+# NFS Archiving Support (marcone#1004) - Functionality and Benefits
+
+## Overview
+
+NFS (Network File System) Archiving Support is a network-based archiving solution for TeslaUSB that enables automatic backup of Tesla Sentry Mode and Dashcam recordings to NFS network shares. This feature provides an alternative to CIFS/SMB (Windows file sharing) for users who prefer or require NFS-based storage solutions.
+
+## Functionality
+
+### What is NFS Archiving?
+
+NFS is a distributed file system protocol originally developed by Sun Microsystems that allows remote access to files over a network. The NFS archiving implementation in TeslaUSB provides:
+
+1. **Automatic Recording Archiving**: When your Tesla connects to your home WiFi network, TeslaUSB automatically copies dashcam footage to a configured NFS share on your network-attached storage (NAS) or file server.
+
+2. **Network-Based Storage**: Unlike local storage solutions, NFS archiving allows virtually unlimited storage capacity by leveraging your existing NAS infrastructure.
+
+3. **Reliable File Transfer**: Uses rsync with NFS-specific optimizations to ensure reliable, efficient file transfers.
+
+### Key Features
+
+#### 1. **NFS Protocol Compatibility**
+- **NFSv3 Support**: Forced to version 3 for wider NAS compatibility including:
+  - Synology NAS systems
+  - QNAP NAS systems  
+  - Unifi Dream Machine/Router storage
+  - Generic Linux NFS servers
+  - TrueNAS/FreeNAS systems
+
+#### 2. **Network Stability Enhancements**
+- **TCP Protocol**: Uses TCP instead of UDP for better reliability over WiFi
+- **nolock Option**: Prevents file locking issues that can cause hangs over wireless connections
+- **Connection Monitoring**: Automatically detects and handles network disconnections during archiving
+
+#### 3. **Permission Handling**
+The implementation includes special handling for NFS permission issues:
+```bash
+# From archive-clips.sh
+rsync -avhRL --no-o --no-g --remove-source-files --no-perms --omit-dir-times
+```
+- `--no-o`: Skips ownership preservation (prevents errors on root-squashed shares)
+- `--no-g`: Skips group preservation (prevents permission errors)
+- `--no-perms`: Doesn't attempt to preserve permissions
+- `--omit-dir-times`: Skips directory timestamp updates
+
+These options are critical for NFS shares configured with "root squash" (a common security feature where root access is mapped to an anonymous user).
+
+#### 4. **Reachability Verification**
+Before attempting to archive, the system:
+- Checks if the NFS server is reachable on port 2049 (NFS standard port)
+- Verifies the share is mountable
+- Tests write permissions with a test file
+
+#### 5. **Automatic Recovery**
+- Connection monitoring kills stuck rsync processes if the network connection is lost
+- Retry mechanisms for transient network issues
+- Graceful handling of WiFi disconnections
+
+## Configuration
+
+### Basic Setup
+
+Add the following to your `teslausb_setup_variables.conf`:
+
+```bash
+# Variables for NFS archiving
