SqlBackup メソッド
使用される Backup オブジェクトのプロパティでの指定どおりに、データベースのバックアップ操作を実行します。
名前空間: Microsoft.SqlServer.Management.Smo
アセンブリ: Microsoft.SqlServer.SmoExtended (Microsoft.SqlServer.SmoExtended.dll)
構文
'宣言
Public Sub SqlBackup ( _
srv As Server _
)
'使用
Dim instance As Backup
Dim srv As Server
instance.SqlBackup(srv)
public void SqlBackup(
Server srv
)
public:
void SqlBackup(
Server^ srv
)
member SqlBackup :
srv:Server -> unit
public function SqlBackup(
srv : Server
)
パラメーター
- srv
型: Microsoft.SqlServer.Management.Smo. . :: . .Server
バックアップ操作のソースである Microsoft SQL Server インスタンスを表す Server オブジェクトです。
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
$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")

$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
