The universe is brutal on information. I'm looking for ways to preserve about an exabyte of information for a million years. I'm looking for answers rooted in reality without any lucky circumstances helping it along.
I'd prefer if there were minimal to no systems in place to maintain it.
I'm also hoping the information can be stored at maximum on a planetary scale, but hopefully much smaller.
Any ideas?
It should be relatively easy to extract the information as well.
