第2章 Preparing the backup node
Before you back up the undercloud or control plane nodes, prepare the backup node to accept the backup images.
2.1. Preparing the NFS server
ReaR can use multiple transport methods. Red Hat supports back up and restore with ReaR using NFS.
Install the NFS server on the backup node.
[root@backup ~]# dnf install -y nfs-utils
Add the NFS service to the firewall to ensure ports
111and2049are open. For example:[root@backup ~]# firewall-cmd --add-service=nfs [root@backup ~]# firewall-cmd --add-service=nfs --permanent
Enable the NFS server and start it.
[root@backup ~]# systemctl enable nfs-server [root@backup ~]# systemctl restart nfs-server
