Security and Backups for a Self-Built Private AI
Short answer: The build needs a login, and its API keys and tokens must not be stored in plain text. Keep your data backed up somewhere you control, test that the backup restores, and rotate keys and tokens as part of the weekly upkeep.
What the pillar page requires
Two parts sit inside the steps of the full guide. Secure it: the build needs a login, and its API keys and tokens must not be stored in plain text. And keep the data backed up somewhere you control, test that the backup restores, and rotate keys and tokens as part of the weekly upkeep.
Plain text is the named failure twice over: the harness step warns about login and API keys stored in plain text, and the security note repeats it. If a key lives in a file anyone with the box can read, the login in front of the interface is doing less than it looks like.
What the Freeborn homepage states about its own build
Stated about the done-for-you build, and a fair checklist to hold your own build to: connections use HTTPS, stored keys are encrypted, it runs in your own cloud account and they do not train on your data. The same page is explicit about the limit: they do not claim end-to-end encryption, because the GPU host and the model process your text while it runs.
That limit applies to a DIY build too. The host you rent can process what the model processes. Choosing the host — and knowing what its terms allow it to do — is part of keeping the setup safe, not a separate topic.
Backups, stated as practice
As general practice, stated as practice and not as a measured claim: keep the backup somewhere you control rather than only on the rented box, keep the restore script with it, and run the restore on a schedule instead of trusting that it would work. The failover page covers the move itself; this page's point is simpler — a backup you never restored is not yet a backup.
When a host closes an account, keys that still work on the old host are part of the clean-up. Rotating keys weekly, as the upkeep page describes, keeps that list short.
