So it looks like the final word on this is that it is OK to add new
directories to a fileset (or, a more common example in my case, new
filesystems) provided that they are really NEW directories. If I mkfs a
filesystem and add it to my backup, ignore fileset changes ought to be
OK. I suppose a fix could be that if you are newly adding a directory to
a backup and do not wish to do a full backup, you should touch all of
the files in that directory. The question is, what is the lightest touch
one can do that will cause these files to be added.
I would love to hear an explanation about this problem, really... I know
that that is the way it is and that it might be a lot of work to change
it, but it seems to the casual observer that if a directory is currently
in the fileset (even if it was just added), and that directory contains
files, and Bacula does NOT contain any version of them in the catalog,
they should get backed up. Reliance upon filesystem timestamps is
probably not a great idea because timestamps can be played with. Are
they really necessary in a system that uses a catalog?
