Greetings!
I haven't received any replies from my first message, which I sent on
Oct 30, but it was long, and didn't really have a specific question.
(And, I have been overwhelmed with work for most of the time, since, so I
haven't yet done much more on trying to see whether I could run bacula and
mysqld on the Sun. When I try this again [which I hope is within the next
couple weeks or so], I'll come with a specific question, if I have one.)
I do have a specific question now, that relates directly to bacula.
Highlight: is it possible to automount USB drives under a specific
directory, and should I do so, if it is?
A little more background...
My mother just gave me my Christmas present for this year, which is a
Western Digital 320GB external hard drive. (We purchased it at a local
Circuit City last weekend, using a coupon for an extra discount because of
their grand opening.)
I already had a SimpleTech 400GB external hard drive, and I have
bacula backup files on this drive from October 14. So far as I know,
backups to this drive are going very well.
Now, I have formatted the Western Digital hard drive, and the
behavior I see is very similar to the SimpleTech.
In fact, QUITE similar!
Now that they have both been formatted, I can turn either one on, and
within a half minute or so, it gets automounted with the pathlist
"/media/usbdisk". And, the device name is /dev/sdc1 -- again, no matter
which drive gets turned on first. (If I turn the other one on while the
first is still on/connected, it gets automounted to /media/usbdisk1, and
the device name is /dev/sdd1.)
I very much like the idea of having two independent USB drives, so
that if something happens to one, I still have backups on the other.
And, in fact, I have left the schedule for the SimpleTech drive to be
Saturday mornings, for the full/differential backup and catalog.
I am, this next week, planning on doing a full/differential backup to
the other USB device (the Western Digital one), every Tuesday morning.
That way, if something happens to either device, I still have a backup
within the last week, on either one that is still working.
So far as I know (but remember, I'm brand new to bacula), the file
and catalog backups (on the appropriate date) contain everything needed to
access/restore. The MySQL files are on my Linux internal hard disk, but I
don't *think* it knows the pathlist which was used.
The way I am planning it at the moment, I will turn the SimpleTech
drive on before Saturday morning's backup, and the Western Digital one on
before Tuesday morning's backup, and the pathlist will be /media/usbdisk,
no matter which drive is being used. And, the device name will be
/dev/sdc1, no matter which drive.
Therefore, I have not made any changes to the bacula-sd.conf file.
But, it keeps "creeping" into my mind that perhaps it would be good
to have a specific directory pathlist for them both, and when the Western
Digital drive was powered on, it would be mounted to a specific -- and the
same -- pathlist, and the same for the SimpleTech drive, to a different,
but specific and the same, pathlist.
Can I do this? They are both USB devices. Right now, they are both
attached to my system, as it has two USB ports. So, the port number would
be different, not that it matters. (And, it is certainly possible that
they could be interchanged, and the SimpleTech drive could come through
the Western Digital port and vice versa.)
I like it being automounted. I turn them on, the day before the
backup. I turn them off, usually during the day after the backup. I like
them being automounted -- just in the convenience (or is it laziness)
sense of it. :-) But, can they be uniquely identified, and automounted
to a specific directory? (I'm reading auto.master, autofs, automount,
etc., but I haven't finished deciding, yet.)
And, IF I *can* do this, should I?
If anyone who is much more experienced with bacula and/or USB devices
than I am has any suggestions, I would love to hear them! :-) (I also
hadn't even used USB devices until I went to Fedora Core 4 in September,
so I'm also not experienced with them. I googled and figured out how to
format them, and they seem to be working, great! But, I just don't know
about this unusual situation.)
Thank you!
Barry
