Glacier Deep Archive is exactly what you want for this, that would be something like $11/month ongoing, then about $90/TB in the event of retrieval download. Works well except for tiny (<150KB) files. Note that there is Glacier and Glacier Deep Archive. The latter is cheaper but longer minimum storage periods. You can use it as a life cycle rule.
