possible to use internal hard drive on desktop as laptop time machine?

[gnychis]

I have a 2TB internal hard drive on my Lion Desktop. I have a Macbook Air, which I would like to use that 2TB internal drive on my desktop for time machine. Is this at all possible?

According to Apple, it is possible with 10.6 (Snow Leopard):

Don't know about Lion - though I'd guess it should probably work as well.

thanks a bunch! that was really easy. Just turned on File Sharing on my desktop, then added my Time Machine disk to the list of shared things. On my Laptop, I authenticated with my Desktop, and then just added the disk in Time Machine!
