Stop Sync Client Refreshes
You can temporarily stop sync client refreshes, or you can stop refreshes and completely remove all data source information from a sync client.
To close the application and temporarily stop sending data updates to Tableau Online, open the sync client, and on the settings menu in the upper-right, select Exit.
When you exit, the list of data sources and their connection settings remain intact.
To close the application and remove the list of data sources refreshed through the sync client, right-click the sync client icon in the system tray, and select Unlink Sync Client.
Unlinking a sync client also removes all connection information, including stored database credentials.
Exiting or unlinking the sync client does not stop refresh schedules from running on Tableau Online. If you exit the sync client, schedules run, but because there is no connection between your computer and Tableau Online, the published data source is not refreshed.
If a scheduled refresh has occurred while the sync client is closed, you will see an alert on the associated data source the next time you sign in. The next refresh will occur as scheduled, but you can also run it manually when you sign back in.
Remove refresh schedules after you unlink a sync client
If you unlink the sync client, because the schedules for the associated data sources will still run on Tableau Online, you need to remove them manually.
Sign in to Tableau Online, and go to the Data Sources page.
Click the link for the name of the data source you refreshed through the sync client.
On the data source page, select Refresh Schedule,
Select the box next to the schedule you created for the sync client, and then select Actions > Delete.
