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.

The Sapporo Municipal Subway (Sapporo-shiei-chikatetsu) is an underground rubber-tyred metro system in Sapporo, Hokkaido, operated by the Sapporo City Transportation Bureau.

The system consists of three lines: the green Namboku Line (North-South line), orange Tozai Line (East-West line), and blue Tōhō Line. The first, the Namboku Line, was opened in 1971 prior to the 1972 Winter Olympics. The Sapporo City Subway system operates out of two main hubs: Sapporo Station and Odori Station. Most areas of the city are within a reasonable walking distance or short bus ride from one of the subway stations.

The three lines all connect at Sapporo Station with the JR Hokkaido main lines. At Odori and Susukino stations, it connects to the streetcar (tram) above. Source: en.wikipedia.org
