CVssWriter::GetRestoreType method (vswriter.h)

The GetRestoreType method returns the type of restore a writer is participating in.

GetRestoreType is a protected method implemented by the CVssWriter base class.

Syntax

VSS_RESTORE_TYPE GetRestoreType();

Return value

This method returns the type of restore operation a writer is participating in, in terms of values of the VSS_RESTORE_TYPE enumeration.

If GetRestoreType is called during a backup operation, the return value is undefined.

Remarks

This method should be called only during restore operations.

The default restore type is VSS_RTYPE_UNDEFINED. However, writers should treat this restore type as if it were VSS_RTYPE_BY_COPY.

A requester can set the restore type by calling the IVssBackupComponents::SetRestoreState method.

A requester can call IVssBackupComponents::SetRestoreState anytime prior to its generation of a PreRestore event with the IVssBackupComponents::PreRestore method. Therefore, to obtain the correct restore type, a writer should not call GetRestoreType prior to handling the PreRestore event in CVssWriter::OnPreRestore.
