SQL Azure Data Sync Logo

A synchronization group is two or more databases that are logically grouped together for the purpose of synchronizing specified tables, columns and rows common to each.

The members of your synchronization groups are governed by your business needs and may contain only SQL Azure or a mix of SQL Server and SQL Azure databases. This article walks you through the steps to create a SQL Azure Data Sync synchronization group. The only requirement is that each sync group must have at least two databases, one of which is a SQL Azure database – which serves as the sync group hub.

Name the Sync Group

The first step in the process to create a sync group is to give the sync group a unique and meaningful name. For a sync group that synchronizes all sales data from the regional offices to corporate headquarters you might want to name it SalesReportSG. For details on how to name your sync group see the article SQL Azure Data Sync Name a Sync Group.