+export ARCHIVE_SYSTEM=nfs
+export ARCHIVE_SERVER=your_nas_ip_or_hostname
+export SHARE_NAME='/volume1/TeslaCam'  # Exact export path on NAS
+```
+
+### Optional Music Sync
+
+```bash
+# Optional: Sync music from NFS share
+export MUSIC_SHARE_NAME='/volume1/Music'
+export MUSIC_SIZE=4G
+```
+
+### Important Notes
+
+1. **SHARE_NAME Must Be Exact**: The NFS share name must match the exact export path configured on your NAS (e.g., `/volume1/TeslaCam` on Synology)
+
+2. **Server Specification**: Can be either IP address or hostname
+   - IP recommended for faster resolution and reliability
+   - Hostname requires working DNS resolution
+
+3. **Firewall Requirements**: Ensure NFS port 2049 is accessible from the Raspberry Pi to the NAS

+  - Unifi Dream Machine/Router 存储
+  - 通用 Linux NFS 服务器
+  - TrueNAS/FreeNAS 系统
+
+#### 2. **网络稳定性增强**
+- **TCP 协议**：使用 TCP 而非 UDP，通过 WiFi 提供更好的可靠性
+- **nolock 选项**：防止文件锁定问题导致无线连接挂起
+- **连接监控**：自动检测并处理归档期间的网络断开
+
+#### 3. **权限处理**
+实现包括对 NFS 权限问题的特殊处理：
+```bash
+# 来自 archive-clips.sh
+rsync -avhRL --no-o --no-g --remove-source-files --no-perms --omit-dir-times
+```
+- `--no-o`：跳过所有权保留（防止 root-squashed 共享上的错误）
+- `--no-g`：跳过组保留（防止权限错误）
+- `--no-perms`：不尝试保留权限
+- `--omit-dir-times`：跳过目录时间戳更新
+
+这些选项对于配置了"root squash"（一种常见的安全功能，将 root 访问映射到匿名用户）的 NFS 共享至关重要。
+
+#### 4. **可达性验证**
+在尝试归档之前，系统会：
+- 检查 NFS 服务器在端口 2049（NFS 标准端口）上是否可达
+- 验证共享是否可挂载
+- 使用测试文件测试写入权限
+
+#### 5. **自动恢复**
+- 如果网络连接丢失，连接监控会终止卡住的 rsync 进程
+- 针对暂时性网络问题的重试机制
+- 优雅处理 WiFi 断开连接
+
+## 配置
+
+### 基本设置
+
+将以下内容添加到您的 `teslausb_setup_variables.conf`：
+
+```bash
+# NFS 归档变量
+export ARCHIVE_SYSTEM=nfs
+export ARCHIVE_SERVER=你的NAS的IP或主机名
+export SHARE_NAME='/volume1/TeslaCam'  # NAS 上的确切导出路径
+```
+
+### 可选音乐同步
+
+```bash
+# 可选：从 NFS 共享同步音乐
+export MUSIC_SHARE_NAME='/volume1/Music'
+export MUSIC_SIZE=4G
+```
+
+### 重要注意事项
+
+1. **SHARE_NAME 必须精确**：NFS 共享名称必须与 NAS 上配置的确切导出路径匹配（例如，Synology 上的 `/volume1/TeslaCam`）
+
+2. **服务器规范**：可以是 IP 地址或主机名
+   - 建议使用 IP 以实现更快的解析和可靠性
+   - 主机名需要工作的 DNS 解析
+
+3. **防火墙要求**：确保从 Raspberry Pi 到 NAS 的 NFS 端口 2049 可访问

+6. Click **Submit**
+7. Enable the NFS service if prompted
+8. Note the export path
+
+### Generic Linux Server
+
+1. Install NFS server:
+   ```bash
+   sudo apt-get update
+   sudo apt-get install nfs-kernel-server
+   ```
+
+2. Create export directory:
+   ```bash
+   sudo mkdir -p /export/teslacam
+   sudo chown nobody:nogroup /export/teslacam
+   sudo chmod 777 /export/teslacam
+   ```
+
+3. Edit `/etc/exports`:
+   ```bash
+   sudo nano /etc/exports
+   ```
+
+4. Add this line (replace `192.168.1.100` with your Pi's IP):
+   ```
+   /export/teslacam 192.168.1.100(rw,sync,no_subtree_check,no_root_squash)
+   ```
+
+5. Export the shares:
+   ```bash
+   sudo exportfs -ra
+   sudo systemctl restart nfs-kernel-server
+   ```
+
+## Step 2: Get Your Pi's IP Address and NAS Information
+
+### Find Your Pi's IP Address
+
+If your Pi is already set up and accessible via SSH:
+
+```bash
+hostname -I
+```
+
+Or from your router's DHCP client list.
