Here’s more about the vision behind VaultPress from Matt Mullenweg’s announcement post:
The vision of VaultPress is to ensure that blogs and sites under its care are always completely secure, regardless of what happens. Today, this means every bit of content will be safe, from plugins and themes to the smallest comment or post revision, with WordPress-aware, real-time, multi-cloud backups. This is some of the most advanced technology I’ve seen interact with WordPress.
In the future, if your site is tampered with in any way, we’ll know within minutes and can take appropriate steps. The VaultPress core engine will be able to protect you against zero-day security vulnerabilities by updating your blog with hot-fixes, even while you sleep.
We built VaultPress to take the worry out of managing WordPress. We hope you’ll check out the beta and let us know what you think.
