+# 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            |

+## Configuration
+
+### Environment Variables
+The script uses several configurable parameters at the top of the file:
+
+```bash
+# Retention settings
+MAX_BACKUP_AGE_DAYS=30        # Delete backups older than 30 days
+MAX_BACKUPS_TO_KEEP=10        # Keep only 10 most recent backups
+
+# Directory settings
+BACKUP_ROOT="/mnt/share/media/backups"
+LOG_ROOT="/mnt/share/media/backups/logs"
+
+# Feature toggles
+PARALLEL_BACKUPS=true         # Enable parallel execution
+VERIFY_BACKUPS=true          # Enable backup verification
+PERFORMANCE_MONITORING=true  # Track performance metrics
+```
+
+### Services Configuration
+The script automatically detects and backs up these services:
+
+| Service        | Container Path                          | Backup Content        |
+| -------------- | --------------------------------------- | --------------------- |
+| Sonarr         | `/config/Backups/scheduled`             | Scheduled backups     |
+| Radarr         | `/config/Backups/scheduled`             | Scheduled backups     |
+| Prowlarr       | `/config/Backups/scheduled`             | Scheduled backups     |
+| Audiobookshelf | `/metadata/backups`                     | Metadata backups      |
+| Tautulli       | `/config/backups`                       | Statistics backups    |
+| SABnzbd        | `/config/sabnzbd.ini`                   | Configuration file    |
+| Jellyseerr     | `/config/db/` + `/config/settings.json` | Database and settings |
+

+```
+
+## Notifications
+
+The script supports webhook notifications (compatible with ntfy.sh and similar services):
+
+```bash
+# Default webhook
+WEBHOOK_URL="https://notify.peterwood.rocks/lab"
+
+# Custom webhook via command line
+./backup-media.sh --webhook "https://your-notification-service.com/topic"
+```
+
+Notification includes:
+- Backup status (success/failure)
+- Number of successful/failed services
+- Total execution time
+- Hostname for identification
+
+## Performance Monitoring
+
+When enabled, the script tracks:
+- Individual service backup duration
+- Overall script execution time
+- Timestamps for performance analysis
+- JSON format for easy parsing and graphing
+
+Example performance log entry:
+```json
+{
+  "timestamp": "2025-05-25T14:30:22-05:00",
+  "operation": "backup_sonarr",
+  "duration": 45,
+  "hostname": "media-server"
+}
+```
+
+## Error Handling
+
+The script provides robust error handling:
+
+1. **Container Health**: Checks if Docker containers are running
+2. **Disk Space**: Verifies sufficient space before starting
+3. **Docker Access**: Ensures Docker daemon is accessible
+4. **Verification**: Optional integrity checking of backups
+5. **Graceful Failures**: Continues with other services if one fails
+
+## Integration
+
+### Cron Job
+Add to crontab for automated daily backups:
+```bash
+# Daily at 2 AM
+0 2 * * * /home/acedanger/shell/backup-media.sh >/dev/null 2>&1
+
+# Weekly full backup with verification
+0 3 * * 0 /home/acedanger/shell/backup-media.sh --verify
+```
+
+### Monitoring
+Use the JSON logs for monitoring integration:
+```bash
+# Check last 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
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Container Not Running**
+   ```
+   WARNING: Container 'sonarr' is not running
+   ```
+   - Verify the container is running: `docker ps`
+   - Start the container: `docker start sonarr`
+
+2. **Permission Denied**
+   ```
+   ERROR: Backup failed for sonarr
+   ```
+   - Check Docker permissions
+   - Verify backup directory permissions
+   - Ensure script has execute permissions
+
+3. **Disk Space**
+   ```
+   ERROR: Insufficient disk space
+   ```
+   - Free up space in backup directory
+   - Adjust `MAX_BACKUP_AGE_DAYS` for more aggressive cleanup
+   - Run manual cleanup: `find /mnt/share/media/backups -mtime +7 -delete`
+
+### Debug Mode
+For troubleshooting, run with verbose output:
+```bash
+# Enable debugging
+bash -x ./backup-media.sh --dry-run
+
+# Check specific service
+docker exec sonarr ls -la /config/Backups/scheduled
+```
+
+## Comparison with Original Script
+
+| Feature        | Original        | Enhanced                          |
+| -------------- | --------------- | --------------------------------- |
+| Error Handling | Basic           | Comprehensive                     |
+| Logging        | Simple text     | Multi-format (text/JSON/markdown) |
+| Performance    | No tracking     | Full metrics                      |
+| Verification   | None            | Optional integrity checking       |
+| Execution      | Sequential only | Parallel and sequential modes     |
+| Notifications  | Basic webhook   | Enhanced with statistics          |
+| Cleanup        | Manual          | Automatic with retention policies |
+| Safety         | Limited         | Dry-run, pre-flight checks        |
+| Documentation  | Minimal         | Comprehensive help and docs       |
+
+## Security Considerations
+
+- Script runs with user permissions (no sudo required for Docker operations)
+- Backup files inherit container security context
+- Webhook URLs should use HTTPS for secure notifications
+- Log files may contain sensitive path information
+- JSON logs are readable by script owner only
+
+## Future Enhancements
+
+Potential improvements for future versions:
+- Database integrity checking for specific services
+- Compression of backup archives
+- Remote backup destinations (S3, rsync, etc.)
+- Backup restoration functionality
+- Integration with monitoring systems (Prometheus, etc.)
+- Encrypted backup storage
+- Incremental backup support
