history

Project history and usage

Kopia is a cross-platform open-source backup and restore tool built around encrypted, deduplicated, compressed snapshots. 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.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
