+Backup timestamp: `20260417_053924`
+HF dataset: `umer07/vllm-deployement-backup`
+
+This backup matches the live VM after the current vLLM, backend, dashboard, log endpoint, classifier, RAG-context, demo HTML, and upload-flow changes.
+
+## Current Runtime
+
+- Dashboard: port `3000`
+- Backend: port `7860`
+- vLLM OpenAI-compatible endpoint: port `8000`
+- vLLM service: `fathom-vllm.service`
+- vLLM start script: `/usr/local/bin/fathom-vllm-start`
+- vLLM model id exposed to backend: `fathom-base`
+- vLLM max context configured: `32768`
+- Main app root: `/opt/fathom`
+- Public demo HTML: `/opt/fathom/dashboard/public/demo.html`
+- Root dashboard route redirects to `/demo.html`

+## Restore
+
+Use the restore script on a ROCm/vLLM-capable VM:
+
+```bash
+apt update
+apt install -y docker.io docker-compose-v2 python3 python3-pip curl
+python3 -m pip install --break-system-packages -U huggingface_hub
+
+HF_TOKEN='<your token>' bash restore_fathom_vm.sh --download-latest --start
+```
+
+The restore expects the DigitalOcean vLLM ROCm base container named `rocm` or an equivalent ROCm/vLLM container that supports `/opt/venv/bin/vllm`.
+The large Hugging Face model cache under `/shared-docker/hf-cache` is intentionally excluded and will be repopulated from Hugging Face.
+
+## Verify
