取得或設定要用於備份作業的執行緒數目。

Namespace:  Microsoft.SharePoint.Administration.Backup
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

Syntax

'宣告
Public Property BackupThreads As Integer
    Get
    Set
'用途
Dim instance As SPBackupSettings
Dim value As Integer

value = instance.BackupThreads

instance.BackupThreads = value

public int BackupThreads { get; set; }

Property value

Type: System.Int32
Int32 代表要使用的執行緒數目。預設值為 1。

備註

BackupThreads必須設為值，從 1 到 6。

將BackupThreads設定為 1 以上的值可能會使spbackup.log檔案位於Location，讀取更困難。

下列範例會示範如何在備份的應用程式中使用BackupThreads屬性。完整範例和它的詳細的資訊，請參閱 ＜ How to: Programmatically Back Up Content。
