Blockages are often caused by soil settlement, misaligned joints, tree roots, pipe collapse, grease buildup, or by placing items in your system that should not be flushed down a drain

Yes. There's a common device called a Backflow Preventer (BFP) that can be installed in your plumbing system by a licensed plumber. A BFP can be manual or automatic; it can effectively shut off the home or business from the street sewer system during extreme sewage backups. Please note that if the BFP is closed, or put into action, you must not use the toilet, sink, shower, washer, dishwasher, or any appliance that discharges wastewater. If you have a BFP installed, be sure to inspect it regularly.
