It was great just to finally figure this out! :-O I mean, I did
understand, after I tried it, that bacula could not be expected to deal
with two different disk devices on the same pathlist!
So, it was absolutely mandatory that I get them mounted to different
pathlists. I know I have ridiculously little time (at home) to deal with
this, right now, but in two to three weeks, I sure wasn't successful!
That's one of the reasons I was considering not using bacula right now.
Here was a very important point: I didn't know about the
hal-device-manager! In the Fedora Forum, in doing the equivalent of
"googling" within the forums there, I found an article where the man said
something like I haven't found much documentation on hald. But, he said
one web site was good. I went there. It is good. It is a 48-page
manual, and the information there finally allowed me to make progress!
And, when I ran hal-device-manager, I was able to see *exactly* what
my USB devices were reporting! And, it did not match what I had been
seeing with lsusb -v! (But, lsusb was the *only* command I knew before.)
I had asked Josh, I believe, how could I be certain that what I was seeing
in the lsusb output matched things like
block.storage_device:storage.vendor and
block.storage_device:storage.model? Those exact strings are shown in the
hal-device-manager, when the USB device is turned on! Seeing that, my
placing the appropriate things in the two above fields matched on the
first try, for both disks! :-)
So, I consider this problem now solved. And, in the remaining time I
have to give it, this weekend, I'll make changes to my bacula
configuration files.

Thank you for being the kind of person/programmer who desires
information from people using your software that will allow you to improve
the software and/or documentation! I will!

Well... bacula does okay right now with pathlists that disappear...
<sigh>
Yep! Guess what? Last night, I edited the bacula-sd.conf file and
changed "/media/usbdisk" to "/media/simpletech" -- since the SimpleTech
drive was the one I had turned on to do Saturday morning's backup.
Then, I was so beyond exhausted, I went to bed.
Well... er.... <sigh>... "DUHHH"... I forgot to restart the bacula
daemons! :-( So, guess what I see this morning? YEP! Here's an
example:

Gee! It was trying to use /media/usbdisk. It said no such file or
directory. This is great, in terms of that what I want bacula to do if
the drive isn't online, because I don't want the backup to be on the same
partition as my file system. So, I'm happy enough with bacula here, in
terms of a good reaction to the pathlist not being present.
I just need to remember to restart the daemons! <sigh> :-)
Well, now I'm planning on having the bacula daemons in place by the
beginning of February, and we'll see what my full on Saturday to the
SimpleTech/full on Tuesday to the Western Digital, differential other
Saturdays/Tuesdays does in February.
Thank you again!
Barry
