LazBackup: Cross-Platform Incremental Backup Program

LazBackup is an open-source software application designed to simplify and automate backup operations on Windows, macOS, and Linux operating systems. Developed using Lazarus, the application leverages the RAR compression engine to perform efficient and secure incremental backups.

Key Features

  1. Incremental Backup: Using RAR's -u parameter, LazBackup identifies and archives only those files that have been modified or added since the last backup. This process significantly reduces execution time and disk space usage.

  2. Automation and Scheduling: The software includes a scheduling module that allows users to set up automatic backups at a daily, weekly, or monthly frequency at a predefined time.

  3. Advanced File Management: Users can define lists of folders to include in the backup and specify file extensions to exclude (e.g., temporary files or files potentially infected by ransomware).

  4. Execution Modes:

  1. Tray Mode: The application supports launching in tray mode (/tray), operating in the background without a visible window.
  1. Configuration Loading: Backup configurations can be saved and loaded automatically upon application startup using the /load parameter.
  1. Security and Compression:
  1. Encryption: Archives can be protected with a password to ensure data confidentiality.
  1. Compression Levels: The user can choose from various compression levels to balance execution speed with the final archive size.

License and Requirements LazBackup is distributed under the Mozilla Public License (MPL).

For its operation, the software requires a separate installation of the RAR or WinRAR compression program on the system in use.
