Wiith great effort we try to ensure the readability of the tapes in the long-term archive that have not been used for a longer time.
We have installed a monitoring that is continously reading the firmware diagnostic information of the tape drives. With this information we can evaluate the quality of the tape material and detect arising defects before they become a real problem.
For a detailed description of this feature you have to follow the link Data Storage at ZIB.
An increasingly important role belongs to long-term storage of irreplaceable data, such as results of measurements of physical experiments, digitized views of archaeological artifacts and documents. In addition to high own requirements for storage capacity, there is a use by external scientific institutes in the form of cooperations. For this purpose we give them virtual machines on powerful servers which have access to the data storage. Our work is an exact and securely reproducibility of the data as a stream of bits without examining the contents of the data. A continuous improvement of the underlying technology sometimes requires a migration of data. This is also done by us.
Beyond that we are working accordingly to the scientific tasks defined in the goals of the cooperation agreements.
