Thanks Mick, but --exclude protects against deletion. My problem was
that I did use
rsync -auHz --delete --exclude=/A/    <SourceDir>/  <DestDir>/
.................................^

because A is a directory on <DestDir>. But it turned out that this
does delete A on <DestDir> since A is a symlink on <SourceDir> and the
include/exclude pattern is applied to the <SourceDir> only.
