Google runs fairly uninhibited for the most part, largely because of the aura of usefulness they seem to have, but occasionally they still run afoul of other companies. Not long ago, a Belgium based newspaper sued the giant, due to its caching of news articles and images that you could retrieve from search. While I find such features infinitely useful, the Belgium courts agreed that Google would have to proactively contact copyright owners first before doing such. They've been ordered to pay a fine and remove what they already have up:

But in the future, it said it would be up to copyright owners to get in touch with Google by e-mail to complain if the site was posting content that belonged to them. Google would then have 24 hours to withdraw the content or face a daily fine of 1,000 euros ($1,295).
How will this ruling impact other archiving? From a research point of view, preventing Google or other companies from keeping copies of digital material that may have been long since lost is a bad thing. The law, unfortunately, is not on their side with this one.
