Q Backup Manager: A Modular Bash Backup Script Powered by Amazon Q Developer

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Crushing the Command Line

What I Built

I built a modular, automated backup script in Bash called Q Backup Manager that allows developers and sysadmins to back up important files and directories easily and efficiently. This script includes:

• Configurable source and destination paths
• Dry-run mode to preview the backup process
• Color-coded logging for easy readability
• Optional cron integration for scheduled backups
• Built with Amazon Q Developer CLI as a coding companion

It solves the common problem of forgetting to back up configuration files, codebases, or logs during fast-paced development — especially in environments where GUIs are unavailable (e.g., WSL, servers, containers).

Demo

Here are a few screenshots showcasing the tool in action:

Backup Success

To test the script locally:

git clone https://github.com/Puru54/q-backup-manager.git
cd q-backup-manager
chmod +x backup.sh
./backup.sh --dry-run

Code Repository

🔗 GitHub Repo: https://github.com/Puru54/q-backup-manager

Contains:

• backup.sh: the main Bash script
• README.md: usage, features, and setup instructions
• screenshots/: demo images for documentation and presentation

How I Used Amazon Q Developer

Amazon Q Developer acted as my AI pair programmer during the creation of this tool. Here's how I used it:

1. Script Review & Optimization
   
   I asked Q to analyze my backup.sh file. It offered valuable recommendations:

   • Refactor the script into logical functions
   • Add modular logging
   • Improve error handling

2. Debugging Logic
   
   Amazon Q helped identify a subtle issue in the dry-run mode and suggested a more reliable way to structure the rsync flags.

“I asked Q to optimize my backup logic for modularity and logging — and it delivered.”

Conclusion

This project makes my day-to-day development work much smoother by ensuring my local and server files are backed up reliably. The Amazon Q Developer CLI didn’t just speed up development — it taught me best practices in shell scripting along the way.
