Restore mode is suitable for the case when you want to create a "staging" Jira instance, which is an exact copy of the "production" Jira instance (a.k.a refresh staging from production). Using Configuration Manager to achieve that is much faster than restoring an XML backup of the "production" system to the "staging" system. Sometimes using Configuration Manager is the only possible way to transfer configurations and issues, especially when you're working with large Jira instances, where creating a backup leads to performance degradation of the production system and the backup is so large that you're not able to transfer it and restore it to the "staging" systemdue to its size. Using Configuration Manager will allow you to perform such a "refresh" in just a few minutes compared to hours for really large Jira instances.
