 This system uses Traefik as a reverse proxy and can automatically handle SSL certificates:
 
 1. By default, SSL certificates are obtained from Let's Encrypt
-2. Use the domain `yourdomain.traefik.me` for testing (Traefik.me will automatically generate certificates)

+2. Use your server's IP address with traefik.me by replacing dots with hyphens, e.g., `192-168-1-100.traefik.me`
+3. This works with any public IP address and lets traefik.me automatically generate valid SSL certificates
 4. For production, use your own domain and set MAIL in .env to your email for Let's Encrypt notifications
 5. To disable SSL, set `NO_SSL=true` in your .env file

+## Backup and Restore System
+
+This repository includes a comprehensive backup and restore system for Docker volumes:
+
+### Local Backups
+
+- `backup-node.sh <config-name>` - Create a backup of all volumes for a configuration to the `/backup` directory
+- `restore-volumes.sh <config-name>` - Restore volumes from the latest backup in the `/backup` directory
+
+### Remote Backups
+
+To serve backups via HTTP and WebDAV:
+
+1. Add `backup-http.yml` to your `COMPOSE_FILE` variable in `.env`
+2. This exposes:
+   - HTTP access to backups at `https://yourdomain.tld/backup`
+   - WebDAV access at `https://yourdomain.tld/dav`
+
+### Cross-Server Backup and Restore
+
+For multi-server setups:
+
+1. On server A: Include `backup-http.yml` in `COMPOSE_FILE` to serve backups
+2. On server B: Use restore from server A's backups:
+   ```bash
+   # Restore directly from server A
+   ./restore-volumes.sh ethereum-mainnet https://serverA.domain.tld/backup/
+   ```
+
+3. Create backups on server B and send to server A via WebDAV:
+   ```bash
+   # Backup to server A's WebDAV
+   ./backup-node.sh ethereum-mainnet https://serverA.domain.tld/dav
+   ```
+
+This allows for efficient volume transfers between servers without needing SSH access.
