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.

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.
