Greetings @BadJawn,
Welcome to Overgrow,
Good Question, but long term storage of a cut clone probably isn’t your answer. Long term storage of a cut clone is experimental and still an iffy proposition.
Cut a fresh clone, root it properly, transplant it and make a bonsai mother plant.
Then you can “Reliably” take additional cuts as needed.
“if you actually need the genetics to survive…”
Do it like they do on the Discovery Channel… Grow a male and a fem and make seeds.
