Actually, TOP said he had backed up to an
EDL/3DL (EMC Quantum box).
Jeff (Kaplan),
Is it possible to use tape shadowing on
the replicated system, so that the backup to one virtual tape, replicate to
another virtual tape, then eject that virtual tape to create a physical
tape?

dedup/replication
Of course. Deduplicated information
is only that information that is not already duplicated somewhere else on the
storage device. Once you copy the image using bpduplicate to a tape
there is no other copy of the information (so far as the tape is concerned) so
obviously it would create a whole backup using duplicated and non-duplicated
information from the Data Domain to create it.
However, I didn’t see anything by OP
that suggested he was looking to save deduped information to a tape. I
read his post as meaning:
“There is a backup that went to Data
Domain – we would now like to have a tape copy of the
backup.”
The only real trick in what he wrote is
how to get the information from the remote Data Domain to the local
one. Since we don’t do the remote setup here (we use vaulting
to duplicate the local one to tape) I don’t know exactly how that
mechanism works. It may be automatic simply by requesting a
bpduplicate of the image or it may require some step on the Data Domain itself.
I feel confident however that there is a way to get the data from remote to
onsite. Otherwise having a remote unit would be worse than useless.

It is my understanding that Data Domain
deduplicated images get blown back up before going to tape, thereby losing the
deduplication.

If NBU can see it then you can use the
bpduplicate command to copy the image from Data Domain to tape.

dedup/replication
Hello-
Without using OST, is there a way to get a physical tape copy from a
deduped/replicated image?
We have a local EDL/3DL replicating (de-duped data) to a remote EDL/3DL. We
need to get a physical tape from the remote copy, but it has to NBU-aware.
Thanks in advance!
