Actions
You can start and stop the synchronization with the button in the top right corner. This will enable or disable Backbone from syncing work items and it’s data. You can find more actions 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 work: Import a csv file to pair existing work to be synchronized. This function can only be used when the synchronization is stopped.
Unlink paired work: Remove the connection between work itemsthat are synced together by unlinking paired work.
Download synchronized work: Download all synchronized work items into a JSON file. This can be used for eg. migrate a Backbone synchronization to a new Backbone synchronization.
Take the tour: Shows information about the different tabs and possibilities of the current screen.
Documentation: Open the Backbone documentation (in a new tab)
Create support ZIP: Creates a ZIP file with information about the sync which can be send to the support team
