How would I get my terminal to regurgitate the previous output text from past commands? Is this even possible?

I just ran a job that takes several hours, and I forgot to pipe that text into a text file. pseudocode: echo [previous text output] > OutputHistory.txt Additionally, I can't just "copy and paste" what was in my terminal because 1) the display omits important formatting characters like "\t", and 2, I may have closed the terminal window. Is this possible with any Unix commands?
