Every package kopia depends on, ranked by repo health score.
Kopia is an open-source backup tool that creates encrypted, compressed, and deduplicated snapshots of files and directories, storing them on any cloud or local storage of your choice. Rather than imaging entire disks, Kopia lets you selectively protect the files and directories that matter most, applying client-side end-to-end AES-256 encryption so that no storage provider — not even Kopia's own servers — can access your data.
Built in Go and available for Windows, macOS, and Linux, Kopia supports a wide range of storage backends including Amazon S3, Azure Blob Storage, Google Cloud Storage, Backblaze B2, WebDAV, SFTP, and Rclone-compatible services such as Dropbox, OneDrive, and Google Drive. It offers both a powerful CLI for scripting and automation and a native desktop GUI for visual snapshot management, making it accessible to power users and casual users alike.
At its core, Kopia's repository format combines content-addressed deduplication, Reed-Solomon error correction, and pluggable compression (LZ4, Zstandard) into a single verifiable archive. A dedicated Kopia Repository Server mode allows multiple machines to share a single encrypted repository, enabling centralized backup management for small teams and homelabs without requiring third-party services.
