KopiaUI

Kopia provides encrypted, compressed, and deduplicated backups that can be stored on any cloud service the user selects. It offers both a graphical desktop application and a command‑line interface, allowing creation of snapshots, definition of backup policies, and rapid restoration of files. The software runs on macOS, Windows, and Linux, and is designed to handle data ranging from personal laptops to larger server environments.

The desktop UI presents a straightforward workflow for configuring backups, while the CLI gives scriptable control for advanced users. Both interfaces support pluggable encryption and compression modules, ensuring that stored data remains secure and space‑efficient. Users can choose from a variety of cloud storage back‑ends, integrating the tool with existing cloud accounts.

Kopia is an open‑source project with a stable release status and an active user forum for support and discussion. Its architecture emphasizes speed and scalability, making it suitable for routine personal data protection as well as more demanding enterprise backup scenarios.
