This section enables users to manage backup configurations of the load balancer for quick disaster recovery and to clone or migrate configurations from one node to another.

Backup File Contents and Customization #

By default, RELIANOID backup files store the complete system configuration required for disaster recovery, configuration cloning, or node migration. The backup includes configuration files, certificates, and system settings necessary to restore the load balancer to a functional state.

The information stored in a backup file is defined by the backupfor variable located in the global configuration file:

/usr/local/relianoid/config/global.conf

Example of the default configuration:

$backupfor="$configdir $basedir/*.pem $confhttp $rttables $sshConf $snmpdconfig_file $keepalived_conf $conntrackd_conf /etc/hostname $filedns /etc/cron.d/ /etc/ssl/openssl.cnf $confrsyslog";

By default, this configuration includes:

• Load balancer configuration directory
• SSL certificates and private keys (.pem)
• HTTP and farm configuration files
• Routing tables
• SSH, SNMP, Keepalived, and Conntrackd configuration
• System hostname and DNS configuration
• Scheduled tasks
• OpenSSL configuration
• Rsyslog configuration

Administrators may customize the backup content by editing the backupfor variable to include or exclude specific files or directories according to security, compliance, or disaster recovery requirements.
Any change to this variable will affect all future backups generated by the system.

Important !
After modifying global.conf, ensure the changes are validated and documented, as excluding critical files may result in incomplete backups.

Configuration Backups List #

The table below lists all the backups generated and stored in the load balancer.

Name. A descriptive name for the backup file.
Date. The date the backup was created.
Version. The version of the load balancer at the time of the backup.

Backup Actions #

Available actions for backup files include:

• Create Backup. Generate a new configuration backup file.
• Download. Download the backup as a tarball file.
• Restore. Restore previous configurations from the backup storage.
• Delete. Remove the backup from the load balancer.
• Upload backup. Upload and store a backup previously created on the load balancer. This can be useful for cloning configurations from another load balancer.
