+# Backups
+
+## Purpose
+How Hermes's own configuration/state gets backed up, and what's missing.
+
+## Current mechanism
+- **`hermes backup` CLI** (verified via `hermes backup --help`): creates a zip of the entire Hermes config, skills, sessions, and data (excludes the hermes-agent codebase itself).
+  - `--quick` / `-q`: fast snapshot of just critical state (`config`, `state.db`, `.env`, `auth`, `cron`)
+  - `--label` / `-l`: label for a quick snapshot
+  - `--output` / `-o`: custom output path (default `~/hermes-backup-<timestamp>.zip`)
+- **Config keys** (`updates:` section of `~/.hermes/config.yaml`):
+  - `pre_update_backup: false` — Hermes does **not** automatically back up before self-updates
+  - `backup_keep: 5` — retention count (applies to config.yaml.bak* rotation seen during updates, e.g. in [[runbooks/update-hermes-safely]])
+  - `non_interactive_local_changes: stash`
+
+## Evidence on disk (2026-07-22)
+- One manual full backup exists: `/home/hermes/hermes-backup-2026-07-22-180830.zip` (~235 MB), same day as wiki creation.
+- `/home/hermes/wiki-personal-backups/` holds an earlier snapshot of the wiki itself (`SCHEMA.md`, `current-state.md`, `index.md`, `log.md` from 17:34, before later same-day wiki edits) — see [[runbooks/backup-wiki]].
+- `/home/hermes/hermes-wiki/` exists but is empty — likely a staging/rename artifact from wiki setup, not an active backup target.
+- A dedicated memory-backup script exists: `/home/hermes/.hermes/scripts/mnemosyne-backup.sh` — see [[systems/mnemosyne]].
+
+## Known gaps
+- **No scheduled backup job found:** `crontab -l -u hermes` returns empty, and no systemd timer references `hermes` or `backup`. The one full backup on disk appears to have been triggered manually, not on a schedule.
+- `pre_update_backup: false` means an in-place `hermes update` will not auto-snapshot first — the manual step in [[runbooks/update-hermes-safely]] step 1 is currently the only safety net.
