I never had a backlog until I had kids. I shot and immediately developed because I wanted to see. However, I don't have the luxury now to disappear whenever I want to develop film anymore...so I'm expecting to have a backlog. I'm going to try to keep it to a minimum, though, by buying the Mod54 processor and a Paterson 3 roll drum after Christmas with reels so that I can handle 2 120 and 3 135 at a time, plus the 6 sheets of 4x5 at a time...and I'm working on a homemade solution for 5x7. I have the idea, I just have to see if I can get it made.
