There are some various attempts, the problem is reliability - not that they're always up, but how do you trust them? If archive.org shows a page at a date, you presume it is true and correct. If I provide a PDF of a site at a date, you have no reason to believe I didn't modify the content before PDFing it.
Yes, Wayback machine/archive.org is one of the best websites on the whole world wide web.

It's that important.
Agreed and that's why there's an incentive to DDoS it and degrade the quality. Are there any p2p backup solutions?
