Explanation

Before restoring an Expressway cluster from a backup, you must first remove each peer from the cluster. This is necessary because cluster members synchronize configuration with each other in real time. If you restore a backup to a node while it is still part of a cluster, the restored configuration would immediately conflict with or be overwritten by data from the other peers. By removing each peer from the cluster first, you ensure each node is restored independently using its own node-specific backup. After all peers are individually restored, they can be re-added to rebuild the cluster cleanly.
