DIY BACKUP / THE HONEST ANSWER
Yes. You can copy your Codex data yourself.
If you are comfortable maintaining the locations, exclusions, storage, retention and recovery tests, a manual backup can be a valid choice. Remember that keeping repeated full copies can multiply storage use as your local workspace grows.
Follow the safer DIY guide- 01Find the active local workspaceConfirm the Windows locations Codex is actually using.
- 02Keep sensitive data outHandle credentials and unsafe runtime material deliberately.
- 03Plan for storage growthFull copies repeat unchanged data. Use protected storage, version history and retention you monitor.
- 04Test recovery separatelyProve the copy away from live state and repeat after meaningful changes.
Prefer not to maintain all of that?
Calmbu packages supported scope, safer defaults, AES-256-GCM encryption, storage-efficient recovery points, plan-based automation and required recovery checks into one maintained product.

Read the answer CURRENT CALMBU SCOPE
Download Native Windows Codex support. Public release still gated.
These guides are useful now while Calmbu remains behind the public Windows download gate. The current Windows build supports approved native Windows workspace data for Codex and Claude Code. Codex in WSL, cloud-only ChatGPT/Codex data, credentials, and original project files remain outside current Codex coverage.
HOW THESE ANSWERS ARE MAINTAINED
Official Codex facts, Calmbu product evidence, and explicit limits.
We distinguish what OpenAI documents from what Calmbu detects or tests. Pages are reviewed after meaningful Codex storage, Windows support, or Calmbu recovery changes. If a claim cannot be verified, it does not become a promise.
