I will not say about the global level. But for me personally, yes, of course. Under sad circumstances, I recently got a 3TB external hard drive. For me it was more than sad. A collection of music, collected and sorted by me over the years, a bunch of books (on the Internet their names are not always there, not like electronic versions). A bunch of scientific articles downloaded at the university (now you can get them either by an expensive subscription or not at all). A lot of materials for Photoshop, including paid ones. Not to mention some personal materials (photos, projects, important documents, etc.). Films, of course, are not so important to me, but it's also a shame: with the development of anti-piracy sentiments, it becomes very difficult to search for some.
With the recovery of the problem. and there is a high probability that a lot of things will disappear without a trace.
Well, let's say the recent leakage of data on offshores of high-ranking officials from different countries. Or the current WADA data. In general, everything related to the disclosure of "skeletons in closets" can be called invaluable data. There are many examples.
