VVR name registration

Inband Control (IBC) messages are used to exchange control information between primary and secondary hosts. A name has to be registered at both the primary and secondary hosts for each replicated volume group before IBC messaging can be used. The VVR snapshot method assumes that the application name is APP_NBU_VVR. To avoid an initial backup failure, you should register that name.

See Testing the replication setup with VVR.

If APP_NBU_VVR is not registered, NetBackup registers the name when the first backup is attempted, but the backup fails. Subsequent backups, however, succeed.
