Some research projects of data storage that can last for thousands or even millions of years. By deployed I mean manufactured
Unless you want to carve large holes in granite, your best shot at the moment is something like the Arctic World Archive.
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.

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.
Giant letters on the face of the moon!

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.
