Its own README frames it as a CLI Time Machine for ZFS, btrfs, NILFS2, Time Machine, and Restic-style storage. ### Project history The GitHub repository was created in March 2022, and crates.io records the httm crate beginning in May 2022. The project grew around a Unix idea: expose snapshot history at the file level, rather than treating snapshots mainly as dataset-wide rollback machinery. ### Adoption history httm reached package-manager users through crates.io and later through system package channels represented in the input metadata, including Homebrew, Alpine, and Nix. GitHub topics and README examples place its audience among ZFS, btrfs, FreeBSD, Linux, homelab, and shell users. ### How it is used Users run httm against one or more paths to print unique versions by size and modification time, browse versions interactively, output JSON, find deleted files in snapshots, and work with alternate stores such as Time Machine or mounted Restic repositories. ### Why package nerds care The package is interesting because it turns filesystem snapshot plumbing into a small composable CLI. The related ounce and bowie tools show the same package-nerd pattern: wrap a focused executable into shell workflows for dynamic snapshots and diffing historical file versions. ### Timeline - 2022: The kimono-koans/httm repository was created on GitHub. - 2022: The httm crate appeared on crates.io. - 2022: The author described httm's inspiration in file-level ZFS and btrfs snapshot workflows. - 2024: Release notes included macOS local snapshot support in the 0.35 line. ### Related projects - Related tools include ZFS and btrfs snapshot tooling, NILFS2, Apple Time Machine, Restic, and httm-adjacent wrappers such as ounce and bowie. ### Sources - Official GitHub README, author project article, crates.io metadata, and GitHub release metadata. ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** httm - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Conflicts With:** nicotine-plus - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - httm: normalized package name match | nixpkgs package indexes: pkgs/by-name/ht/httm/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - apk - httm - 0.49.9-r0: normalized package name match | Alpine Linux edge package indexes: httm from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Interactive, file-level Time Machine-like tool for ZFS/btrfs | https://github.com/kimono-koans/httm - apk - httm-doc - 0.49.9-r0: normalized package name match | Alpine Linux edge package indexes: httm-doc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Interactive, file-level Time Machine-like tool for ZFS/btrfs (documentation) | https://github.com/kimono-koans/httm ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Archive and compression packages](https://www.automicvault.com/pkg/archive-compression-tools/) - Matched archive or compression metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [rsnapshot](https://www.automicvault.com/pkg/brew/rsnapshot/) - Shares av.db curated category or tags: backup, cli, filesystem, snapshots, system. - [znapzend](https://www.automicvault.com/pkg/brew/znapzend/) - Shares av.db curated category or tags: backup, cli, snapshots, system, zfs. - [zrepl](https://www.automicvault.com/pkg/brew/zrepl/) - Shares av.db curated category or tags: backup, cli, snapshots, system, zfs. - [dar](https://www.automicvault.com/pkg/brew/dar/) - Shares av.db curated category or tags: backup, cli, filesystem, system. - [kopia](https://www.automicvault.com/pkg/brew/kopia/) - Shares av.db curated category or tags: backup, cli, snapshots, system. - [timedog](https://www.automicvault.com/pkg/brew/timedog/) - Shares av.db curated category or tags: backup, cli, filesystem, system. - [afio](https://www.automicvault.com/pkg/brew/afio/) - Shares av.db curated category or tags: backup, cli, system. - [bacula-fd](https://www.automicvault.com/pkg/brew/bacula-fd/) - Shares av.db curated category or tags: backup, cli, system. - [rsync-time-backup](https://www.automicvault.com/pkg/brew/rsync-time-backup/) - Local package facts share a topical domain.
