Archiving a page should be pretty safe as long as the archived copy is only for internal use, that means something like OTRS. If the archived copy is republished it _might_ be viewed as a copyright infringement.

Still note that the archived copy can be used for automatic verification, ie extract a quote and check that against a stored value, without infringing any copyright. If a publication is withdrawn it might be an indication that something is seriously wrong with the page, and no matter what the archived copy at WebCitation says the page can't be trusted.

Its really a very difficult problem.
