The original poster was referring to backing up softlinks, not using
them as backup devices/locations.
Bacula will back up the link, if I'm not mistaken, but not the data
underneath. This affects me for the following reason: let's say my list
includes /usr/local/bacula. I prefer this because I'm absent-minded and
don't like to change the name. Welp, it will backup /usr/local/bacula
alright, but it will NOT backup /usr/local/bacula-1.38.11, which is what
the link really points to.
I would personally like the option to follow symlinks, though I really
only use them for directories. I could see them being a problem on
systems where /bin is a symlink to /usr/bin, or other strange things
that I've seem on default OS installs lately.
