Additional Jury Comments Highly dependent on who is looking after the offline media but more difficult over time. There is a lack of granularity in the definition of media so only generic advice is possible such as "make sure you're moving your data to new forms of storage every 5 -10 years". It would be possible to split into different storage media (maybe 100 items long). |
