パラメーター

説明

SQL Server 管理オブジェクト (SMO) を使用してデータベースのバックアップ操作を実行するため、アプリケーションは Backup オブジェクト プロパティを設定することにより操作プロセスを指定し、SQLBackup(Server) メソッドを呼び出します。

使用例

VB

'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.
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 AdventureWorks2008R2"
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.
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)

Powershell

$bk.Action = [Microsoft.SqlServer.Management.Smo.BackupActionType]::Database
$bk.BackupSetDescription = "Full backup of AdventureWorks2008R2"
$bk.BackupSetName = "AdventureWorks2008R2 Backup"
$bk.Database = "AdventureWorks2008R2"
$bdi = new-object Microsoft.SqlServer.Management.Smo.BackupDeviceItem("Test_Full_Backup1", [Microsoft.SqlServer.Management.Smo.DeviceType]::File)
$bk.Devices.Add($bdi)
$bk.Incremental = $FALSE
$backupDate = new-object System.DateTime(2006, 10, 5)
$bk.ExpirationDate = $backupDate
$bk.LogTruncation = [Microsoft.SqlServer.Management.Smo.BackupTruncateLogType]::Truncate
