You will find the page Backup & restore (previously “Snapshots of Config”) under the Common tab in Kantega SSO Enterprise.
You then click “create snapshot”
Your snapshot will then show in the list:
These snapshots can be found as .zip files in the home folder of your Atlassian server, under kerberos_snapshots
You can for example move this .zip to a new cluster, and add it under a home directory with the exact name kerberos_snapshots, and a config from the production environment can be mirrored in a staging environment.
