# Borg BorgBackup (Borg) is a deduplicating backup archiver that provides space-efficient storage of backups through content-defined chunking and data deduplication, combined with authenticated encryption for security. It supports multiple compression algorithms (lz4, zstd, zlib, lzma), allows mounting backups as filesystems via FUSE for easy browsing and restoration, and runs on Linux, macOS, and BSD. Borg is BSD-licensed free software backed by an active open-source community. ## References - Official website: https://www.borgbackup.org/ - Documentation: https://borgbackup.readthedocs.io - Source code: https://github.com/borgbackup/borg
