## Historique du projet et usages

Bupstash is a Rust backup tool focused on encrypted, deduplicated, incremental backups with client-side encryption and remote repositories over SSH. It occupies the same practical space as modern deduplicating backup CLIs but makes encrypted metadata, queryable tags, and offline decryption keys central features.

### Historique du projet

The public repository was created in August 2020, and Andrew Chambers introduced Bupstash publicly in November 2020. The README and website describe a beta-stage tool designed for efficient deduplication, strong privacy, offline decryption keys, encrypted tag search, slow-network performance, restricted remote access controls, and low memory use.

The technical overview explains the implementation model: arbitrary data streams are chunked, deduplicated, encrypted client side, stored locally or remotely, and indexed with encrypted metadata. The design uses keyed hashes for addressing chunks, a rolling hash for split points, libsodium cryptography, hash trees for large streams, and client-side metadata sync for queries.

### Historique d'adoption

Bupstash gained enough command-line backup interest to be packaged across several ecosystems; the input metadata records apk, Homebrew, MacPorts, Nix, and Arch packages. Its adoption is narrower than older tools such as bup or Borg, but it has a clear niche among users who want encrypted deduplication without operating a large backup service.

### Modes d'utilisation

Typical usage starts by initializing a repository, creating a key file, setting `BUPSTASH_REPOSITORY` and `BUPSTASH_KEY`, then using commands such as `put`, `list`, `get`, `diff`, `restore`, `rm`, and `gc`. Bupstash can store file trees, tar streams, and command output, and its `put` command benefits from avoiding already-sent file content.

### Pourquoi les passionnés de paquets s'y intéressent

Bupstash is significant because it shows the post-Borg/Restic generation of backup tooling: single-binary CLI distribution, strong default encryption, SSH-friendly self-hosting, and deduplication that still works with encrypted data. Its key-separation model is especially attractive for package nerds thinking about ransomware-resistant unattended backups.

### Chronologie

- 2020-08: Public GitHub repository created.
- 2020-11-20: Introductory Bupstash blog post published.
- 2021: Project documentation covered garbage collection, encrypted metadata, and operational guides.
- 2026: Homebrew metadata lists Bupstash as a packaged encrypted-backup CLI.

### Related projects

- Bupstash is related to bup by name and backup focus, and to Borg, Restic, Attic, Tarsnap, Duplicity, and rdiff-backup as part of the wider deduplicating and encrypted backup-tool family.
