When restoring a file system that contains a volume mount point, only the mount point (directory) is restored. The data on the volume mounted on that directory is not restored.
dsmc restore {\\storman\c$}\mount
The braces ({ and }) are required if you also backed up the data on
the mounted volume from the mount point. Without the braces, Tivoli® Storage Manager restores
data from the file space with the longest name that matches the file
specification. If you backed up the data through the mount point,
the backups are stored in a file space named \\storman\c$\mount.
The braces are used to specify that the data be restored from the \\storman\c$ file
space.
