It would have to be a DSU since it is a disk based de-duplication device. Here we use GigE connections to it but Fibre is available (for a price).

Re: [Veritas-bu] how to copy backups from data domain totapew/netbackup 6.5
If you've got a DSU, then I'd suggest starting with bpimmedia, then.
It'll show you what images are on the device.
For example...:
bpimmedia -disk -disk_stu DISK_STU_NAME -d start_date_range -e
end_date_range | awk '$1==IMAGE {print $4}' | tee /tmp/file_of_bpids
This'll give you a list of image id's on the DD storage unit for the
date range specified. bpimmedia has lots of options for selecting
images if you don't want to do it with a simple date range. The awk
on the end just snips out the backup image id.
Put this list of ID's in a file, copy the file to a safe name, too, then
feed the results into bpduplicate with the '-Bidfile' option.
bpduplicate -dstunit TAPE_STU -Bidfile /tmp/file_of_bpids -dp
DSTPOOL -cn 1 -L /tmp/dup.logfile -set_primary 1
Note: bpduplicate expects to duplicate to a tape on that same media
server unless you use the -altreadhost option.
This'll duplicate those disk images to a tape, now you have to go back
and expire the on-disk images or you won't gain your disk space back.
This is why you made a copy of the list of image ID's, the original list
is deleted by bpduplicate (I dunno why - it's always done this, though).
for id in `cat /tmp/file_of_bpids.copy`
do
num_copies=` bpimagelist -backupid $bpid 2/dev/null \
awk 'BEGIN{num=0}{if($1==IMAGE){num=$21}}END{print
num}'`
if [ $num_copies -gt 1 ]
then
echo Expire: $id
bpexpdate -recalculate -backupid $id -d 0 -copy 1 -force
fi
done
So the snipped above reads the backup id's one by one and then checks if
the you've got at least two copies of it. If you do, then it deletes
the first copy.
Note - I'm making an assumption above that you have only one copy of the
data backed up and that one copy is on your disk STU. It's possible
with other arrangements but easier to make this assumption first. It
think it's accurate to what you said earlier.
Hope this helps.

Re: [Veritas-bu] how to copy backups from data domain totapew/netbackup 6.5
One thing you might want to consider for the future..if you have your quarterly
backups in a separate schedule, set up multiple copies of that schedule (in
line tape copy). From that you can write your disk copy and tape copy for your
quarterlies at the same time and set the retention for a longer retention on
the tape copy. This would save you from having to script it if you aren't
great at scripting and don't have vault.

images if you don't want to do it with a simple date range. The awk
on the end just snips out the backup image id.
Put this list of ID's in a file, copy the file to a safe name, too, then
feed the results into bpduplicate with the '-Bidfile' option.
bpduplicate -dstunit TAPE_STU -Bidfile /tmp/file_of_bpids -dp
DSTPOOL -cn 1 -L /tmp/dup.logfile -set_primary 1
Note: bpduplicate expects to duplicate to a tape on that same media
server unless you use the -altreadhost option.
This'll duplicate those disk images to a tape, now you have to go back
and expire the on-disk images or you won't gain your disk space back.
This is why you made a copy of the list of image ID's, the original list
is deleted by bpduplicate (I dunno why - it's always done this, though).
for id in `cat /tmp/file_of_bpids.copy`
do
num_copies=` bpimagelist -backupid $bpid 2/dev/null \
awk 'BEGIN{num=0}{if($1==IMAGE){num=$21}}END{print
num}'`
if [ $num_copies -gt 1 ]
then
echo Expire: $id
bpexpdate -recalculate -backupid $id -d 0 -copy 1 -force
fi
done
So the snipped above reads the backup id's one by one and then checks if
the you've got at least two copies of it. If you do, then it deletes
the first copy.
Note - I'm making an assumption above that you have only one copy of the
data backed up and that one copy is on your disk STU. It's possible
with other arrangements but easier to make this assumption first. It
think it's accurate to what you said earlier.
Hope this helps.

Subject: RE: [Veritas-bu] how to copy backups from data domain
totapew/netbackup 6.5
Thanks for the many replies, and my apologies for taking awhile to
respond. I just got off of a very long support call with Data Domain
and I mentioned the tape backups to the tech I was working with. The
Data Domain device is setup as a disk storage unit. It has VTL
capabilities but the VTL has not been setup yet. The tech recommended
that we setup VTL but wanted me to check with our assigned systems
engineer before proceeding. We have one Win 2003 server as our master
server, and we have a Quantum Scalar i500 that holds our tapes. Before
the Data Domain everything was going to tape. I am not certain just yet
if the VTL setup is required to copy to the tapes or not, or if I can
just script something out and go?
It is becoming increasingly critical for me to find a way to get the
backups off of the Data Domain and get them to tape. Currently our
retention periods are set at 3 months for all backups. Our corporate
policy states we must take the quarterly fulls to tape and archive them
offsite. The problem is that we have yet to grab our 4th quarter tape
backups for 2008 and we are getting closer to running out of time. Also
the Data Domain is nearing it's maximum capacity. So the plan is to get
the 08 4th quarter fulls off to tape and then drop our retention periods
down to 1 month from 3 month to help free up space.
I will do some research here shortly about the bpduplicate command and
see what I can come up with. I'm not that great at scripting but I can
normally find my way around. I hope the extra information helps. If
anyone else has more advise please chime in. I appreciate all the quick
responses.
Thanks,
Tony H.
