1. The NBU catalog backup will have to go on a tape separate from your data
backups.
1a. If you use the command line to backup the Catalog info, you want to do
the following to ensure you get a clean backup.
/usr/openv/netbackup/bin/admincmd/bprdreq -terminate
bpdbjobs -M $master -report | egrep -i "Active" > /dev/null
NOJOBS=$?
until [ $NOJOBS -ne 0 ]
do
sleep 300
bpdbjobs -report | egrep -i "Active" > /dev/null
NOJOBS=$?
done
tpreq -ev $TAPEID -d $DENSITY -p $POOL -f $MNTFILE
/usr/openv/netbackup/bin/admincmd/bpbackupdb -tpath $MNTFILE \
/usr/openv/var
/usr/openv/netbackup/db
/usr/openv/volmgr/database
/usr/openv/netbackup/bin/initbprd
This terminate bprd so no other jobs will be submitted, then it looks for
any active jobs, if there are we know that the catalog is probably being
updated...so we want to wait for them to finish. when they are done, we do
our bpbackupdb, then restart bprd so backups can run as normal.
2. Yes, I would definitely include the bprecover in your new procedure
3. Setting the Primary copy to the duplicate image is required. The best
way to do this is to keep track of the imageid when you run duplication.
Once you have that information, all you need to do is run either bpimage or
bpduplicate to change the -npc to 2. Primary copy or the original backup
will be copy 1, the duplicate will be copy 2. When you change it with
bpimage or bpduplicate you need to indicate which copy number will be the
new primary, in this case 2.
Does this help?

Ooops I really should have thought of that - thanks. Can I clone the
catalogues onto the same tapes as the normal data?
Should that make the new procedure:
use bprecover to get the catalogues back
restore data to servers
?
I read that in order to restore from a duplicated copy you need to set the
duplicated image to the 'primary copy' in some way - is this the case and
if so how do I do it?

Paul:
Are you not able to recover the NBU catalog?
I'd rather do that than import all those tapes. Importing will take some
time, remember it is a two phase process.
As far as the apps, I'd probably install them versus restoring them,
especially since its NT. Do you have a standard corporate image that you
use for all of your NT servers/clients? Perhaps you could have that on
hand
to expedite your server recovery.
Just some thoughts.

Dear all,
We currently backup our servers using a full dump on weekends, incrementals
during the week. Full dumps are duplicated and sent offsite weekly. I'd
like to do it more frequently but I currently only have two drives, so
cloning during the week is a no-no if I want to be able to do restores!
We have a DR test coming up, during which I will need to restore several of
our servers from the duplicated tapes. I will be provided with a blank
server/LTO drive for NetBackup. Current plan is to do something like this:
Install NetBackup on blank NT Server
Use bpimport to read duplicated tapes into catalogue
Install NT + apps on individual servers
Use NetBackup to restore data
I would be very interested to hear anyone's comments on this. Is it
workable? I have around 400GB to import - how long approximately to create
the catalogue entries? How long to write the actual data back given server
grade kit/NT4/100MB ethernet? Would it be quicker to use NetBackup to
restore the apps as well as the data?
Using NB Datacentre 3.4 on NT4.
Any advice gratefully received!
Cheers,
Paul
