Mark,
Thanks for this information, it is very useful!
>From my experiance with Netbackup, the command line is a quick and easy
method to achieve your desired result but with a cost that it is not
intuative and you have to know the exact command you want in order to
acomplish this.
Ideally I would like a foolproof system which would allow an operator to
come into work on Monday morning and perform all the tasks needed - that is
my next question, what sort of tasks does an operator need to do to ensure
that everything is OK?
I would like, if possible to look at your inject and vaulting scripts. I
would guess not since you have spent alot of time on them ;) - what kind of
things do the scripts do, and how does the vaulting element work?
In regards to cold backup of oracle. How does this extend to other
applications? We use Veritas Cluster here and it would be very easy to
create scripts to stop/start services. Where do I place the scripts for
these?
Regards,
Tim.

Subject: RE: [Veritas-bu] Operator tape removal & backup scripts
Our operators work almost entirely from scripts I've written. The use of
the command-line is not unusual in this office and using the command line
lets me force exactly the operation I want to occur without fear that
they've mis-clicked and forgotten to set some option box or something. By
running my "inject_tapes" script, as opposed to using the media management
gui, my operators use exactly the options, barcode rules, etc. that I want
to happen every time.
My tape rotation script, for vaulting tapes, is triggered as a cron job, it
identifies the tapes to be removed and automatically moves them to the
mailslots. It sends an email with the tapes to be removed & supplies a list
of tapes to be inserted in their stead. It then pages the operator that
there's a rotation task to be performed.
I use a similar strategy with the weekly duplication process.
Cold backups of applications are best handled as you mentioned, with start &
stop scripts as used by Netbackup. This allows you to reschedule your jobs
and the start/stop stuff moves with it. My Oracle environment is very
complex so my start/stop script is probably not applicable to your
environment but it's pretty much a matter of calling the dbshut & dbstart
scripts in your Oracle's $ORAHOME/bin directory to make it happen.
I also backup to disk, although I have a scheduled job that reaps it to tape
to keep from filling up the disk space (duplication of image to tape, then
forced expiration of disk image). The thing to remember with disk is that
it isn't compressed, unless you're using the NB client-side compression (and
that costs big CPU and frankly isn't that good a compression algorithm).
Tape is still usually a cost savings over disk so you'll want to be careful
with that.
You'll use more disk that tape, in my experience, as measured by just
GBytes.
HTH - Mark

Subject: [Veritas-bu] Operator tape removal & backup scripts
Hiya,
I have a couple of questions regarding NetBackup 3.4 (running on Solaris).
OK, the first is - what should your operator do when removing tapes from
netbackup and putting in the safe? Do people duplicate tapes, move them into
volume groups for particular days? - do operators generally use the GUI
interface rather than the command line?
The other question is how do I perform cold backups of applications? As I
understand it I can use backup start & stop scripts which will force the
application to shutdown prior to backup and then resume after? Does anyone
have any examples for Inktomi or Oracle?
I am also looking for alternatives for tape backup. At the moment we perform
full backup's everynight. We use a lot of tapes per week and I am curious to
see if anyone has implemented backups to disk etc?
Thanks,
Tim.
