the website says “Each network node stores only content it is interested in”, and i didn´t find any info how this can be configured or how this “selecting” is working in general. would be nice to have some infos about this.
Basically it works by nothing being stored automatically by others.
When you first connect to the network with a fresh IPFS node, you’ll have only a small set of “starter” files, like basic instructions and similar.
Nothing gets added to your node automatically, and the same goes for when you add content. It doesn’t automatically distribute content to other nodes. Other nodes needs to run
ipfs pin add $HASH to start resharing content. Also, when doing
ipfs get $HASH (or
cat) it also helps resharing the content but only until you run garbage collection.
Ahhhhhhh that makes totally sense now, i was thinking, omg, when I start a node I get terabytes of data I don’t want thanks for clarification!
