In Windows Vista Enterprise, you use the Distributed File System (DFS) together with the Volume Shadow Copy Service (VSS). However, VSS does not show whether the DFS path is the same as the physical path. For example, assume that the DFS path is as follows:

\\myfiles\storage\[alias [file:///\\myfiles\storage\%3calias]]

Assume that the physical path is as follows:

\\severname\FSXX\[alias [file:///\\severname\FSXX\%3calias]]

In this example, VSS does not show whether the alias directory of the DFS path is the same as the alias directory of the physical path.
