FWIW I've studied copyright informally in UK, USA, and to a lesser extent other countries.

In UK our "Fair Dealing" is highly restrictive compared to USA's Fair Use.

Our (UK) archiving rights extend only to a couple of institutions and then only to people attending the library in person. We don't have rights to make backups; we don't have rights to format shift (except to help the disabled).

Yes, copyright specifics apply but wrt archiving USA is far from the most restrictive regime.
