Delete a Sync Group

Updated: May 27, 2015


SQL Azure Data Sync Icon

If you need to make changes to a SQL Data Sync (Preview) synchronization that cannot be made to an existing sync group, you must delete then recreate the sync group incorporating the changes in the new sync group. This topic walks you through deleting an existing sync group.

The Microsoft Azure SQL Data Sync plug-in on the Microsoft Azure Silverlight portal has been decommissioned. Going forward, use the Microsoft Azure Management portal, for Azure SQL Data Sync.

You access SQL Data Sync (Preview) via the SYNC tab under SQL Database at the Microsoft Azure Management portal. The SYNC tab is only available when you have one or more sync groups. See the topic How To: Create a Sync Group (SDS) for guidance on creating and modifying a sync group from this portal.

See the Navigation section below for links to topics you should read before you start and guidance on creating and modifying sync groups.

Modifications you can make to a sync group include:

Do not delete any database in the Sync Group before you remove the Sync Group. If a database in the Sync Group does not exist when you attempt to remove the Sync Group you must recreate the database then synchronize it before you remove the Sync Group.

  1. Navigate your browser to the Azure Management Portal.

  2. Click SQL Databases.

  3. Click Sync (Preview).

  4. From the list of sync groups and client agents, select the sync group you want to remove.

  5. Click the Delete button at the bottom of the page.

  6. Confirm that the database was successfully removed and deprovisioned.

Confirm that each database was properly removed and deprovisioned.

  1. Launch SQL Server Management Studio.

  2. For each database that was in the sync group:

    1. Connect to the server that hosts the database you deprovisioned.

    2. Find the database you deprovisioned.

    3. If the database belonged only to this sync group, ensure that there are no tables with “_dss” in the name.
      If there are any tables with “_dss” in the name use the deprovisioning utility, DeprovisioningUtil.exe, to manually deprovision the database.


Deprovisioningutil.exe <connection_string> [/f]
<connection_string> - Specifies the connection string of the SQL Server database or SQL Database instance to be deprovisioned.
[/f] - Deprovision without warning.

SQL Server
deprovisioningutil "Server=(local);Database=NorthWind;Trusted_Connection=True

SQL Database
deprovisioningutil "; Database=NorthwindAzure; User ID=<yourID>; Password=<yourPassword>; Trusted_Connection=False;" /f

SQL Data Sync (Preview) is a feature of SQL Database. From the Azure Management portal you can perform all tasks necessary to create, deploy, and modify a sync group.


Before you start

Before you begin to design and implement your synchronizations, you should be familiar with these topics.
