• Troubleshooting - Find, analyze, and fix errors affecting this synchronization.

Actions

You can start and stop the synchronization with the button in the top right corner. This will enable or disable Backbone from syncing issues and issue data. You can find more action to perform for your synchronization in the menu (•••) next to it:

• Clear Backbone cache: Clear cached data by Backbone. Backbone caches data from Jira, such as a list of available fields. If a new field is added to Jira and it doesn't show in Backbone, you need to clear the cache so Backbone will load it. 
• Resync: Enables you to trigger a resync.
• Pair Existing issues: Import a csv file to pair existing issues. This function can only be used when the synchronization is stopped. 
• Unlink paired issues: Remove the connection between issues that are synced together by unlinking these issues.

• Download synchronized issues: Download all synchronized issues into a JSON file. This can be used for eg. Migrating a Backbone synchronization to a new Jira instance.

• Take the tour: Shows some hints about the different tabs and possibilities of the current screen.
• Documentation: Open the Backbone documentation (in a new tab)
