Backup target access required by NetBackup for OpenStack

The NetBackup for OpenStack solution uses backup target storage to securely place the backup data. NetBackup for OpenStack divides its backup data into two parts:

  1. Metadata

  2. Volume Disk Data

The first type of data is generated by the NetBackup for OpenStack appliance through communicating with the OpenStack Endpoints. All metadata that is stored together with a backup is written by the NetBackup for OpenStack Appliance to the backup target in the JSON format.

The second type of data is generated by the NetBackup for OpenStack nbosdm service running on the compute nodes. The nbosdm service reads the Volume Data from the Cinder or Nova storage and transferring this data as qcow2 image to the backup target. Each Datamover service is hereby responsible for the VMs running on its compute node.

The network requirements are therefore:

  • The NetBackup for OpenStack appliance needs access to the backup target

  • Every compute node needs access to the backup target
