Settings -> System -> Config backups gains a Compare view: a backup against the
running config, a backup against the one before it, or any two backups. Each
differing file lists its changed keys as before/after, plus files that appeared
or vanished. GET /api/config-backups/diff?from=&to= serves it (`to` defaults to
`current`; admin only in multi-user mode).
Credential values are never returned: .env, users.json and push-keys.json report
names only, and any other key that looks like a token, secret, password,
credential or key is reported as changed without its value. A non-JSON file
reports only that it differs, a file is cut at 200 changes, and a self-refreshed
discovery timestamp does not count as a difference.
custom-model-hosts.json carries a lastDiscoveredAt per host that the 5-minute model
discovery poll rewrites, so the content hash never matched the latest snapshot and a
snapshot was written every tick. At the default keep count of 20 that left about 100
minutes of history and evicted every useful older copy.
The change check now looks through volatile keys per tracked file. The snapshot still
stores the file as written and restore still verifies against its own digest.
- New wiki page Config-Backups: what is backed up (and what is not, and why), when a backup is made,
where and under what name (cfg-YYYYMMDD-HHMMSS, manifest.json, reasons), retention and its
guarantees, the Settings controls, restore (verify, pre-restore copy, atomic write, which files
need a restart), security, the HTTP API and troubleshooting.
- Linked from the Home index and sidebar; Settings Reference, Troubleshooting ("my settings were
reset"), Security and Core Concepts updated; README and CLAUDE.md entries; the api-reference
section now states the naming convention and the full tracked list.
- Found while documenting: remote-hosts.json, docker-hosts.json, docker-cases.json and
webviews.json are user configuration too and were not tracked; they are now. state.json stays
out on purpose (rewritten per session event, also holds cron jobs and respawn presets) and the
docs say so.
