Time Machine and Software update not performing correctly

My Time Machine keeps on failing on backup and I can't update the operating system to the new software update 15.8.1. What steps do I need to do in order to get things working again?

Fix whatever is wrong with Time Machine first, then we can discuss updating macOS.
