Audiovisual Collections of Musical Folklore in Wartime: a Project of Server Infrastructure for Digital Data Storage

The article presents the experience of developing and implementing a server infrastructure for storing digital audiovisual collections of Ukrainian musical folklore. Particular attention is given to the technical aspects of preservation, backup, and ensuring data accessibility during wartime. The proposed system is based on a mobile architecture that enables quick relocation and recovery of servers without administrator intervention. The implementation of the system relies on the use of the ZFS file system to ensure data reliability and integrity, as well as RAIDZ technology to protect against hardware failures. A key role is played by the application of the 3-2-1 backup principle, which involves creating multiple copies of data on different storage media, including in the cloud environment. For remote data access, the WireGuard protocol is used, providing secure VPN connections between users and servers. The proposed server infrastructure addresses key challenges faced by Ukrainian ethnomusicologists and cultural institutions in working with digital archives: storing large volumes of audiovisual data, organizing automated backups, and enabling prompt access to collections. A distinctive feature of the system is its scalability, allowing it to be used both locally and as part of a nationwide digital repository. The proposed approaches were tested using materials from the Laboratory of Ethnomusicology at the National Music Academy and private recordings of its staff. Practical results demonstrate the effectiveness of the developed infrastructure in preserving cultural heritage, especially under the devastating threats posed by war.
