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.

copy backups from data domain totapew/netbackup 6.5
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.
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!
