This is what stood out to me. I've no actual experience operating in this area, but I have been a very grateful user recipient of backups. Anyway, I thought backups were a nightly thing....? Particularly if that data is essentially your business.

Presumably it costs a bit to set up but it surely it's unacceptable not to set it up?

Hourly or even more frequently is commonplace because transaction log backups are relatively cheap to take and keep, especially in the era of blob storage. In the olden days, tape drives couldn't keep up this level of backup schedule because they're bad at frequent stop-starts and interleaving a bunch of unrelated transaction logs would make recovery very slow. This just isn't an issue any more and anybody competent is backing up multiple times per day.
