About restoring NetBackup media servers
You can restore NetBackup media servers if they are protected as BMR clients (exception: you cannot restore a media server that is co-located with a NetBackup master server).
The following options exist for restoring NetBackup media servers:
If you back up a media server to a different media server, restore the protected media server as you restore any protected client.
A media server can back up its own data using SCSI-attached storage devices or SAN-attached storage devices. If this is true for you, use BMR to restore the media server by first configuring NetBackup to use an alternate media server.
