I don't know the exact answers, but normally, the mount point itself 
is backed up, but Bacula does not descend into it (that is, with "One 
FS = Yes").

"Remembering" the bind mount is not done by Bacula, just as normal 
"mounts" are not remembered by Bacula - if you need those, you pot 
them in /etc/fstab :-)

What happens on Windows is all a big miracle to me, so I can't tell 
you much regarding that.

Cheers,

Arno
