Remarks

The SPBackupRestoreConsole class is also designed to provide a basis on which you can easily build a UI for backup and restore management.

An SPBackupRestoreConsole object loads the first time any of its members is referenced and it remains loaded until the next reset of Internet Information Server (ISS). It uses very little memory, however.

There is never more than one SPBackupRestoreConsole object.

The methods of this class work primarily with objects of the lightweight type SPBackupRestoreConsoleObject. Each object of the latter class represents a particular backup or restore operation.

Examples

The following example shows the many ways in which an SPBackupRestoreConsole object is used 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 = 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)
            {
                // 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
