I'm not sure about websites, though logically, I would guess that copying and pasting all the HTML (or whatever code it's written in, I'm no expert) into a Wordpad or notepad document would be a good way to save it all. This, given that you have access to the website's code in the first place.
If you're talking about forums, if you've got admin priviliges, most BBSs come with some method of backing up your forums so you can easily restore them when necessary.
