In this video David demonstrates how to configure Azure Data Sync 2.0 to synchronise an Azure SQL database with an "On premises" SQL server.

As the name suggests the Azure Data Sync tool allows you to synchronise data between Azure SQL databases and other databases both on Premises and in the Azure cloud.

If you are looking to manage a 'hybrid' environment where you have data and on premises data then this might be a useful tool for you.
