This is what I do, maybe not optimized to the best but if you looked at my factories they are not optimized but they will never clog because of by products.
I tried using the waste yellow stuff (I’m not at a computer lol) from making uranium cells to process the nuclear by product but it kept getting clogged and I ended up setting up a package and sinking it for full reliability.
This was all my first blind playthrough. I learned a lot but there is something to be said for reliability
You missed the (and doing it properly) part. Could you do it on his setup? sure. Could you do it on your setup recommendations? Sure. Could you do it on a little raspberry pi? Probably. A industry standard best practice for backup is 3-2-1. Do all companies follow industry best practices? Heavens no. Redundancy is great, it may save you from calling someone at triple rates for after hours support only to find your one 48 port switch failed. It’s all about what risk you are willing to take on any of this.
