To perform a database backup operation using SQL Server Management Objects (SMO), the application specifies the operation process by setting Backup object properties, and then it calls the SQLBackup(Server) method.

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Reference the AdventureWorks2008R2 database.
Dim db As Database
db = srv.Databases("AdventureWorks2008R2")
'Store the current recovery model in a variable.

'Define a Backup object variable. 
Dim bk As New Backup
'Specify the type of backup, the description, the name, and the database to be backed up.

bk.BackupSetName = "AdventureWorks2008R2 Backup"
bk.Database = "AdventureWorks2008R2"
'Declare a BackupDeviceItem by supplying the backup device file name in the constructor, and the type of device is a file.
Dim bdi As BackupDeviceItem
bdi = New BackupDeviceItem("Test_Full_Backup1", DeviceType.File)
'Add the device to the Backup object.

'Set the Incremental property to False to specify that this is a full database backup.
