That's kind of what I like about my setup. It is a shop but it's hosted on my home server which is using my own HDDs. The NSP/NSZ files are still there unless the HDDs fail or I delete them myself.Just remember that one day Nintendo may shut everything down for good. That's why I grab all my files immediately because you never know what the future holds. I have 1TB of switch games on my external HDD. But if you know how to set up your own shop that's good.
I just rather have my files on hand because I don't use internet on my CFW switch.
