I was trying to analyze the original request, which seems to be something of the following set:
- The goal is to archive a large amount of (presumably public) data on a community run globally sharded or distributed storage. - Can Ceph be used for this? Seems no, at least not in a sense of running lots of OSDs at different locations by different people loosely coupled into one global public data repo. Perhaps, there are some other ideas from people who have done this kind of thing. - Are there restrictions on obtaining the data? If it's public and accessible now, it should be able to be copied. If not, what are the restrictions on obtaining and copying the data? - Organization: how will the storage and maintenance of data be organized (and funded)? A foundation, a SETI-at-home like network, a blockchain (to preserve data veracity)? - Legal support? -- Alex Gorbachev On Tue, Apr 8, 2025 at 9:41 AM Anthony D'Atri <a...@dreamsnake.net> wrote: > The intent is the US administration’s assault against science, Linas > doesn’t *want* to do it, he wants to preserve for the hope of a better > future. > > > > On Apr 8, 2025, at 9:28 AM, Alex Gorbachev <a...@iss-integration.com> > wrote: > > > > Hi Linas, > > > > Is the intent of purging of this data mainly due to just cost concerns? > If > > the goal is purely preservation of data, the likely cheapest and least > > maintenance intensive way of doing this is a large scale tape archive. > > Such archives (purely based on a google search) exist at LLNL and OU, and > > there is a TAPAS service from SpectraLogic. > > > > I would imagine questions would arise about custody of the data, legal > > implications etc. The easiest is for the organization already hosting > the > > data to just preserve it by archiving, and thereby claim a significant > cost > > reduction. > > > > -- > > Alex Gorbachev > > > > > > > > > > On Sun, Apr 6, 2025 at 11:08 PM Linas Vepstas <linasveps...@gmail.com> > > wrote: > > > >> OK what you will read below might sound insane but I am obliged to ask. > >> > >> There are 275 petabytes of NIH data at risk of being deleted.
