Backup.c (WIP)

Overview

Backup.c is a robust and user-friendly utility designed to back up files and directories to an external storage device, such as a USB drive. With a focus on simplicity and functionality, this tool provides a seamless way to secure your data on Linux-based systems.

• Core Feature: Backup to external storage devices (e.g., USB drives).
• Development Duration: November 12 - November 24, 2024.
• License: GNU Affero General Public License v3.0.
• GitHub Repository: Backup.c

Features

1. Backup Functionality

• Backs up a source directory to a target location.
• Automatically creates a timestamped folder (e.g., Backup YYYY-MM-DD HH-MM-SS) in the target directory for better organization.
• Recursively copies files and directories while maintaining permissions and structure.

2. Custom Target Directory

• Allows specifying a custom target directory using the -t command-line option:

  ./backup -t /custom/target /path/to/source

• Saves the specified directory as the new default for future backups.

3. Enhanced Aesthetics

• Includes visual and functional details, such as random delays and color-coded debug logs, to enhance the user experience.
• Outputs informative messages and warnings for better transparency.

Installation

Prerequisites

• A Linux-based operating system (e.g., Raspberry Pi OS or other Unix-like systems).
• A C compiler (e.g., gcc).

Compilation

Compile the source code with the following command:

gcc -o backup backup.c

Usage

Run the program as follows:

./backup [OPTIONS] SOURCE_DIR

Options

• -t TARGET_DIR: Specifies a custom target directory for backups. Saves this directory as the new default.

Example

Backup the /home/user/Documents directory to the default target:

./backup /home/user/Documents

Specify a custom target directory:

./backup -t /mnt/usb /home/user/Documents

Design Highlights

Default Target Directory

The program reads the default backup directory from a configuration file located in the user's home directory (e.g., ~/.config/backup_tool.conf). If no configuration exists, the default directory is /media/pi/piBackup.

Timestamped Directories

Each backup is stored in a uniquely named folder based on the current date and time, ensuring backups remain organized and traceable.

Error Handling

The program validates directories, handles unexpected conditions, and provides detailed error messages for troubleshooting.

Future Improvements

• Extend compatibility to other Linux distributions by dynamically detecting the system's default external storage path.
• Install the program globally with root privileges for execution without ./ and from any directory.
• Add features like a progress bar or dramatic warning displays for enhanced interactivity.

Why It Was Built

• 60%: Because it seemed cool.
• 40%: For project submission.
• 15%: To manage GitHub contributions.
• 5%: Out of necessity.
