软件包摘要
Easy and efficient encrypted backups
历史
项目历史与用法
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.
项目历史
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.
采用历史
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.
使用方式
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.
为什么软件包爱好者会关心
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.
