I am new to IPFS, I initially understood that if I have an IPFS node and that I write a file to it that if my node disappears that my file will not (a bit like a distributed RAID 5 system) : “every file on IPFS can be hosted in many different places, yet accessed from the same address. If one computer hosting the file goes offline, the network will just retrieve the file from another computer.”
But while reading around it seems that this is not the case somehow, my files are not duplicated : “IPFS removes duplications across the network”. I also read that if nobody requests my files that they stay on my node (meaning my files can disappear if my node goes down). In case another user requests a file and it is copied to another node, it seems to contradict the fact that duplicates are removed.
I am trying to store publicly available files that should stay publicly available, even if my node disappears.
I think there is something I am missing here, can someone please explain it to me?
