Along the lines of @Alecos Papadopoulos's answer, it is pretty easy to save webpages to your hard drive and view them offline, or if the site disappears. These are only a couple hundred KB. They can be viewed in a browser just as if they were live. Note that, if the site disappeared, the links to other CV pages, for example, would not work.
Another possibility, should you not have saved a page and the site disappears, is to go to the internet archive Wayback Machine. From there, you can enter the address of the page you are interested in and go to an archived version of it. Be aware that pages are only scanned every so often, so changes made between the last scan and when the site disappeared from the internet would not be recorded.
