BACKUP_DIR="/backup/rustdesk"
DATE=$(date +%Y%m%d_%H%M%S)

# Create backup directory
mkdir -p $BACKUP_DIR 

# Backup configuration files
tar -czf $BACKUP_DIR/config-$DATE.tar.gz /opt/rustdesk/*.toml /opt/rustdesk/id_ed25519*

# Backup database (if using API server)
if [ -f /data/db.sqlite3 ]; then
    cp /data/db.sqlite3 $BACKUP_DIR/db-$DATE.sqlite3
fi

# Backup logs
tar -czf $BACKUP_DIR/logs-$DATE.tar.gz /var/log/rustdesk/

# Cleanup old backups (keep 30 days)
find $BACKUP_DIR -name "*.tar.gz" -mtime +30 -delete
find $BACKUP_DIR -name "*.sqlite3" -mtime +30 -delete

echo "Backup completed: $DATE"

Update Process

  • Stop services:
sudo systemctl stop rustdesk-relay rustdesk-signal
  • Backup current installation:
cp -r /opt/rustdesk /opt/rustdesk-backup-$(date +%Y%m%d)

  • Restart services:
sudo systemctl start rustdesk-relay rustdesk-signal
sudo systemctl status rustdesk-relay rustdesk-signal
  • Monitoring
#!/bin/bash
# Monitoring script

# Check service status
if ! systemctl is-active --quiet rustdesk-relay; then
    echo "RustDesk relay service is down!"
    # Send alert or restart service
fi

if ! systemctl is-active --quiet rustdesk-signal; then
    echo "RustDesk signal service is down!"
    # Send alert or restart service
fi

# Check port connectivity
if ! nc -z localhost 21115; then
    echo "Relay port 21115 is not accessible!"
fi

if ! nc -z localhost 21116; then
    echo "Signal port 21116 is not accessible!"
fi

# Check disk space
DISK_USAGE=$(df /opt/rustdesk | tail -1 | awk '{print $5}' | sed 's/%//')
if [ $DISK_USAGE -gt 80 ]; then
    echo "Disk usage is above 80%: ${DISK_USAGE}%"
fi

# Check memory usage
MEMORY_USAGE=$(free | grep Mem | awk '{printf "%.0f", $3/$2 * 100.0}')
