Solution: Time Machine over AFP
At work, I’ve been preparing everyone for an eventual update to Mac OS X “Leopard” (that’s Mac OS 10.5 for all you purists out there). I ended up ordering about $15,000 of hardware to get a backup solution going on for the whole office. This included: an Apple Xserve (running 10.4 Server), 2TB of storage, a cisco router, UPS, yada yada, good times, yada.
The idea was to have everyone connect to the Xserve, and use the new and advertised “ Time Machine” feature of Leopard to backup everyone’s data hourly over the network. But of course, come release day - Apple have made it so you cannot use a network share as a backup drive with Time Machine, unless the computer hosting that share is running Leopard Server (that’s 10.5 Server to you kids taking notes at home). So, after spending plenty of cash, I was being forced to upgrade to an un-proven, bright-eyed, un-tested server operating system to use one feature at the cost of $1200AUD.
Until now.
The solution: Open Terminal. Paste this in: defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
Now any network share will show up in Time Machine so you can backup to wherever you like without having to waste your time/money on upgrading first.
Apologies for funny formatting. I copied and pasted this from my blog.

From what I understood (thanks to Currawong's explanation on MTAU podcast 8 - coming soon!) this wasn't really possible as Tiger doesn't support the newer handling of hardlinks in Leopard that make TM work.
Have you tested this pretty thoroughly, e.g deleting and restoring whole directories? Does it work exactly as advertised?
If so, put a Digg link on this post
(edit: no of course you haven't tested it - you just wrote this up and posted it on the assumption that it will work  But I like to be reassured.)

Nah, no need for digg.
I have it working here on two computers. Seems fine, restores stuff...
What can i do to test it?

I vaguely recall Currawong saying something about hardlinks to directories not being possible under Tiger (feel free to correct me, Currawong ).
Could you maybe try deleting a folder with a file in it, then restoring both later? |

Tested it with a folder full of files. Moved to trash, emptied trash. Time machine restored it from a week ago.

Awesome
Definitely worth a digg though - I think many many people would like to know about this. I know you just saved me from having to buy a Quicksilver G4 to use as my TM server. |

If your HDD plugged into the AirPort Extreme is shared via AFP - yes. This hack allows any AFP share your computer can see to be used as Time Machine volume. |

I might have to test this myself. Can you restore a bunch of folders? It's hard-linked folders that were new in Leopard.

Just spoke to a developer who knows a bit more about Time Machine.
It seems that whilst the ability to write to AFP shares was in the developer releases of 10.5, it turned out to be unstable, so until an update is released (which is not far away) it was turned off as default.
Allegedly, Time Machine requires a hack to the way symlinks are written to allow hardlinks to be linked to non-local volumes, and the hack results in the loss of metadata.

Not within October, and there is no upgrade program for OS X server. (Yes, i thought the same thing).

Bugger. As it is, getting the CPU drop-in kits is harder now; Apple used to drop a heap off and we just insert them into the boxes. Now, they insert them into the boxes at the distributor, if they haven't been inserted in, it's a PITA to get them (having just organised a fair few of them for people that bought machines after the release date but before Apple got round to inserting the software into the boxes.)
