There has been a bunch of discussion, and some bugs, about bacula's
handling of MS Windows junction points.  I can't tell what the current
status is.  Does anybody know?

3 possibilities that occur to me are
1. bacula descends into mount points.  In the case of Vista, this seems
likely to create an infinite loop.
2. bacula skips mount points completely, not even recording anything for
them.
3. bacula records mount points as mount points, restores them properly,
and does not descend into them.

3 seems like the best behavior.  1 and 2 have both been reported(!).
Kern's response to http://bugs.bacula.org/view.php?id=1267 seems to
indicate he think it works, i.e. something like 3.

The most topical thing I've found is
http://www.mail-archive.com/bacula-devel AT lists.sourceforge DOT 
net/msg00056.html
which provides a list of stanard junction points to exclude for Vista.

Junction points have been a feature of Windows for quite awhile, but
Vista seems to be new in making extensive use of them.

Thanks.

P.S. Windows now has at least 3 different link-like technologies: link
files aka Windows shell shortcuts or .lnk files, junction points, and
DFS mounts.  http://en.wikipedia.org/wiki/NTFS_reparse_point indicates a
blizzard of link or mount-like windows technologies.  Helpfully, the
terminology keeps changing.
http://msdn.microsoft.com/en-us/library/bb524801(VS.85).aspx says "In
earlier documentation, DFS links were called junction points."  Since
DFS links can span physical file systems while junction points (in
Vista) can not, these are definitely 2 different tools.
