 * This extension consists of a coordinator and a SQL plugin. While the coordinator is responsible for triggering workflows for various operations like configure backup, backup and restore, the plugin is responsible for actual data flow.
 * To be able to discover databases on this VM, Azure Backup creates the account `NT SERVICE\AzureWLBackupPluginSvc`. This account is used for backup and restore and requires SQL sysadmin permissions. The `NT SERVICE\AzureWLBackupPluginSvc` account is a [Virtual Service Account](/windows/security/identity-protection/access-control/service-accounts#virtual-accounts), and so doesn't require any password management. Azure Backup uses the `NT AUTHORITY\SYSTEM` account for database discovery/inquiry, so this account needs to be a public login on SQL. If you didn't create the SQL Server VM from Azure Marketplace, you might receive an error **UserErrorSQLNoSysadminMembership**. If this occurs [follow these instructions](#set-vm-permissions).
 * Once you trigger configure protection on the selected databases, the backup service sets up the coordinator with the backup schedules and other policy details, which the extension caches locally on the VM.
-* At the scheduled time, the coordinator communicates with the plugin and it starts streaming the backup data from the SQL server using VDI.

 * The plugin sends the data directly to the Recovery Services vault, thus eliminating the need for a staging location. The data is encrypted and stored by the Azure Backup service in storage accounts.
 * When the data transfer is complete, coordinator confirms the commit with the backup service.
