What was the rationale behind basically using a pi to just forward the files to your main PC? Wouldn't it be more efficient to just do everything on the main PC - using task scheduler or something?
I'm also concerned about putting all eggs in one basket. Ive experienced a shutdown ruining the formatting on a drive and losing everything on it. That, and the possibility of theft (PC is more attractive than a little hard drive) or water spilling on the comp and frying something, is what's preventing me from the simple option of just putting everything on the PC.
