+### Disaster Recovery
+Create and restore local snapshots of `brain/`, `skills/`, `agents/`, `data/`, `registry/`, `standards/`, and `prompts/`. User-specific `data/settings.json` is excluded from backups.
+
+**Unix/macOS/Linux**
+```bash
+./backup.sh
+./restore.sh <backup-file>
+```
+
+**Windows PowerShell**
+```powershell
+.\backup.ps1
+.\restore.ps1 <backup-file>
+```
+
+Run the restore command without a backup file to list available backups.
