There was no "backup" in the film days. If there was spoilage for some reason or other, it was likely the entire roll was bad. Early digital cameras also didn't have dual slots.
I've had cards go bad—only two, and both were from a known bad batch—otherwise, I've had a few corrupted images out of many hundreds of thousands over the last 17 years. The percentage of ruined shots due to media is certainly less than the percentage of missed shots / bad processing from film.
Though I tend to go toward the -1D series (at least, before I retired from that biz), I'd have no qualms about shooting a fairly "cheap" single-slot camera at weddings or other events. At that price, I could hang two around my neck and alternate every few shots.
