SPBackupSettings 类

表示配置设置的备份操作，包括要使用的线程数。

继承层次结构

System.Object
  Microsoft.SharePoint.Administration.SPAutoSerializingObject
    Microsoft.SharePoint.Administration.Backup.SPBackupRestoreSettings
      Microsoft.SharePoint.Administration.Backup.SPBackupSettings

命名空间：  Microsoft.SharePoint.Administration.Backup
程序集：  Microsoft.SharePoint（位于 Microsoft.SharePoint.dll 中）

语法

声明
<SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel := True)> _
Public NotInheritable Class SPBackupSettings _
    Inherits SPBackupRestoreSettings
用法
Dim instance As SPBackupSettings

[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel = true)]
public sealed class SPBackupSettings : SPBackupRestoreSettings

备注

SPBackupSettings不会覆盖继承的成员，并添加一个新属性： BackupThreads，用于指定在备份操作应使用的线程数。

示例

下面的示例演示如何在备份应用程序中使用SPBackupSettings类。有关完整的示例和详细的讨论，请参阅How to: Programmatically Back Up Content。

static void Main(string[] args)
{
    // Identify the location for the backup storage.
    Console.Write("Enter full UNC path to the directory where the backup will be stored:");
    String backupLocation = Console.ReadLine();
    
    // Create the backup settings.
    SPBackupSettings settings = SPBackupRestoreSettings.GetBackupSettings(backupLocation, "Full");

    // Identify the content component to backup.
    Console.Write("Enter name of component to backup (default is whole farm):");
    settings.IndividualItem = Console.ReadLine();
    
    // Set optional operation parameters.
    settings.IsVerbose = true;
    settings.UpdateProgress = 10;
    settings.BackupThreads = 2;

    // Create the backup operation and return its ID.
    Guid backup = SPBackupRestoreConsole.CreateBackupRestore(settings);

    // Ensure that user has identified a valid and unique component.
    SPBackupRestoreObject node = EnsureUniqueValidComponentName(settings, ref backup);

    // Ensure that there is enough space.
    Boolean targetHasEnoughSpace = false;
    if (node != null)
    {
        targetHasEnoughSpace = EnsureEnoughDiskSpace(backupLocation, backup, node);
    }

    // If there is enough space, attempt to run the backup.
    if (targetHasEnoughSpace)
    {
        // Set the backup as the active job and run it.
        if (SPBackupRestoreConsole.SetActive(backup) == true)
        {
            if (SPBackupRestoreConsole.Run(backup, node) == false)
            {
                // Report "error" through your UI.
                String error = SPBackupRestoreConsole.Get(backup).FailureMessage;
                Console.WriteLine(error);
            }
        }
        else
        {
            // Report through your UI that another backup
            // or restore operation is underway. 
            Console.WriteLine("Another backup or restore operation is already underway. Try again when it ends.");
        }

        // Clean up the operation.
        SPBackupRestoreConsole.Remove(backup);

        Console.WriteLine("Backup attempt complete. Press Enter to continue.");
        Console.ReadLine();
    }
}// end Main

Shared Sub Main(ByVal args() As String)
    ' Identify the location for the backup storage.
    Console.Write("Enter full UNC path to the directory where the backup will be stored:")

                Console.WriteLine([error])
            End If
        Else
            ' Report through your UI that another backup
            ' or restore operation is underway.

线程安全性

该类型的任何公共 静态 (已共享 在 Visual Basic 中) 成员都是线程安全的。不保证任何实例成员都是线程安全的。
