Are you using VTL Plus version 1 or 2? As version 2 Release 3 now offers
NDMP 4 which enables NBU to incorporate any physical devices visible to
the VTL into a NBU storage unit.
What this means is that your VTL would become the data mover over FC as
apposed to your current setup where your duplication is happening over
ip by means of a vault server. All copies are now visible to NBU with
this method as apposed to legacy "tape Caching" or "Auto-Archving".
NBU 6.5 is needed, however you can see the benefits, all NBU lifecycle
management would stay the same.

Subject: Re: [Veritas-bu] Vault question
Bill-
By default, NetBackup will read from the media server which originally
did the backup (i.e. "owns" the media). Bpduplicate (which is what Vault
uses to duplicate images) does the same thing, so you would want to
choose the storage unit that belongs to the media server that originally
wrote those images.
If you end up duplicating images in one profile owned by multiple media
servers, you can use the "Advanced Duplication" check-box on the
Duplication tab. Only down side to that is you have to pre-allocate how
many drives on each media server will be "used" for duplication. That
read/write drive selection basically means how many bpduplicate
processes will be started using that media server and storage unit. If
you do not specify the "alternate read host", then, by default,
bpduplicate will mount the original media on the media server that owns
it.
The problem that most folks will get into with this, is that they will
use the basic duplication screen and select a storage unit for the
destination. If they do not filter using the "Choose Backups" tab, then
they could potentially duplicate a bunch of images from one media server
to another, which causes the data stream to go over the network to the
destination media server.

Hi,
Environment
Running NBU 5.1 MP6. Windows master, 1 Windows and 2 Solaris media
servers. Using a Sun VTL+ for primary backup and then vault to physical
tape. I have separate vaults for each media server. I use different
profiles for different retention periods for the physical tape. The VTL
drives are in a separate storage unit from the physical drives.
Question
When I dupe images, does it matter which storage unit I select in the
profile? Should I use the SU that the primary image resides on?
Please let me know if this is not enough info to answer my question.
Thanks,
