Ipfs private network, file access issues

In ipfs private network, if an ipfs node uploads a file and the node disconnects, how does the other node connected to it access the file he uploaded previously?

IPFS doesn’t automatically replicate content. If you add files to your IPFS node, they won’t be uploaded to the network in general. Instead, your node will:

  1. Announce that it has the files to the network.
  2. Give the files to any node that requests them.
