Restore Failover Properties

The Restore Failover properties apply to selected master servers.

The Restore Failover properties control how NetBackup performs automatic failover to another NetBackup media server in a master and media server cluster, if the regular media server is temporarily inaccessible for a restore.

The automatic failover does not require administrator intervention. By default, NetBackup does not perform automatic failover.

Examples of when to use the restore failover capability:

• Two or more media servers are sharing a robot and each has connected drives. When a restore is requested, one of the servers is temporarily inaccessible.
• Two or more media servers have standalone drives of the same type. When a restore is requested, one of the servers is temporarily inaccessible.

In these instances, inaccessible means that the connection between bprd on the master server and bptm on the media server (through bpcd) fails. Possible reasons for the failure are:

• The media server is down.
• The media server is up but bpcd is not responding (for example, if the connection is refused or access is denied).
• The media server is up and bpcd is all right but bptm is having problems (for example, if vmd is down or bptm cannot find the required tape).
