Here is a summary of the pros and cons of using a hosted service versus a client side tool.
- You do not need to install components locally and your machine is does not need to be connected to Windows Azure during import/export operations.
- To import, you have to put your bacpac in an Azure Blobstore separately (the tool does not do it for you). Additionally, the Windows Azure SQL Database Import/Export unsurprisingly only works with Azure. If you need to import or export to an on premise
database you must use the client side tools.
Client Side Tools
- Works against on-premise SQL Servers as well as Azure. Additionally, also supports the file formats generated by the Import/Export Service so you can pass BACPACs back and forth between the client and the service.
- You need to install several redistributable components on your local machine which will actually do all the work.
