Time Machine "not enough memory"
Time Machine says "not enough memory", even though it's been backing up this same computer for 2 years without a problem. Why suddenly did it not have enough memory?
Mac mini 2018 or later

Well aware of that. But Time Machine is supposed to delete the oldest backups when space is needed. I’m running a 2TB external drive as my Time Machine, and it’s done fine in the past.
Let's assume you mean HD space as opposed to memory. The TimeMachine backup HD needs to be 3-5 times larger than the one you're backing up.
