This project demonstrates practical Linux administration skills by automating common system administrator tasks using shell scripts.

The automation includes:

• Automated application backups
• Linux user management
• File permission configuration
• System health monitoring
• Administrative activity logging
• Scheduled backup execution

✨ Key Features

1. Automated Backup System

• Creates compressed backup archives using tar
• Generates timestamp-based backup filenames
• Stores backup files in the configured backup storage
• Maintains backup logs
• Supports scheduled execution using Cron

2. User Management Automation

• Automates common Linux user-related operations
• Reduces repetitive manual administration tasks
• Uses Linux command-line utilities for user management

3. Permission Management

• Automatically configures required file permissions
• Helps maintain appropriate access to files and directories
• Demonstrates practical Linux ownership and permission management

4. System Health Monitoring

• Collects system information
• Generates system health reports
• Maintains monitoring logs
• Provides basic visibility into system status
