Air-gaped backups are electronically disconnected once they complete. See Mag Tape storage.

I'm a backup guy. A common way to get what you described is this unloved technology called "tape". THey are generally stored offsite, often in a secured facility or vault.

Modern backup devices are supposed to have hard-coded protections against deleting data marked read-only, but if you don't trust the hard-coding, tapes are a way to be sure.
