🔐 Data Backup Scheme Implementation in Linux

📌 Overview

This project demonstrates the design and implementation of a reliable and automated backup scheme in Linux.
It leverages:

• Rsync → for efficient file synchronization and backups
• Cron → for scheduling periodic backups
• SSH → for secure data transfer

The solution ensures data integrity, availability, and resilience against accidental loss or corruption.
It was developed as part of an academic project submitted to L&T EduTech.

🎯 Project Objectives

• Develop a functional backup scheme for Linux in a controlled environment.
• Demonstrate rsync-based backups for directories/files.
• Automate backups with cron jobs.
• Test reliability, error handling, and recovery.
• Document the setup, findings, and recommendations.

⚙️ Methodology

1. Environment Setup

   • VirtualBox / VMware for test environment
   • Linux (CentOS) as server and client
   • Network-attached storage (NAS) for backup

2. Implementation

   • Rsync for incremental backups
   • Cron for scheduling daily/weekly/monthly jobs
   • SSH for secure transfers

3. Testing

   • Full, incremental, and partial restore
   • Error handling (storage, permission, connectivity issues)
   • Verification of data integrity and completeness

🖥️ Installation & Usage

1. Clone this repository:

   git clone https://github.com/eTac01/linux-backup-solution.git
   cd linux-backup-solution

2. Configure backup.sh:

   Edit the script with your source, destination, and server IP.

3. Run a Manual Backup:
      bash src/backup.sh

4. Schedule with Cron:

   Open crontab:

      crontab -e


      Example (daily at 1 AM):

      0 1 * * * bash /path/to/backup.sh

📊 Findings

   -> Rsync transfers completed within allocated time.

   -> Backups remained unaffected even after deletion from the source.

   -> Scheduling worked smoothly using cron jobs.

   -> Scalability was validated using multiple Linux systems.

⚠️ Security Considerations

   -> Potential exploitation risks:

   -> Unauthorized access

   -> MITM attacks during transfer

   -> Injection of malicious code into backups

✅ Recommendations

   -> Use AES-256 encryption for backup data.

   -> Implement role-based access control & MFA.

   -> Regularly patch backup systems.

   -> Segment networks with firewalls & IDS/IPS.

   -> Conduct regular vulnerability assessments.
