and a 500 GB drive, using Ubuntu and Netatalk/AFP. So far, it works great. I documented it at http://www.myhovercraftisfullofeels.com/creating-an-online-time-machine-backup/
Hope it helps people!

Hi,
This is great! But I needed to reuse my existing backups. Found the solution here:
