The Howdy Glossary

BorgBackup, or Borg, is an open-source backup software designed for Unix-like operating systems that leverages content-defined chunking to minimize storage size by deduplicating data and enhancing post-backup verification processes. It encrypts data during transfer and storage with authenticated encryption, ensuring the security of backups even from service providers. Additionally, Borg efficiently manages file metadata and supports compression to optimize storage resources.

Created by Thomas Waldmann, BorgBackup serves as a robust tool for secure and efficient backups on Unix-like systems. Its unique features include content-defined chunking for effective deduplication, encryption of data in transit and at rest using authenticated encryption methods, and meticulous handling of file metadata like permissions and ownership information. Compression support further aids in minimizing storage usage while maintaining high performance.

Competitors such as Duplicity, rsync, and Restic offer distinct strengths like bandwidth-efficient encrypted backups (Duplicity), fast file synchronization (rsync), and secure backup solutions (Restic). However, Borg sets itself apart through its comprehensive suite of features focusing on deduplication, robust encryption, metadata management, and compression capabilities. These attributes ensure that users get a reliable, secure backup tool optimized for Unix-like environments while addressing both personal and professional needs efficiently.
