Creating a 3 - 2 - 1  archive

Extend the 3-2-1 rule for archiving while maintaining data control and leverage LTFS Tape Storage. Take advantage of technology and media break.

With Nodeum, we established secure S3 to Tape long-term archiving. Achieved the goal of backing up university data in a neutral format (LTFS) on tape.

With about 14,000 students and 2,933 staff members and 2,926 in the medical care sector,  the University of Rostock offers fascinating perspectives into nearly all scientific fields.

In today's digital age, it's essential to extend the 3-2-1 rule for archiving while still maintaining complete data control. And that's where LTFS Tape Storage comes into play, offering an innovative solution to leverage the power of technology while embracing the concept of a media break.

By extending the 3-2-1 rule, valuable data remains secure and protected. This rule dictates that at least three copies of your data are stored on two different types of media, with one copy stored offsite. 


But what sets LTFS Tape Storage apart from other archiving solutions? It's the perfect combination of cutting-edge technology and the concept of a media break. With LTFS Tape Storage, you can seamlessly store and access your data on tape cartridges, providing a reliable and secure environment for long-term preservation.




  • The IT and media center (ITMZ) of the University of Rostock, in cooperation with the university library, is experiencing a constantly growing need from users for long-term digital archiving of research and library data.
  • ITMZ needs to fulfill new requirements in the archiving processes. In the future, for certain archives, it could be necessary not only to create a media break, but even to implement external offline archiving (cloud or colocation) of storage media.
Technology and Media Break


The University of Rostock, the team from the IT and media center, has created the infrastructural basis for the security of university data in close cooperation with our partners. Secure data transfer and format-neutral long-term archiving were organized. The goal of backing up the data generated by the university in S3 format in a neutral format (LTFS) on another technology (tape) and thus carrying out and optimizing data storage independent of manufacturer and technology was realized.


Copies are kept for data recovery in case of data loss. Further application scenarios for the data mover are already emerging in the coming years.

With the data mover software NODEUM, a solution has been found that can cover almost all conceivable working methods and needs of the archive user and at the same time provides a transparent access layer for the user in the form of the S3 protocol. Workflows that were previously impossible to implement can now be implemented.

“ The collaboration in the project is very cooperative.   AKQUINET involves the  manufacturers in every phase of the project right from the start. In this way, the project duration is constantly optimized and friction losses are kept as low as possible. Now that the complex tests of the hardware and software functionalities have been  completed, we are starting to produce and customize/expand the application.  NODEUM offers us incredible flexibility in the workflows to be mapped. ”

“ We consider it important, in addition to the optimized data structure within and between our heterogeneous system landscapes, to implement more security and an additional media break to protect our data as part of our data storage mechanisms. The use of the convenient and technically mature data mover NODEUM® ensures us efficiency and data security through the individual linking of our data sources, also via APIs and taking into account all role and authorization models. ”
