SPBackupRestoreConsole.CreateBackupRestore 方法 (SPBackupRestoreSettings)

项目
05/13/2015

创建备份或还原操作，并为其分配一个 id。

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

语法

声明
Public Shared Function CreateBackupRestore ( _
    settings As SPBackupRestoreSettings _
) As Guid
用法
Dim settings As SPBackupRestoreSettings
Dim returnValue As Guid

returnValue = SPBackupRestoreConsole.CreateBackupRestore(settings)

public static Guid CreateBackupRestore(
    SPBackupRestoreSettings settings
)

参数

settings
类型：Microsoft.SharePoint.Administration.Backup.SPBackupRestoreSettings

设置为备份或还原操作的图案。

返回值

类型：System.Guid
Guid 标识新的备份或还原操作。

异常

异常	条件
ArgumentNullException	settings是空引用（无在 Visual Basic 中）。
SPException	该组件已经预定的备份或还原。

备注

在备份或还原操作是一个SPBackupRestoreConsoleObject对象。返回Guid为您的代码可以引用该操作时，它调用SPBackupRestoreConsole的关键成员的主要方式。例如，您使用Guid的SetActive， Run和Remove方法的参数。

如果您想要获取对SPBackupRestoreConsoleObject对象的直接引用，请使用Get。

CreateBackupRestore方法还会创建一个SPBackupRestoreHistoryObject对象，该对象具有相同的SPBackupRestoreConsoleObject对象 ID。

示例

下面的示例演示如何在备份应用程序中使用CreateBackupRestore方法。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 = 10;

    // 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)