+
+### Collect NFS Server Information
+
+You need:
+- **NFS Server IP or hostname**: e.g., `192.168.1.10` or `nas.local`
+- **Export path**: e.g., `/volume1/TeslaCam` (Synology), `/share/TeslaCam` (QNAP), or `/export/teslacam` (Linux)
+
+## Step 3: Configure TeslaUSB
+
+### Option A: During Initial Setup
+
+If you haven't set up TeslaUSB yet:
+
+1. Download the TeslaUSB image
+2. Flash it to your SD card
+3. Mount the `boot` partition
+4. Create or edit `teslausb_setup_variables.conf` in the boot folder
+5. Add the following lines:
+
+```bash
+# WiFi Configuration
+export SSID='YourWiFiName'
+export WIFIPASS='YourWiFiPassword'
+
+# NFS Archive Configuration
+export ARCHIVE_SYSTEM=nfs
+export ARCHIVE_SERVER=192.168.1.10        # Your NAS IP or hostname
+export SHARE_NAME='/volume1/TeslaCam'    # Exact NFS export path
+
+# Drive Size
+export CAM_SIZE=40G
+
+# Optional: Music sync from NFS
+# export MUSIC_SHARE_NAME='/volume1/Music'
+# export MUSIC_SIZE=4G
+```
+
+6. Save the file
+7. Eject the SD card and insert into your Pi
+8. Boot the Pi and wait for setup to complete (can take 20-30 minutes)
+
+### Option B: On Existing TeslaUSB Installation
+
+If TeslaUSB is already set up with a different archive method:
+
+1. SSH into your Pi:
+   ```bash
+   ssh pi@teslausb.local
+   # or
+   ssh pi@<pi-ip-address>
+   ```
+
+2. Become root:
+   ```bash
+   sudo -i
+   ```
+
+3. Make the filesystem writable:
+   ```bash
+   /root/bin/remountfs_rw
+   ```
+
+4. Edit the configuration file:
+   ```bash
+   nano /boot/teslausb_setup_variables.conf
+   ```
+
+5. Change the archive configuration:
+   ```bash
+   # Comment out old archive method (add # at the beginning)
+   #export ARCHIVE_SYSTEM=cifs
+   #export SHARE_USER=username
+   #export SHARE_PASSWORD='password'
+   
+   # Add NFS configuration
+   export ARCHIVE_SYSTEM=nfs
+   export ARCHIVE_SERVER=192.168.1.10
+   export SHARE_NAME='/volume1/TeslaCam'
+   ```
+
+6. Save and exit (Ctrl+O, Enter, Ctrl+X)
+
+7. Reconfigure the archive system:
+   ```bash
+   /root/bin/setup-teslausb configure
+   ```
+
+8. Reboot:
+   ```bash
+   reboot
+   ```
+
+## Step 4: Verify the Setup
+
+### Check Archive Configuration
+
+1. SSH into your Pi
+2. Become root: `sudo -i`
+3. Check if NFS is configured:
+   ```bash
+   cat /etc/fstab | grep nfs
+   ```
+   
+   You should see something like:
+   ```
+   192.168.1.10:/volume1/TeslaCam /mnt/archive nfs rw,noauto,nolock,proto=tcp,vers=3 0 0
+   ```
+
+### Test NFS Mount
+
+1. Try to mount manually:
+   ```bash
+   mount /mnt/archive
+   ```
+
+2. Check if mounted:
+   ```bash
+   df -h | grep archive
+   ```
+
+3. Test write permission:
+   ```bash
+   touch /mnt/archive/test.txt
+   ls -l /mnt/archive/test.txt
+   rm /mnt/archive/test.txt
+   ```
+
+4. Unmount:
+   ```bash
+   umount /mnt/archive
+   ```
+
+If all these steps succeed, your NFS setup is working!
+
+### Test Archiving
+
+1. Connect your Pi to your car
+2. Drive around or trigger Sentry Mode
+3. Disconnect Pi from car
+4. Wait for Pi to connect to your WiFi
+5. Check the archive logs:
+   ```bash
+   tail -f /mutable/archiveloop.log
+   ```
+
+6. Check your NAS to see if files are being transferred
+
+## Step 5: Optional - Configure Music Sync
+
+If you want to sync music from an NFS share:
+
+1. On your NAS, create a music folder with your MP3 files
+2. Set up NFS export for the music folder (same process as Step 1)
+3. Edit your TeslaUSB config:
+   ```bash
+   /root/bin/remountfs_rw
+   nano /boot/teslausb_setup_variables.conf
+   ```
+
+4. Add these lines:
+   ```bash
+   export MUSIC_SHARE_NAME='/volume1/Music'  # Your music NFS export path
+   export MUSIC_SIZE=4G                       # Size of music drive
+   ```
+
+5. Reconfigure:
+   ```bash
+   /root/bin/setup-teslausb configure
+   ```
+
+6. Reboot:
+   ```bash
+   reboot
+   ```
+
