I don't consider that nice-to-have. That is essential. If you do not regularly test restoring, you do not know if you have backups. I normally overstate this just a little for effect, "If you don't test your backups you don't have backups", but that isn't precisely true. And yes, it frequently makes sense to base test/fixture data and whatnot on backup data flows, but unless you don't deal with any PII, you're hopefully not using that data without a sanitization step.
