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.
