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.

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.
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).
In our environment we
DO have Vaulting so we regularly vault from the DSU to tape for those items that
require offsite storage.
One alternative to that
(which we don’t use) is to get a second Data Domain and put it at an offsite
location then use Data Domain’s ability to copy images directly to the offsite
unit from the onsite unit.

Is the data domain a
DSU for netbackup?
When you say you're
backing up to it, can you give more details?

You can use the
bpduplicate command to copy one backup image to another. The source
image can be Data Domain and the target can be tape. If you know scripting
it should be fairly easy to create a script that calls this command.
Type “man bpduplicate” for more details on the command. Look at the
storage unit options for setting source and
destination.

Subject: [Veritas-bu] how to copy backups
from data domain to tapew/netbackup
6.5
This is the first time
for me using this mailing list. This list was recommended to me by
someone and here I am.
Here is my current
dilemma:
We went to using a Data Domain
device along with NetBackup 6.5 in late December. We do not have the Vault
add-on for NetBackup. Currently all of our backups are going to the Data
Domain. Our corporate policy requires us to make quarterly full
backups to tape. I am trying to figure out how I
can copy backups off of the Data Domain to a tape library. I was
told that this can be done with the help of some scripts but, I have not been
able to find any information on how to do this or where to even begin though my
research attemps. I am hoping someone on this mailing list has experience
with this process, or is willing to point me in the right direction.
Please reply if you can help and many
thanks!
