antirez put a lot of work in around Redis 3.0 (iirc) to make the persistence reliable and strong. As long as your server is configured and used correctly (obviously a large caveat, but you can only hold someone's hand so much), I don't think there is any reason to doubt Redis's persistence anymore.

It's important to make this distinction because there are commonly-used systems that offer a best-effort style persistence that usually works fine, but explicitly warn developers not to trust it, and developers rarely understand that.

We badly need to get better at distinguishing between true, production-level data integrity and "probably fine".
