Look at the google books project. That got shutdown real hard due to copyright issues and litigation after they invested a ton of money in digitizing some of the most valuable library collections in the world.

I wonder if that's actually feasible for this application. Microdots managed about 32MiB / square centimeter (from the "you could fit the Bible 50 times in a square inch") measure. That's a completely arbitrary density to achieve, since it was photographs which were enlarged and shrunk, and you could hypothetically use any encoding for your gold etchings, and it also leaves out the question of "how fine can you etch…
Assuming you can cut the etching down to 1m squares and stack them on top of one another that should be no problem at all. Assuming each layer is 1.2mm thick (same as a CD) that's a volume of 1m x 1m x .390m, it would fit easily in a payload fairing of any rocket that can get it into orbit.
(Which isn't necessarily impossible, but still a lot, especially for an interstellar probe.)
Related: Looking at harddisk cost per terabyte, quite often extern drives are cheaper than internal ones. For example right now in Germany I can get a WD 8TB USB 3.0 drive for 135€ but the cheapest internal 8TB drive costs 169€. Any idea why? It's puzzling.

In large ZFS arrays, many people are using them with great success, at no greater or lesser annual failure rate than the expensive enterprise hard drives.

The volume isn't a real problem, but nearly half a cubic meter of gold should also have a mass of ~7500 kilograms. You're also looking at a cost of ~$350 million, US. (Which isn't necessarily impossible , but still a lot , especially for an interstellar probe.)
That puts it in the realm of the Voyager probes for total cost.

one of the next interplanetary or Interstellar Probe should carry a copy of the sci-hub torrent in some kind of permanent storage
This is an extremely important effort. The LibGen archive contains around 32 TBs of books (by far the most common being scientific books and textbooks, with a healthy dose of non-STEM). The SciMag archive, backing up Sci-Hub, clocks in at around 67 TBs [0]. This is invaluable data that should not be lost. If you want to contribute, here's a few ways to do so. If you wish to donate bandwidth or storage, I personally k…

In my experience ipfs doesn't actually work. I'd love to be proven wrong, but the reason why nobody uses ipfs even when it seems like a great fit is bect it's not really usable.
This is my experience as well. In theory, IPFS is exactly the right thing for LibGen, but in practice I consider it unusable.
The new architecture of pirate sites, what I call the Hydra architecture, seems pretty interesting to me. There isn't a single site hosting the content, but a group of mirrors freely exchanging data between one another. In case some of them go down, the other ones still remain and new ones can appear, copying data from the remaining mirrors. This is like a hydra that grows two heads every time you chop one off. It's…
Single decentralized service, providing access to all content, national and international, free of DRM, for all platforms, for a proper, fair, and non-monopolist price.
That will pull all the users who are willing to pay for content over to the paid service, and those who remained were not willing to pay regardless of what you did anyhow.
