While the Internet Archive (IA) is a great service, it's not really meant for day-to-day use. It's an archive, not a production website. If you want to restore a site from the archived copy, that can be a lot of work, since IA changes all the links and adds a header. Archivarix acts like a reverse archiver - it extracts the site from IA, cleans it up, and presents it to you in a zip file ready for mounting on a web server where it can resume its former life as a real web site. It won't be perfect - things IA couldn't harvest, like CGI scripts and some background files, will not work. But in many cases, the results will be quite acceptable. Robin Good reviews the site and shows some videos of it in action.
