Some research projects of data storage that can last for thousands or even millions of years. By deployed I mean manufactured
Thousands is not that difficult. Paper lasts for thousands of years under the right conditions. Millions is a whole different game. That’s significantly longer than humanity has existed It’s not just about the material, it’s also about not losing the ability to read the contents. There are texts less than 5000 years old whoch we cannot read anymore.
Just make it binary representations of 3D, engraved in stone.

Paper lasts for thousands of years under the right conditions.
How do you maintain the right conditions for thousands of years?
Caves.
Pyramids too maybe. Disks in a lead or titanium chest in a pyramid.
Yes. It’s called a stone tablet.

Silica is expected to survive for thousands of years in nearly any temperature, humidity, and chemical environment
Thousands of years is very different than 1 million years.
There’s nothing that can stick around 1 million years.
The 3rd installment of the 3 body problem touches on this subject.
nothing that can stick around 1 million years

Explain
Even things that seem like they won’t ever change don’t last. Erosion, tectonic plate movement, natural decay of atoms.
Even giant letters written inside of a mountain won’t last.
Best you can do is create a simple structure that takes intelligence to create with the only purpose being to show that you once existed.
Rocks exist that are billions of years old, so clearly some things can survive for longer than a million years. And if we don’t restrict ourselves to the Earth, something in a high heliocentric orbit could last many billions or perhaps even trillions of years.
True but rocks change over time constantly.
Giant letters on the face of the moon!
