How To Use Time Machine
You do need to know that Apple may not support this: Here's the official word: http://support.apple.com/kb/HT1733 (Leopard) or http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html (Snow Leopard).
You may be able to get it to work successfully, but there's no guarantee it will work well, or in the future.
From a post in another forum (found by V.K.):
That post obviously applies to Leopard; Snow Leopard appears to have added some requirements, that are also not supported by all NAS devices: some that were working with Leopard no longer work with Snow Leopard.
As long as you understand the risks, it's your call. But do yourself a favor and maintain some sort of secondary backup, such as a 'clone' via CarbonCopyCloner or SuperDuper, or some other backup app. (Many of us do that with any backup app: no app is perfect, and all hardware fails, sooner or later.)

From a post in another forum (found by V.K.):
The technical reason why Apple limits Time Machine to 10.5 AFP volumes appears to be to prevent disk image corruption. There were additional features added to AFP in 10.5 to support Time Machine. These presumably allow the disk image engine to force disk image journal data to write out all the way to the disk. Without such features, a network interruption can result in a corrupted filesystem on the disk image despite journaling. Remember, journaling relies on the journal being written all the way to disk before the changes take place. If you can't guarantee that (e.g., because of network/NAS buffering) then the journal is useless. Time Machine appears to rely heavily on disk journaling to deal with network drop-outs, interrupted backups, and the like. Take this away and your data is at risk.
If the NAS you are using supports these features it should report them to the OS and you should natively be able to choose that volume. If you have to trick the OS to use the volume it means the NAS does not support it.
To summarize: if you care about your backup data you should avoid using non-natively supported AFP servers.

Select Back Up Now from the Time Machine drop-down in your menu bar, and if the setup went as planned, your machine should successfully make its first Time Machine backup over your network and to.

Time Machine is a generally quick and convenient way to back up your data and has come a long way in terms of reliability since its inception in 2007.

Set Up Time Machine With Time Capsule
- Check ‘Share as a Time Machine backup destination'. Enter a limit if you want, this will be a total limit for all the Satellite Macs that you will be connecting. Step 4: Set up Time Machine on the Satellite Macs. Open System Preferences - Time Machine; Click on ‘Select Disk' and you should see the folder you shared in Step 3.
- To set up Time Machine, plug in your secondary hard drive. When your Mac asks whether you want to use it for a Time Machine backup, click the Use as Backup Disk button. This step is really all you need to do, unless you want to customize which files are backed up. The Mac begins dutifully copying everything on the computer, including system files.
