This master’s thesis is focused on detailed analysis of possibilities of implementing a private cloud and secure data archiving for a long period of time using open-source tools. It describes the individual standards and processes of data preparation, as well as the OAIS reference model for long-term preservation. From the analyzed information, a complete design of the final solution is created, with a description of the functionality and the method of deployment in the environment of Docker containers. The design implementation and the main functionality of individual systems such as Archivematica or Nextcloud are thoroughly described and also the hardware requirements and cryptographic security were evaluated.
