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.

Beispiele

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Reference the AdventureWorks2012 database.
Dim db As Database
db = srv.Databases("AdventureWorks2012")
'Store the current recovery model in a variable.
Dim recoverymod As Integer
recoverymod = db.DatabaseOptions.RecoveryModel
'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.Action = BackupActionType.Database
bk.BackupSetDescription = "Full backup of AdventureWorks2012"
bk.BackupSetName = "AdventureWorks2012 Backup"
bk.Database = "AdventureWorks2012"
'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.
bk.Devices.Add(bdi)
'Set the Incremental property to False to specify that this is a full database backup.
bk.Incremental = False
'Set the expiration date.
Dim backupdate As New Date
backupdate = New Date(2006, 10, 5)
bk.ExpirationDate = backupdate
'Specify that the log must be truncated after the backup is complete.
bk.LogTruncation = BackupTruncateLogType.Truncate
'Run SqlBackup to perform the full database backup on the instance of SQL Server.
bk.SqlBackup(srv)
