Its package-manager significance comes from being a modern Go backup system with both CLI and GUI workflows, installable as a single user-facing tool on macOS, Linux, and Windows. ### Project history The GitHub repository was created on 2015-12-19, while the public release stream visible in GitHub releases begins with v0.3.0 prereleases in 2019. The project settled into the same problem space as restic and BorgBackup: content-addressed, encrypted snapshot backups that can target local storage, NAS, and cloud object stores. Kopia's documentation and README emphasize user-controlled end-to-end encryption, compression, deduplication, and support for storage backends such as S3-compatible stores, Azure Blob Storage, Backblaze B2, Google Cloud Storage, WebDAV, SFTP, Rclone-backed locations, local disks, and Kopia's own repository server. ### Adoption history Kopia grew into a recognizable package-manager backup tool because it combined repository-format features package users expect from backup software with a straightforward CLI binary. Homebrew, Scoop, Nix, APK, and zypper packaging in the input data show adoption across both workstation and server-oriented ecosystems. GitHub repository metadata observed on 2026-07-01 reported 13,555 stars and 674 forks, which is substantial for a specialist backup utility and helps explain why it appears in multiple package indexes rather than only as a manual binary download. ### How it is used Operators use Kopia to create repositories, snapshot selected directories, restore files, and connect repositories to cloud, remote, or local storage. It is not an image-backup tool; the official README frames it around backing up directories and files that users choose. For package users, the important split is CLI versus GUI: the `kopia` command supports automation and server use, while the same project also offers a desktop-facing experience for less shell-heavy backup workflows. ### Why package nerds care Kopia matters to package nerds because it is a compact, cross-platform backup stack with encryption and deduplication built in, so one formula gives users a serious alternative to older backup systems without pulling in a large runtime. Its Go implementation, multi-backend storage model, and single-command installability make it fit neatly into Homebrew/Nix/Scoop-style package catalogs where users expect modern infrastructure tools to be portable and scriptable. ### Timeline - 2015-12-19: GitHub repository created. - 2019-05-10: v0.3.0 prerelease series appears in GitHub releases. - 2020-03-08: Kopia 0.5.0 was announced as an early milestone release in community-facing project discussion. - 2026-06-16: GitHub showed v0.23.1 as a release on the repository page. ### Related projects - Kopia sits near restic, BorgBackup, Duplicacy, and rclone in package-manager culture: tools for encrypted personal and server backups, deduplicated repositories, and cloud-backed storage workflows. - Rclone is also directly related because Kopia documentation lists Rclone-backed locations as a storage option, with Kopia managing and running Rclone for those backends. ### Sources - - - - ## Security Notes No matching local secret-handling manifest was found for kopia.