+## Troubleshooting
+
+### "Archive server unreachable on port 2049"
+
+**Possible causes:**
+- NFS service not running on NAS
+- Firewall blocking port 2049
+- Wrong IP address
+
+**Solutions:**
+1. Verify NFS service is running on your NAS
+2. Check firewall settings on NAS
+3. Try pinging the NAS from your Pi:
+   ```bash
+   ping 192.168.1.10
+   ```
+4. Check if port 2049 is accessible:
+   ```bash
+   nc -zv 192.168.1.10 2049
+   ```
+
+### "Unable to mount archive share via NFS"
+
+**Possible causes:**
+- Wrong export path
+- Pi's IP not allowed in NFS permissions
+- NFS export not configured correctly
+
+**Solutions:**
+1. Verify the exact export path on your NAS
+2. Check NFS export permissions - ensure your Pi's IP is allowed
+3. Check NAS logs for NFS errors
+4. Try mounting manually with verbose output:
+   ```bash
+   mount -v -t nfs 192.168.1.10:/volume1/TeslaCam /mnt/archive -o rw,proto=tcp,vers=3
+   ```
+
+### "Archive share is not writeable"
+
+**Possible causes:**
+- NFS export configured as read-only
+- Permission/ownership issues
+- Squash settings preventing write
+
+**Solutions:**
+1. Verify NFS export has read/write permissions
+2. Check if you can create files manually when mounted
+3. Adjust squash settings on NAS (try "No squash" or "Map all users to admin")
+4. Check NAS disk space
+
+### Files not transferring
+
+**Check logs:**
+```bash
+tail -100 /mutable/archiveloop.log
+```
+
+**Common issues:**
+- Not enough space on NAS
+- Network connectivity issues
+- Pi not connecting to WiFi
+
+**Solutions:**
+1. Verify NAS has free space
+2. Check WiFi connection:
+   ```bash
+   iwconfig
+   ```
+3. Manually trigger archiving:
+   ```bash
+   touch /tmp/archive_is_reachable
+   ```
+
+### Slow transfers
+
+**Possible causes:**
+- Using NFSv4 instead of NFSv3
+- Not using TCP
+- Weak WiFi signal
+
+**Solutions:**
+1. Verify mount options force NFSv3 and TCP (check `/etc/fstab`)
+2. Improve WiFi signal strength
+3. Consider using wired Ethernet (Pi 3/4 with Ethernet adapter)
+
+## Advanced Configuration
+
+### Using Static IP for Pi
+
+To ensure consistent connection, assign a static IP to your Pi:
+
+1. Edit dhcpcd.conf:
+   ```bash
+   /root/bin/remountfs_rw
+   nano /etc/dhcpcd.conf
+   ```
+
+2. Add at the end:
+   ```
+   interface wlan0
+   static ip_address=192.168.1.100/24
+   static routers=192.168.1.1
+   static domain_name_servers=192.168.1.1
+   ```
+
+3. Save and reboot
+
+### Monitoring Archive Status
+
+Check archive status via web interface:
+1. Navigate to `http://teslausb.local` or `http://<pi-ip>`
+2. View recent archives and status
+
+Or via SSH:
+```bash
+tail -f /mutable/archiveloop.log
+```
+
+## Security Considerations
+
+1. **Network Security**: Ensure your WiFi network is secure (WPA2/WPA3)
+2. **NFS Permissions**: Only allow your Pi's IP in NFS export rules
+3. **Firewall**: Configure NAS firewall to only accept NFS connections from trusted IPs
+4. **Encryption**: NFS doesn't encrypt data in transit - ensure network is trusted
+5. **Physical Security**: Secure your Pi to prevent unauthorized access
+
+## Performance Tips
+
+1. **Use Wired Ethernet**: If possible, connect Pi via Ethernet for faster, more reliable transfers
+2. **WiFi 5GHz**: If your Pi supports it, use 5GHz WiFi for better performance
+3. **Reduce CAM_SIZE**: Smaller cam size means faster archiving
+4. **Regular Archiving**: Set shorter `ARCHIVE_DELAY` to archive more frequently with less data
+5. **NAS Performance**: Ensure your NAS isn't under heavy load during archiving
+
+## Next Steps
+
+- Set up push notifications to know when archiving completes: [Configure Notifications](ConfigureNotificationsForArchive.md)
+- Customize which clips to archive (SavedClips, SentryClips, etc.)
+- Set up automatic clip processing with tesla_dashcam
+- Configure the web interface for remote viewing
