The best way to preserve something is not with technology or any particular storage medium.

The only way to ensure something is preserved is for there to be living humans who care about the thing enough to put forth the effort to preserve it.

Information that is stored in very fragile old formats is well preserved because there are living humans who are putting forth the effort. Information that nobody cares about, but is stored very securely, will be culled eventually as even libraries and archives have limited capacity.

If you want your personal website to be preserved, the best thing you can do is make it so good that your children, or someone else, cares about it enough to keep it.
