I didn't find a tremendous amount of documentation on HAL. One of
the best I did find is at this URL:
http://people.redhat.com/davidz/hal/0.4/hal-spec.html
Particularly note the 'hal-device-manager' -- something you can run.
It's mentioned on page 8 of the above specification.
Here is the first thing I absolutely had to do to set up what I have
successfully set up: identify exactly a couple of strings (I chose the
vendor and model) which are reported by my USB hard drives, when they are
powered on.
I had been using 'lsusb -v' and this did NOT give me the strings in
the exact way they were reported. But 'hal-device-manager' does.
If you do want to set this up, one of the things you have to do is see
exactly what your USB disk(s) is/are reporting.
We can help you know what to do next, but you'll have to see exactly
what your device reports.
I then created a directory (/etc/hal/fdi/95userpolicy) and created
two XML files (ending with .fdi) in that directory, which provided the hal
daemon with what it needed to identify the drive, and the name of the
directory to create in /media.

The way I do it is simple to use. I power on either my SimpleTech
USB hard drive (for Saturday morning) or my Western Digital USB hard
drive (for Tuesday morning). The hald identifies the disk, creates the
directory /media/simpletech (for the SimpleTech drive) or /media/wd (for
the Western Digital drive), and things are ready.
There is absolutely nothing I need to do besides assure the USB drive
is powered on before they're needed.
Now, I do typically unmount the drive, by right-clicking the icon
which appears on my GNOME desktop, and choosing "Unmount Volume". This
unmounts the drive; it no longer appears in "mount" output. The directory
is still there. (If I do an ls of /media/simpletech or /media/wd, no
files show up; just as any other directory that are used to mount other
devices/locations on if they are not mounted.) When I power off the
drive, the directory (/media/simpletech or /media/wd) then gets deleted by
the hal daemon.
It may be possible, in your situation, for someone else to unmount
the drive. You may want a little additional research to assure that no
one else can. (Can you assure that only you use root, or only people you
could trust not to unmount the drive if it shouldn't be unmounted use
root? We can discuss your situation.)

This ought to be okay.

Agreed. (It took me longer to figure out the HAL stuff than to get
them working as I wanted with bacula afterward!) :-)

These are likely possible. Other people may wind up helping you more
on bacula-specific configuration. I really have only configured one, my
current backup, configuration. I am actually quite ignorant on bacula
configuration.
(I worked out my own, with much trial and error!) :-)

I believe bacula could/should work with you. It's that much better
if you have time to research your specific points/needs. (I really don't,
right now.)
Let me know, as you look into the HAL specification URL I provided,
what your problems are. I will gladly offer as much help as I can! I
have often enough come to this list hoping someone else with more
experience than I in something could help me! :-)
