"If there's a moral to the story it is look after those backups" Not really.
What research organizations should do is make
a) The raw data from the experiment
b) The data acquisition model (IE what those numbers are from, what resolution, sample rate they are from)
c) The instrument specs.
On accessible servers. The data should be secure from being changed but not downloaded.
As others have noted the datasets are (by modern standards) not that big and as the story notes it seems some of them have never had a detailed review.
IOW Fresh meat to the army of Asto/fusion/geo physics PhD's candidates out there looking for a topic, glory and possibly a shot at a Nobel.
I bet there's a lot more to be mined from those data sets.
