nbosdmapi
The nbosdmapi service is the connector between the NetBackup for OpenStack cluster and the data mover running on the compute nodes.
The purpose of the nbosdmapi service is to identify which compute node is responsible for the current backup or restore task. To do so, the nbosdmapi service connects to the nova API database requesting the compute host of a provided virtual machine.
Once the compute host has been identified the nbosdmapi forwards the command from the NetBackup for OpenStack Cluster to the data mover running on the identified compute host.
