What sort of backup strategy is in place? Is the content safe when a machine goes down? Is everything stored on a separate storage solution, with a redundant array behind it? I'm not really going to judge based on the outcome of these questions. I simply need to know what I have to prepare for.
We host on hot swappable raid 10 disk arrays. Most likely a hard drive will fail over having an entire server fail. We keep a bunch of spare hard drives. We also do daily backups onto a separate system for disaster recovery. If a server goes down and can't be revived, then we will bring up another server with the backups.
Yes we do daily backups. But the likelihood of a server "going down" to a catastrophic degree is slim. That tends to happen more when you use cheap hardware, and we do not use cheap hardware. Component failure is a fact of life, that's the technology we all live with. It's unavoidable. We're prepared for typical failures.
