What's inside

Inside: what it protects against and how it works. Which rules it helps meet. The proof an auditor will want. About 10 to 14 dense pages.

  1. What the real threat is, in plain terms
  2. How the system works, and why an attacker can't beat it
  3. What it stops, with real-world examples
  4. Which rules apply: fines, deadlines, exact wording
  5. The cost math, grounded in published numbers
  6. How we stack up against other vendors on the tech, not the price tag
  7. What setup looks like, and what we don't cover
  8. The evidence an auditor will ask for

Backups that ransomware can’t touch

Backups lock the moment they're made. No one can change them. Not hackers. Not even the owner.

Test OS updates without the risk

Make a copy of the live servers. Install the update on the copy. See what breaks. If it goes wrong, throw the copy away. The real servers never get touched.

Questions readers asked

Who is this brief written for?

A CISO, CTO, or senior infrastructure engineer reviewing the design. It assumes working knowledge of backups, storage, and the rules the stack already has to follow.

Is there a non-technical version?

Yes. After the email is submitted, the same page links to a five-minute executive PDF, ready to forward to a CFO, IT director, or board member.

What happens to my email?

One confirmation email, plus our newsletter (one short post per month, all-product). Unsubscribe with one click. Email addresses live in the EU by default per Rediacc's data-residency policy.

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 the top admin password can't change or delete them.

Does this apply to managed services like AWS RDS?

Not directly. The design covers self-hosted servers running databases in Docker on btrfs storage. When 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
