A backup to a backup is a good plan. Our house has baseboard electric as primary heat, which became the secondary source to the heat from the wood stove we installed in 1990, wood since then being the primary heat. Electric is quite dependable in our area, but still concerned, especially if we leave home for a week or two in winter and have electricity interrupted. So we also installed a direct vent 35,000 btu LP wall cabinet furnace with a 120 gallon LP tank, and millivolt pilot light thermostat, as the emergency backup when we're gone. No electricity needed to operate. That is sufficient to keep the house from freezing up, and the LP is good for 1-2 weeks.
But as for "really snowed in and can't get to wood shed, or just too damm sick or any other irrational reason," we have about 1/3 cord of wood kept on the back porch, replenished as needed from the wood shed, and a wood box in the living room that holds sufficient wood for about 5 days supply in the coldest weather (-30 to -40F). Those two together will handle the irrational reasons and keep the wood stove fired.
But if the glass breaks on the stove? 26 years of burning wood and never thought about that ... and will continue to not think about that.
