Kopia

Kopia is a backup utility designed for Linux systems to manage data preservation and recovery operations. It creates encrypted snapshots of user-specified directories and stores them in various storage backends, including local file systems and cloud object storage services. The software processes data by dividing files into variable-length chunks, applying deduplication to reduce storage consumption, and compressing the output before transmission. Users interact with the utility through a command-line interface or a web-based dashboard for scheduling backup policies, monitoring snapshot history, and restoring files. Licensed under the Apache-2.0, the program operates locally and allows users to retain complete control over their encryption keys and destination repositories.
