I also have a system that pumps about every 10 minutes. My backup is water powered, which assumes you have "city water" rather than a well/pump. Works beautifully. Mine pumps one gallon of sump water for every 7 gallons of house water, which is a lot of water, but better than a flooded basement. My experience with pump lifetime is about 2-3 years. I now pull mine about every year, install a standby, and have the pump professionally cleaned/refurbished. For extended power outages I have access to a generator.
