Syntax

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

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

Remarks

SPBackupSettings does not override any of its inherited members, and it adds only a single new property: BackupThreads, which specifies the number of threads that the backup operation should use.

Examples

The following example shows how to use the SPBackupSettings class in a backup application. For the full example and a detailed discussion of it, see 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)
