Any TOS I've seen from storage companies has clauses against violating local copyright law.

In the United States for instance, making a copy of any digital media is generally illegal, period. The two major exceptions here are if you can prove "fair use", or if you are an archive or library.

"Fair use" is, of course, a very fuzzy term. Fuzzy enough to give companies enough wiggle room to terminate if, as probably most large archives would be, a person uploaded terabytes and terabytes of copyrighted media to their drive. (If said person shares copyrighted links in particular, that usually is explicitly called out in storage TOS clauses... but even if not, I think it would be difficult to claim "fair use" for a personal upload of Soundcloud to your Google drive.)

In the Archive Team's case, it looks like the Archive Team is using the Wayback Machine from archive.org. (http://archiveteam.org/index.php?title=Dev/Infrastructure) Libraries and archives have their own set of rules allowing limited copying (https://www.law.cornell.edu/uscode/text/17/108), in addition to the general "fair use case". My guess is due to questions of Soundcloud's longevity, archiving Soundcloud would qualify.
