About borg

BorgBackup (borg) is a deduplicating backup program designed for efficiency and security. It supports compression and authenticated encryption, making it suitable for daily backups where only changes are stored. The tool is particularly useful for backups to untrusted targets due to its strong encryption capabilities.

Borg splits files into variable-length chunks and stores only unique chunks, significantly reducing storage needs. This approach works across different machines and file systems, unaffected by file movements or modifications. The software is implemented with performance-critical code in C/Cython for speed and includes features like local caching and quick detection of unmodified files.

Key features

Space efficient storage through content-defined chunking and deduplication
Data encryption using 256-bit authenticated encryption (AES-OCB or chacha20-poly1305)
Optional obfuscation of file/chunk sizes to hinder fingerprinting attacks
Compression support with lz4, zstd, zlib, and lzma algorithms
Off-site backups via SSH with performance advantages over network file systems
Mountable backup archives as user-space file systems for easy access
Easy installation on multiple platforms including Linux, macOS, and FreeBSD
