A method to back up your website is to PDF the entire site. We use Adobe Acrobat 9.0 professional since we are not aware of an open source alternative that automatically indexes the pages in the PDF. Please leave a comment if you know of an open source program that PDFs an entire website.
We download websites in PDFs to give a backup to our clients who can easily review and proofread the site. Below you see a screen shot of a PDF we made earlier of this site. You can also install a copy of a production site on your client's computer using this tutorial.
