Does anybody know how much space roughly (Snow Leopard)?

Probably under ten gigs, but it depends on what'all you've installed. You can find out how much is on YOUR particular Mac by using this command from Terminal, in an admin account.

sudo du -hcd 1 /


Please note that few of us recommend leaving system files or even your applications out of a backup. Sometimes you install products that modify the system. An incomplete backup can mean a lot of pain when it comes time to rebuild.

The article specifically recommends leaving out apps. Uh huh. Do you know where ALL the original media for your apps are? Is it stored somewhere such that the catastrophe (fire, etc) that damages your computer won't get them too?

This is why we recommend multiple backups, at least one being a *complete* *bootable* clone using Carbon Copy Cloner. If your internal HD fails, just boot on the clone!
