What's inside
Inside: what it protects against and how it works. Which rules it helps you meet. The proof your auditor will want. About 10 to 14 dense pages.
- What you're really defending against, in plain terms
- How the system works, and why an attacker can't beat it
- What it stops, with real-world examples
- Which rules apply: fines, deadlines, exact wording
- The cost math, grounded in published numbers
- How we stack up against other vendors on the tech, not the price tag
- What setup looks like, and what we don't cover
- The evidence your auditor will ask for

Who is this brief written for?
A CISO, CTO, or senior infrastructure engineer reviewing the design. It assumes you know how backups work, how storage works, and the rules your stack already has to follow.
Is there a non-technical version?
Yes. After you submit your email, the same page links to a five-minute executive PDF you can forward to a CFO, IT director, or board member.

Why btrfs?
The brief covers this in depth. Short version: btrfs puts write-once copies and instant clones into the storage layer itself. Not into an app on top. The send/receive feature ships those copies off-machine. So an attacker holding your top admin password can't change or delete them.
Does this apply to managed services like AWS RDS?
Not directly. The design covers your own servers running databases in Docker on btrfs storage. If your critical data lives in RDS or Aurora, the brief flags that. It then shows where the model fits and where it doesn't.
About this brief
