>a copy of the existing 4chan content
4chan's content is ephemeral. Most of it is gone every few days.
That's how it used to be (and the vast majority of early content is indeed lost). Most boards were auto-archived starting in the mid/late 2010s, though, with many archives being searchable. Some even allow ghost posting.
