IVssBackupComponents::SetSelectedForRestore method (vsbackup.h)

  • Article

The SetSelectedForRestore method indicates whether the specified selectable component is selected for restoration.

Syntax

HRESULT SetSelectedForRestore(
  [in] VSS_ID             writerId,
  [in] VSS_COMPONENT_TYPE ct,
  [in] LPCWSTR            wszLogicalPath,
  [in] LPCWSTR            wszComponentName,
  [in] bool               bSelectedForRestore
);

Parameters

[in] writerId

Writer identifier.

[in] ct

Type of the component. See VSS_COMPONENT_TYPE for the possible values.

[in] wszLogicalPath

Null-terminated wide character string containing the logical path of the component. For more information, see Logical Pathing of Components.

The value of the string containing the logical path used here should be the same as was used when the component was added.

The logical path can be NULL.

There are no restrictions on the characters that can appear in a non-NULL logical path.

[in] wszComponentName

Null-terminated wide character string containing the name of the component.

The string cannot be NULL and should contain the same component name as was used when the component was added to the backup set using IVssBackupComponents::AddComponent.

[in] bSelectedForRestore

If the value of this parameter is true, the selected component has been selected for restoration. If the value is false, the selected component has not been selected for restoration.

Return value

The following are the valid return codes for this method.

Value Meaning
S_OK
 Successfully indicated that the specified component has been selected to be restored.
E_INVALIDARG
 One of the parameter values is not valid.
E_OUTOFMEMORY
 The caller is out of memory or other system resources.
VSS_E_BAD_STATE
 The backup components object is not initialized, this method has been called during a restore operation, or this method has not been called within the correct sequence.
VSS_E_OBJECT_NOT_FOUND
 The component being selected does not exist in the Backup Components Document, or a live instance of the writer corresponding to that component is not running on the system.
VSS_E_INVALID_XML_DOCUMENT
 The XML document is not valid. Check the event log for details. For more information, see Event and Error Handling Under VSS.
VSS_E_UNEXPECTED
 Unexpected error. The error code is logged in the error log file. For more information, see Event and Error Handling Under VSS.

Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP:  This value is not supported until Windows Server 2008 R2 and Windows 7. E_UNEXPECTED is used instead.

Remarks

SetSelectedForRestore has meaning only for restores taking place in component mode.

SetSelectedForRestore can only be called for components that were explicitly added to the backup document at backup time using IVssBackupComponents::AddComponent. Restoring a component that was implicitly selected for backup as part of a component set must be done by calling SetSelectedForRestore on the closest ancestor component that was added to the document. If only this component's data is to be restored, that should be accomplished through IVssBackupComponents::AddRestoreSubcomponent; this can only be done if the component is selectable for restore (see Working with Selectability and Logical Paths).

This method must be called before IVssBackupComponents::PreRestore.
