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.
Untested updates cause outages
Patching is mandatory. But every update is a gamble. Will it break something? Nobody knows until it's live. So the work waits for a quiet weekend, and then it crashes at 2 a.m. and the rebuild runs all night. Most teams skip patches or test on servers that don't match the real ones. Neither one works.

What does skipping patches cost?
Drag the sliders to match the infrastructure. See the risk of untested updates.
One command. Zero risk.
Clone
Run one command. An exact copy of the live setup spins up in 60 seconds.
Test
Install patches, upgrades, kernel updates. Break things on purpose. The real servers stay safe.
Confirm
Health checks pass? Apply the same update to the real servers. They fail? Delete the copy. Nothing happened.
Why safe testing works at the storage level
Rediacc copies a whole live setup in seconds. That means the operating system, the apps, the databases, and all the settings. The copy runs on its own isolated network with its own Docker. Patches on the copy never touch the real servers. If the copy breaks, delete it. If it works, apply the same patch for real.
Why safe testing works at the storage level
| Traditional approach | Rediacc (btrfs storage engine) |
|---|---|
| Staging server: kept by hand, drifts from the real setup within days | Instant copy of the live setup: identical by design, zero drift |
| Test VM: partial copy, missing data, different kernel | Full copy: same OS, kernel, containers, databases, settings |
| Blue-green deploy: needs 2x the servers, all the time | Copy on demand: almost no extra storage, exists only during the test |
| Canary deploy: still runs untested code on some real traffic | Isolated copy: zero real traffic exposed, fully separate network |
What it includes
Zero-risk patching
Test every update on an exact copy before going live. Break the copy, not the real servers. A daily check runs on its own and confirms the backups still work. Something fails? An alert lands before it hurts.
Production-identical
The test copy matches the live setup exactly. Same OS, same kernel, same data, same settings. No nasty surprises at go-live.
Instant rollback
Something goes wrong? The copy is throwaway. Delete it with one command. The real servers were never at risk. No rollback steps. No downtime.

Skip the deep-dive. Grab the five-minute version, short enough to read at a stand-up.

Staging servers drift out of sync. Test VMs are missing data. Only Rediacc copies a full live stack to test patches.
