# Fathom VM Recovery Guide

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

```bash
systemctl status fathom-vllm.service --no-pager
curl http://127.0.0.1:8000/v1/models
curl http://127.0.0.1:7860/health
curl -I http://127.0.0.1:3000/
curl http://127.0.0.1:3000/demo.html
