Disaster recovery

Edit online

Ensure that you regularly back up the components that are specific to your deployment type, so that you can perform disaster recovery when needed.

Important: Backups of the database are crucial for performing disaster recovery. They should be scheduled to run regularly and before every upgrade of License Metric Tool. Backups of the License Metric Tool server are of less importance. However, they make restoring the environment easier.

Component Comment
License Metric Tool database
The License Metric Tool data is stored in the database. For more information, see the following links:
License Metric Tool server
The following custom settings are saved in the License Metric Tool server:
  • SSO configuration
  • Modifications to truststores and keystores (for example, added trusted certificates)
  • Custom settings on the Advanced Sever Settings panel
  • Log settings
If you do not customize any of these items, you do not need to back up the License Metric Tool server. Otherwise, back up the following directories:
  • Installation registry
    • Linux /var/.com.zerog.registry.xml

      This file is hidden. To view it, run the ls -la command. If you installed the server as a non-root user, the registry is in $HOME/.com.zerog.registry.xml.

    • Windows C:\Program Files\Zero G Registry\.com.zerog.registry.xml

      This file is hidden. To view it, change the Folder Options in Control Panel to display hidden files, or type the complete path in the address bar of any open window.

  • Installation directory
    • Linux /opt/ibm/LMT
    • Windows C:\Program Files\ibm\LMT
