Once the data has been acquired, it has to be stored. As a prerequisite, the necessary space has to be provided. Since masses of data are involved and high standards are being demanded, a very robust and capacious solution has to be installed. A trade off between high capacity, short access times, and low costs has to be found according to the resources and the goals of the initiative.
In Section 2.3.1 the basic trends and possibilities for media selection are presented. For such a project geared towards the long-term, the longevity of archival media is an important issue and will be discussed in Section 2.3.2. Not only the physical storage space needs to be provided, but also organising the data demands a careful design, which will be issued in Section 2.3.3.
