4.6. Backing Up and Rest oring t he luci Configurat ion
As of the Red Hat Enterprise Linux 6.2 release, you can use the following procedure to make a
backup of the lu ci database, which is stored in the /var/li b/l uci /d ata/luci . d b file. This is
not the cluster configuration itself, which is stored in the cl uster.co nf file. Instead, it contains the
list of users and clusters and related properties that lu ci maintains. By default, the backup this
procedure creates will be written to the same directory as the l uci . d b file.
1. Execute service l uci sto p.
2. Execute service l uci backup-d b.
Optionally, you can specify a file name as a parameter for the backup-d b command, which
will write the lu ci database to that file. For example, to write the lu ci database to the file
/ro o t/l uci . d b. backup, you can execute the command servi ce luci backup-d b
/ro o t/l uci . d b. backup. Note, however, that backup files that are written to places other
than /var/li b/l uci /d ata/ (for backups whose filenames you specify when using
service l uci backup-d b) will not show up in the output of the l i st-backups
command.
3. Execute service l uci start.
Use the following procedure to restore a lu ci database.
1. Execute service l uci sto p.
2. Execute service l uci l i st-backups and note the file name to restore.
