Backups are always considered to be too expensive up until the point that not having backups becomes more expensive. This applies to redundancy of all kinds except the one that means firing employees for not setting up the other kinds.
Even at home. I do one usb backup and one internal backup of photos, home videos and documents. I would love to make backups of other stuff, but I can replace a lot of the other crap if need be, because hard drives kinda stalled in price drops.
