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.

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.
-M

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.

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
Hi,
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!
B/R,
Tony H.
