>From the vault pdf, in the section titled:

Determining which duplicate tapes were used, and their host

It says this:

----snip---
Under bpvault, the duplication should normally occur on the
same server that made the original backup, so the host server names should be 
the same for both copies of
the image.

You can confirm this information by using "bpimagelist':

----snip---

In our case, we are doing the entire vault process from our master server. So 
the media host that shows up is the media server that performed the backup for 
the primary copy, but the secondary copy is always the hostname of our master 
server. The problem is that we have media servers that are over a
terabyte in size and if we try to restore with the secondary copy, the master 
server will load the tape and the restore will run over the network rather than 
over our SAN. 

We are going to practice recovering these servers next week but unless we can 
re-assign these images to the proper media servers Netbackup will perform the 
restore over the network rather than using our SAN (we would never finish our 
test in time).

How do we go about re-assigning the images to the media servers that performed 
the backups rather than the media server that performed the copy (our master 
server in this case)?

Thanks in advance,
