4.4. Backing Up and Rest oring t he luci Configurat ion
You can use the following procedure to make a backup of the lu ci database, which is stored in the
/var/lib/luci/var/Data.fs file. This is not the cluster configuration itself, which is stored in the
cluster.conf file. Instead, it contains the list of users and clusters and related properties that lu ci
maintains.
1. Execute service luci stop.
2. Execute luci_admin backup [backup_xml_file_path].
Specifying the backup_xml_file_path is optional. If you do not specify a file path, the backup
file will be written to /var/lib/luci/var/luci_backup.xml.
3. Execute service luci start.
Use the following procedure to restore a lu ci database.
1. Execute service luci stop.
2. Execute luci_admin restore -r backup_xml_file_path.
If you do not specify a backup path argument, the command uses
/var/lib/luci/var/luci_backup.xml.
Specifying the -r option indicates that you will replace all configuration with the
configuration specified in the backup file. If you do not specify this option, the default
behavior (which you can also specify with the -u) is to merge any additional configuration
information from the XML backup into the current database.
3. Execute service luci start.
