A stunningly beautiful Terminal backup and restore tool built with Bubble Tea and Lipgloss. Features Tokyo Night theming, pure Go implementation with zero external dependencies, and production-ready performance with selective backup capabilities.

🔥 Live System Backup & Restore

The game changer: Migrate backs up and restores running live systems - no downtime required.

Unlike traditional tools that require booting from external media (looking at you, CloneZilla), Migrate works seamlessly on your active, running OS. When you're ready to restore, simply:

1. Fresh install your OS
2. Run the restore
3. 💥 You're back up and running - exactly as you left it

No external boot disks. No system downtime. Just pure magic. ✨

✅ Production Ready: Recently underwent extensive optimization and bug fixes. All major performance and reliability issues have been resolved as of July 2025.

⚙️ How It Works

rsync --delete Equivalent

Performs the equivalent of rsync -aAx --delete / /backup/destination/ but with:

• rsync-style file comparison - Intelligent size + timestamp checking (50-80% faster than SHA256)
• Modern buffer optimization - 256KB-4MB adaptive buffers optimized for SSD/NVMe storage
• SHA256 verification - Available for cryptographic verification when needed
• Better logging - Detailed statistics on copied vs. skipped files
• Zero dependencies - No rsync binary required
• Beautiful interface - Progress tracking and status updates
• Smart exclusions - Optimized pattern matching for maximum performance

Smart Features

• rsync-style comparison - Skip identical files using size + timestamp (50-80% faster than SHA256)
• Incremental backups - Only copy changed/new files with intelligent comparison
• Modern I/O optimization - 256KB-4MB adaptive buffers for maximum SSD/NVMe throughput
• Smart exclusions - Optimized pattern matching without affecting deletion phase
• Automatic exclusions - /dev, /proc, /sys, /tmp, backup destination
• Progress accuracy - File-based tracking: (processed / total) * 85% + cleanup * 15%
• Complete --delete behavior - Properly removes stale files from backup regardless of exclusions
• Performance optimization - Combined optimizations deliver 70-120% speed improvement

⚡ Performance Comparison
