From dump(8):
Dump honors the user ``nodump'' flag (UF_NODUMP) on regular files and di-
rectories. If a directory is marked ``nodump'', the latter and all files
and directories under it will not be backed up. That is, dump propagates
the ``nodump'' flag on directories.
(Note that the recursive nature of the flag only became available in a
release starting with FreeBSD 4.3).
Restoring a particular directory is quite easy. Interactive mode is my
favourite way of doing that. See restore(8).
