3.2. Creating the configuration files

Create the ReaR configuration file:

[root@controller-x ~]# mkdir -p /etc/rear
[root@controller-x ~]# tee -a "/etc/rear/local.conf" > /dev/null <<'EOF'
OUTPUT=ISO
OUTPUT_URL=nfs://<ip-addr>/ctl_plane_backups
ISO_PREFIX=<SERVER_NAME-X>
BACKUP=NETFS
BACKUP_PROG_COMPRESS_OPTIONS=( --gzip )
BACKUP_PROG_COMPRESS_SUFFIX=".gz"
BACKUP_PROG_EXCLUDE=( '/tmp/*' '/data/*' )
BACKUP_URL=nfs://<ip-addr>/ctl_plane_backups
BACKUP_PROG_EXCLUDE=("${BACKUP_PROG_EXCLUDE[@]}" '/media' '/var/tmp' '/var/crash')
BACKUP_PROG_OPTIONS+=( --anchored --xattrs-include='*.*' --xattrs )
EOF

Replace <SERVER_NAME-X> with the hostname of the node. For example, if the node hostname is controller-0, replace <SERVER_NAME-X> with controller-0. Replace <ip-addr> with the IP address of the backup node running the NFS server configured in 2章Preparing the backup node.

Create the rescue.conf file:

[root@controller-x ~]# tee  -a "/etc/rear/rescue.conf" > /dev/null <<'EOF'
BACKUP_PROG_OPTIONS+=( --anchored --xattrs-include='*.*' --xattrs )
EOF
