Planning your SQL Server deployment

Deployment overview

Microsoft supports the deployment of SQL Server on a single server or in a high-availability environment. With high-availability environments, Microsoft supports Failover Clustering in an Active/Passive configuration (SQL Server 2014 and earlier), which is based on the Microsoft Cluster Service (MSCS). Microsoft also supports Failover Clustering in an Active/Active configuration with AlwaysOn Availability Groups (SQL Server 2012 and later), which is based on Windows Server Failover Clusters (WSFC).

If you are using SQL Server 2017 or later, you can use SQL Server on Linux to generate VDI backups. For more information on SQL Server for Linux, see

Deploying the plug-in in these environments is almost identical because the Plug‑in for SQL Server is installed on the server that hosts the SQL Server database. The following topics describe how the Plug‑in for SQL Server is deployed in each type of SQL Server deployment.
