I setup a command line IPFS node on Linux. It is working, I got through the QuickStart guide. I can add content and access it from my own or a public gateway.
The reason I wanted to set this up is mostly to pin content that is already on IPFS but I want to ensure it never disappears in case the original node that added it goes offline.
What is the best method to do that? Do I just add it again? Or is there a command to pin the content already hosted elsewhere on the network?
