I have a tendency to want to get backups and redundancy for my preps, that is, I don't want all my eggs in one basket if I can help it.
I have at least six ways to produce or store potable water (monolithic filters, calcium hypochlorite, Aquapods, water heater, bottled water, "boxed" water). Given how important water is, having lots of redundancy makes sense to me.
I have a Country Living mill, bought the spare parts and extra burrs for it.
I have a 4000-watt genny; bought a small 900-watt genny as an emergency backup to the emergency backup.
What do you deem so important that you have either stocked spares, identified alternative methods, or bought extras as backups?
