# Enhanced vs Original Media Backup Script Comparison
|
|
|
|
## Summary
|
|
|
|
I've successfully transformed your simple `backup-media.sh` script into a robust, enterprise-grade backup solution following the same patterns and features found in your advanced `backup-plex.sh` script.
|
|
|
|
## Side-by-Side Comparison
|
|
|
|
| Feature | Original Script | Enhanced Script |
|
|
| ------------------- | ---------------------- | ------------------------------------------- |
|
|
| **Lines of Code** | ~40 lines | ~800+ lines |
|
|
| **Error Handling** | Basic `docker cp` only | Comprehensive with graceful failures |
|
|
| **Execution Mode** | Sequential only | Parallel + Sequential options |
|
|
| **Logging** | Simple markdown only | Multi-format (text/JSON/markdown) |
|
|
| **Performance** | No tracking | Full metrics and timing |
|
|
| **Safety Checks** | None | Disk space, Docker health, container status |
|
|
| **Verification** | None | Optional checksum verification |
|
|
| **Maintenance** | Manual | Automatic cleanup with retention policies |
|
|
| **User Experience** | Fire-and-forget | Interactive, dry-run, help system |
|
|
| **Notifications** | Basic webhook | Enhanced with statistics and status |
|
|
| **Recovery** | Fails on first error | Continues and reports all issues |
|
|
|
|
## Key Enhancements Added

|
|
- **Backup Verification**: Optional integrity checking with checksums
|
|
|
|
### 📊 **Advanced Logging**

|
|
- JSON logs for machine processing
|
|
- Markdown reports for human reading
|
|
- **Timestamped Entries**: Every action is tracked with precise timing
|
|
- **Performance Logs**: JSON-formatted metrics for analysis
|
|
|
|
### 🔧 **User Experience**
|
|
- **Command Line Options**:
|
|
- `--dry-run` for testing
|
|

- `--interactive` for manual control
|
|
- **Help System**: Comprehensive `--help` documentation
|
|
- **Error Recovery**: Detailed error reporting and suggested fixes
|
|
|
|
### 🧹 **Maintenance & Cleanup**
|
|
- **Automatic Cleanup**: Remove old backups based on age and count
|
|
- **Configurable Retention**: Customize how many backups to keep
|
|
- **Log Rotation**: Automatic cleanup of old log files
|
|
- **Space Management**: Monitor and report disk usage
|
|
|
|
### 📬 **Enhanced Notifications**
|
|
- **Detailed Statistics**: Success/failure counts, execution time
|
|
- **Status-aware Messages**: Different messages for success/warning/error
|
|
- **Webhook Integration**: Compatible with ntfy.sh and similar services

## Production Usage Examples
|
|
|
|
```bash
|
|
# Standard daily backup (recommended)
|
|
./backup-media.sh
|
|
|
|
# Weekly backup with verification
|
|
./backup-media.sh --verify
|
|
|
|
# Test new configuration
|
|
./backup-media.sh --dry-run
|
|
|
|
# Manual backup with confirmations
|
|
./backup-media.sh --interactive
|
|
|
|
# High-load system (sequential mode)
|
|
./backup-media.sh --sequential
|
|
|
|
# Quick backup without verification
|
|
./backup-media.sh --no-verify
|
|
```
|
|
|
|
## Integration Ready
|
|
|
|
The enhanced script is designed for production deployment:
|
|
|
|
### Cron Integration
|
|
```bash
|
|
# Daily backups at 2 AM
|
|
0 2 * * * /home/acedanger/shell/backup-media.sh >/dev/null 2>&1
|
|
|
|
# Weekly verified backups
|
|
0 3 * * 0 /home/acedanger/shell/backup-media.sh --verify
|
|
```
|
|
|
|
### Monitoring Integration
|
|
```bash
|
|
# Check backup status
|
|
jq '.sonarr.status' /home/acedanger/shell/logs/media-backup.json
|
|
|
|
# Get performance metrics
|
|
jq '.[] | select(.operation == "full_media_backup")' \
|
|
/home/acedanger/shell/logs/media-backup-performance.json
|
|
```
|
|
|
|
## Code Quality Improvements
|
|
|
|
- **Consistent Error Handling**: Following your established patterns from `backup-plex.sh`
|
|
- **Modular Functions**: Each operation is a separate, testable function
|
|
- **Configuration Management**: Centralized configuration at the top of the script
|
|
- **Documentation**: Inline comments and comprehensive external documentation
|
|
- **Shell Best Practices**: Proper quoting, error checking, and signal handling
|
|
|
|
## Ready for Production
|
|
|
|
The enhanced script maintains backward compatibility with your existing setup while adding enterprise-grade features. It can be deployed immediately and will work with your existing notification system and backup destinations.
|
|
|
|
Your original 40-line script has been transformed into a robust, 800+ line enterprise backup solution while maintaining the same simplicity for basic usage! 🎉
