Here is my current situation
LPR and "Back" clips I'm happy with. But around the front I don't want to reduce clip time to lower than 30 days

I am adding another 4PM cam with Audio, so I could add it to "Front 2" but I don't want it to go less than 30 days, and I think it might. How do you guys calculate it out?
I have 20+ 8TB SAS disks spare, so I could add an 8TB disk, but what should I move to where? (Yeah, my signature says I have 4 x 12, but I stole some for something else...)
