Backups can be taken and restored as usual in the System Configuration > System Administration > Backup/Restore section of the LoadMaster WUI. Backups and restores should only be performed on the shared IP address because the changes made there are propagated to the other nodes. When restoring, the individual LoadMasters are rebooted, one at a time.

There are certain settings that need to be set in the Virtual Services for them to work with clustering:

  • Transparency must be disabled

  • Subnet Originating Requests must be enabled

  • All Virtual Services must operate at Layer 7.

  • High Availability (HA) mode cannot be used

As a result of these restrictions, there may be issues with restoring a backup taken from a non-cluster LoadMaster on to a cluster LoadMaster and vice versa, because the settings may be incompatible.

When restoring a configuration, you specify what parts of the configuration should be restored:

  • The LoadMaster base configuration only

  • The Virtual Service configuration only

  • The GEO configuration only

  • The ESP SSO configuration only

  • A combination of the Virtual Service, GEO, ESP, and/or LoadMaster base configuration

The base configuration contains the information about the basic configuration of the LoadMaster, that is, the IP addresses of the various interfaces and the keyboard and time zone settings.

The Virtual Service configuration contains only the settings relating to the Virtual Services and the Real Servers.

The GEO configuration contains only the settings relating to the GEO configuration.

Note: GEO does not currently work properly when configured on a LoadMaster in clustering mode (as opposed to High Availability (HA) mode). If you want to use GEO with LoadMasters configured into clustering mode, GEO must be running as a standalone GEO Virtual Machine or configured on a LoadMaster that is not in clustering mode.

The ESP SSO configuration stores the SSO domains, LDAP endpoints and SSO custom image sets. This does not restore the Virtual Service settings - use the VS Configuration option to restore those.
