I have a single netbackup domain backing up to an hp storeonce OST compatible disk device.The storeonce does not have path to tape capability.
there is a secondary OST device at a remote site but in same netbackup domain as AIR not currently supported.
backups will be performed at both sites and cross replicated via OST optimised duplication. Tape copies are also required and the tape library is located at the primary site.
I have setup an SLP which performs a backup to the primary OST device then performs 2 duplications one to a secondary OST device via optimised duplication and one to a tape library at the primrary site.
In order to allow all media servers to have access to both OST devices it is necessary to add the all of the media servers under credentials for the storage servers.
The OST optimised duplication is working fine as is the tape copy however randomly the media server selected to perform the read from the OST storage at the primary site to send to tape is one from the remote site. This means that data is being read across the WAN to rehydrate and then sent back across the WAN again to the media servers with access to the tape library.
Not having the remote media server ticked in the OST source storage unit definition makes no difference as for duplications from OST devices the allowed read media servers are taken from the credentials of the storage server.
Is it possible to prevent the remote media server from being used during the duplication to tape process.
