FYI, fire safes aren’t necessarily waterproof. They’ll protect your documents from the fire but not the firefighters’ water, or the drop through the burned out floor to the basement. Mine, for example, requires an additional treatment to be waterproof. Something to keep in mind if you haven’t already.

(I keep my backups in three places: local drives, safe deposit box rotated quarterly, and BackBlaze. I’ve only ever needed the first, but I feel safer knowing I have the other two.)
