Just giving us Job Details does not help. 

How is the Policy configured? What is the Transport type selected in the policy?

Please go through these TNs for best practice and troubleshooting of various trasport types:

https://www.veritas.com/support/en_US/article.100039120

https://www.veritas.com/support/en_US/article.100030882

You need vxms log on the host configured as backup host.
