‘“Covered Book” shall mean any in-copyright book or portion thereof, whether in existence as of the date hereof or later created, in which any Plaintiff (or any subsidiary or corporate affiliate of a Plaintiff) (a) owns or controls an exclusive right under the Copyright Act …’

‘the “Internet Archive Parties” … are permanently enjoined and restrained from engaging in any of the following acts in, from or to the United States … the distribution to the public, public display, and/or public performance, of Covered Books in, from or to the United States in Case 1:20-cv-04160-JGK-OTW Document 214-1 Filed 08/11/23 Page 3 of 6 any digital or electronic form, including without limitation on the Internet Archive website (collectively “Unauthorized Distribution”)’

So while backing up the entire lending library might have been a challenge, perhaps the books of just the plaintiff publishers can be backed up?

Might also be an opportunity to punish the publishers by distributing their copyrighted works and hurting their pocket (though it seems they're still yet to prove that piracy actually hurts profits!)
