I think that's a terrific question, which I haven't fully solved myself.

At the moment, I try to take advantage of free cloud storage options as much as possible. For example, all my step charts are stored on GitLab in a repository. I have separate repositories for code I've written, pieces of text, my website etc. I post most of my videos on YouTube or Google Photos, hoping that they won't get deleted someday...

All my credentials are stored in a password manager, and I plan of giving the access codes to the vault in my will. That way, my "successors" will have access to everything, even unlisted cloud content.
