Developers and devops folks can certainly do this, I know I have had to do that before for my production data.

Part of the point (and the impressive software that has been built here) is that backups happen transparently, and if anything ever happens to the Helm you can get another one and get back up and running by restoring from online backups. It's the same principle: things can happen to your iPhone but you can get up and running with a new one easily.
