I replicate my entire filesystem to a local NAS every 10 minutes using zrepl. This has already saved my bacon once when a WD_BLACK SN850 suddenly died on me [1]. It's also recovered code from some classic git blunders. It shouldn't be possible any more to lose data to user error or single device failure. We have the technology.
