Summary

This PR introduces a comprehensive enhancement to CyberPanel's migration system that solves the critical issue where remote transfers require 50%+ free disk space. The current system zips all websites simultaneously, making migrations fail on servers with limited disk space.

Problem Statement

  • Current Issue: Remote transfer requires compressing ALL selected websites at once
  • Space Requirement: Needs 50%+ free disk space (original + compressed backups)
  • Impact: Migration failures on production servers with limited storage

Solution Overview

Implemented an intelligent transfer system with three modes based on available disk space:

🔄 Sequential Transfer Mode (Low Space < 50%)

  • Processes websites one-by-one with immediate cleanup
  • Minimal disk space usage (only one website at a time)
  • Slower but very reliable for space-constrained servers

⚡ Rsync Transfer Mode (Very Low Space < 30%)

  • Direct file synchronization without compression
  • Almost zero additional disk space required
  • Best for incremental transfers and very low disk scenarios

🚀 Parallel Transfer Mode (High Space > 50%)

  • Current CyberPanel method (all at once)
  • Fastest overall transfer time
  • Maintains backward compatibility

Key Features Implemented

🧠 Intelligent Mode Selection

  • Automatic disk space analysis
  • Website size calculation
  • Smart recommendations based on system resources
  • User override options

🎨 Enhanced User Interface

  • Real-time disk space visualization
  • Transfer mode compatibility indicators
  • Progress tracking with current website display
  • Modern, responsive design

📊 Enhanced Monitoring

  • Detailed transfer progress
  • Disk usage tracking during transfers
  • Comprehensive error logging
  • Transfer cancellation support

Files Added

  • plogical/enhancedRemoteTransfer.py - Core transfer engine
  • backup/templates/backup/enhancedRemoteTransfer.html - Modern UI
  • backup/static/backup/enhancedRemoteTransfer.js - Interactive frontend
  • backup/views/enhancedRemoteTransfer.py - API endpoints
  • backup/urls/enhancedRemoteTransfer.py - URL routing
  • docs/ENHANCED_REMOTE_TRANSFER.md - Complete documentation
  • backup/requirements_enhanced.txt - Dependencies

Backward Compatibility

  • Fully backward compatible with existing migration system
  • Maintains all current functionality
  • Uses existing authentication and security
  • No breaking changes to existing workflows

Benefits

  • Reduced failed migrations due to disk space issues
  • Better resource utilization during transfers
  • Incremental transfer support with rsync
  • Real-time monitoring and control
  • Lower support tickets related to migration failures
  • Improved customer satisfaction with reliable transfers

This enhancement makes CyberPanel migrations accessible to users with any disk space availability while maintaining the excellent performance for high-resource servers.
