Post-Quantum Backups Land in openSUSE Factory with ZUPT

ZUPT, an open source backup, compression, and data protection utility, has officially been accepted into openSUSE Factory, bringing a new security-focused backup option to the openSUSE ecosystem. The project combines backup creation, compression, integrity verification, and encryption in a single tool, allowing users to package files and directories into compact archives that are easier to store, transfer, verify, and restore.

Security is one of ZUPT’s main technical highlights. In addition to AES-256-based encryption, the tool supports a hybrid cryptographic scheme based on ML-KEM-768 + X25519. This approach combines established public-key cryptography with a post-quantum key encapsulation mechanism designed to provide stronger protection against future cryptographic threats. For users handling long-lived or sensitive backups, this adds an additional layer of protection against so-called “harvest now, decrypt later” scenarios, in which encrypted data collected today could potentially be targeted by more powerful computing systems in the future. ZUPT also includes file integrity verification features to help detect corruption, modification, or unexpected changes in archived data.

ZUPT was also designed with performance in mind. The application uses multithreaded processing to take advantage of multiple CPU cores during backup, compression, and restore operations, reducing processing time on modern systems. It includes its own compression mechanism as well as commands for testing and validating archive contents. With its acceptance into openSUSE Factory, ZUPT becomes an officially integrated solution for users looking for a combination of backup, compression, integrity verification, encryption, and post-quantum data protection within the openSUSE ecosystem.
