Two methods exist to configure an alternate media server in NetBackup.
You must perform one of the following:
Configure the automatic media server failover. This method redirects the restore only if the media server is not available. This method is most useful if the library that contains the media is connected both to the failed media server and the alternate media server. Normally, you configure automatic media server failover before the failure, which results in less time and effort during the restore.
Override the original media server manually. This method forces restores to the alternate server, regardless of the state of the original media server.
All backup and restore requests (not only BMR restores) are directed to the alternate media servers.
