   • Leftover ISO files in the project directory
   • Temporary files in staging directories
   • Orphaned temporary files
3. Shows progress and completion summary

Configuration

Configuration is stored in ~/.config/bdarchive/config.toml:

# Blu-ray device path
device = "/dev/sr0"

# Staging directory for building ISO
staging_dir = "/tmp/bdarchive_staging"

# Database path
database_path = "~/.local/share/bdarchive/archive.db"

# Default disc capacity (GB): 25, 50, or 100
# Used for capacity planning and multi-disc calculations
default_capacity_gb = 25

# Burn configuration
[burn]
# Burn method: "direct" (space-efficient, default) or "iso" (traditional)
method = "direct"

# Verification settings
[verification]
auto_verify_after_burn = false
auto_mount = false

# Optional tools
[optional_tools]
use_qrencode = true
use_rsync = true

Disc Layout

Each disc follows a standard, mountable layout:

/
├── ARCHIVE/
│   ├── folder1/
│   │   └── ... (original structure)
│   └── folder2/
│       └── ... (original structure)
├── DISC_INFO.txt      # Disc metadata
├── MANIFEST.txt       # All file paths (one per line)
├── SHA256SUMS.txt     # SHA256 checksums (sha256sum format)
└── CRC32SUMS.txt      # Fast CRC32 checksums (optional, for speed)

This layout is:

• Mountable: Standard ISO/UDF format, mounts on any Linux system
• Browsable: Standard directory structure, no proprietary formats
• Verifiable: Contains all metadata needed for long-term verification
• Self-contained: Each disc includes its own manifest and checksums

Database Schema

The SQLite database (~/.local/share/bdarchive/archive.db) contains:

• discs: Disc metadata (ID, creation date, notes, volume label, etc.)
• files: File index (disc_id, path, SHA256, size, mtime)
• verification_runs: Verification history (disc_id, success, files checked, etc.)

The database is versioned with migrations for future schema changes.

Performance

BlueVault is optimized for speed and efficiency:

• Multi-core checksums: Parallel CRC32/SHA256 generation using all CPU cores
• Smart burn modes: Direct burn eliminates intermediate ISO files (saves ~50GB per disc)
• Fast staging: Optional rsync support for large file operations
• Memory efficient: Streaming checksum calculation for large files
• Real-time feedback: Progress updates during all long-running operations
• Intelligent media detection: Automatically handles BD-R discs misreported as BD-ROM
• Automatic cleanup: Staging directories removed after burns to save disk space

Typical performance (on a 4-core system):

• Manifest generation: ~5-10 seconds (vs ~30-60 seconds sequential)
• Direct burn: No intermediate storage required
• ISO burn: ~16 seconds for 13GB ISO creation
• Large burns: Real-time progress with accurate ETAs

Recent Improvements (v0.1.2)

Major New Features:

• Multi-Disc Archives: Complete support for splitting large archives across multiple Blu-ray discs
• Smart Directory Splitting: Preserves folder integrity while efficiently distributing content
• Sequential Disc Burning: Guided workflow for burning multi-disc sets
• ISO Path Reporting: Shows exact locations of all created ISO files
• Comprehensive Cleanup: New menu option to clean build artifacts and temporary files

Enhanced User Experience:

• Live Burn Progress: Real-time speed, time remaining, and progress for 50GB+ burns
• Smart Media Handling: BD-R discs misreported as BD-ROM are automatically handled
• Universal Quit Key: 'Q' quits from any screen, 'Esc' navigates back
• Automatic Cleanup: Staging files removed after successful/failed burns
• Unique Disc IDs: Database-aware sequential ID generation prevents conflicts
• Input Field Fixes: All keyboard input now works properly in text fields
• Clean UI: Removed terminal corruption during progress updates

Technical Improvements:

• Advanced Planning Algorithm: Greedy bin-packing for optimal disc utilization
• Multi-Disc Database Schema: Tracks relationships between discs in sets
• Enhanced Progress Feedback: Detailed status updates during all operations
• Robust Error Handling: Comprehensive error recovery and user feedback
• Background Processing: Non-blocking operations with real-time progress
• Cross-Platform Distribution: Docker, build scripts, and CI/CD support
• Enhanced Nix Flake: Complete development environment with all tools

Safety Notes

⚠️ WARNING: Burning discs is destructive!

1. Verify Device: Always verify /dev/sr0 (or your configured device) is your Blu-ray writer

   • Check with: lsblk or ls -la /dev/sr*
   • The app will use your configured device path

2. Review Content: Check the staged content before burning

3. Backup Important Data: Always maintain backups before archiving

4. Verify After Burning: Use the "Verify Disc" feature after burning important data

5. Device Permissions: You may need to add your user to the cdrom group:

   sudo usermod -a -G cdrom $USER
   newgrp cdrom  # or logout/login
