Table: NetBackup terminologies
A backup job for OpenStack data is a compound job.
When a backup job is executed, first a discovery job is created. The discovery job communicates with the controller node and gathers information of the instances and associated volumes (cinder) that needs to be backed.. At the end of the discovery, the job populates a workload discovery file that NetBackup then uses to distribute the workload amongst the backup hosts.
For backup, a separate child job is created for each backup host to transfer data to the storage media. A child job can transfer data blocks from multiple Region servers.
The NetBackup parallel streaming framework allows the instances and associated volumes (cinder) backed up using multiple backup hosts sequentially.
The backup host acts as a proxy client. All the backup and restore operations are executed through the backup host.
You can configure media servers, clients, or a master server as a backup host.
The backup host is also used as destination client during restores.
The BigData policy is introduced to:
Controller node is referred to as a application server in NetBackup.
