# 🎬 Radarr - Container 105

## Overview

Radarr automates the discovery, downloading, renaming, and management of movie files. In this homelab, Radarr runs **natively inside an unprivileged LXC container** on Proxmox (not Docker), and integrates with qBittorrent and Jackett. Plex is notified via webhook after successful imports.

## Configuration

- **Indexer**: Jackett (Torznab URL)
- **Download Client**: qBittorrent at `192.168.1.47:8080`
  - **Username / Password**: `admin` / `pcideas`
  - **Remote Path Mapping**: `/mnt/ssd_downloads` (host) → `/downloads` (Radarr)
  - **Share Limit Action**: `Pause` (ensures import + cleanup works)

## Import Behavior

  - SSL settings (disabled)
  - Authentication method (Forms)
  - API key
- **Web UI Behavior**:
  - `LaunchBrowser`: false
  - `UrlBase`: empty
  - `Branch`: master

## Backup & Recovery

- **Backup Target**: `/var/lib/radarr`
- **Strategy**: Scheduled LXC container snapshots + optional tarball or rsync
- **Manual Backup Command**:
  ```bash
  tar -czvf /root/radarr-config-backup-$(date +%F).tar.gz /var/lib/radarr
  ```
- **Restore**: Extract and restart the Radarr service

## Updates

To update manually:

```bash
systemctl stop radarr
curl -Lo /tmp/radarr.tar.gz https://services.radarr.video/v1/download/main/latest?os=linux&arch=x64
tar -xvzf /tmp/radarr.tar.gz -C /tmp/radarr-update
cp -r /tmp/radarr-update/* /opt/Radarr/
chown -R root:root /opt/Radarr
systemctl start radarr
```

## Systemd Service File

## Notes

- Hardlinking is disabled
- All media mounts are SMB-backed ZFS datasets
- Remote path mapping is required due to separate qBittorrent container
- Integration with Plex is via webhook
- Config and logs are stored in `/var/lib/radarr`
- Radarr runs as `root` which simplifies file access across mounts
