Do you have access to the backend of the site or just the manegment console?

If you can get to the folder structure of the site I would jump on there using FTP if possible and download all of the folders immediately. That at least should give you the ability to cull through the data at your own pace instead of being under the gun.

I am not aware of a specific program to do what you are asking websites aren't really my thing discussion boards even less so. Still they are still setup in a standard folder structure and if you can access the server directly you should be able to copy all of the data.
