The cloud is great. Your stuff is stored in only one place. No copies in email attachments, no copies on your laptop, your desktop, and your server. Make a change and there's no need to send out updates, because it's always in one place. Right?
Right. But delete it in one place and it's gone. Gone. You can't just find a copy in email. Or on your laptop. It was stored in only one place, and now it's no longer there.
Loosely connected systems are messy, but they have redundancy built in. Highly connected systems are more fragile. They need explicit redundancy, explicit backup systems.
However important backup is in traditional desktop environments, its much more important in cloud-based environments.
