Managing backup hosts
A backup host acts as a proxy client which hosts all the backup and restore operations for Microsoft Azure Stack. In case of Microsoft Azure Stack plug-in for NetBackup, backup host performs all the backup and restore operations without any separate agent installed on the Microsoft Azure Stack.
The backup host must be a RHEL 7.4 or later computer. NetBackup supports only the RHEL platform for a backup host.
Consider the following before adding a backup host:
For backup operations, you can add one or more backup hosts.
For restore operations, you can use only one backup host.
A master, media, or client can perform the role of a backup host.
Note:
It is recommended that you use a NetBackup media server or a client as a backup host.
Microsoft Azure Stack plug-in for NetBackup is installed on all the backup hosts.
When using multiple backup host, make sure that all backup hosts are communicating with the media server.
Azure Stack identity providers
For the Azure Active Directory (AAD) identity provider, all backup hosts require connectivity to https://login.microsoftonline.com, Azure Resource Manager endpoints, or Azure blob storage endpoints, which require ports 80 and 443 for communication.
For the Active Directory Federation Services (ADFS) identity provider, all backup hosts require connectivity to Azure Resource Manager endpoints, Azure blob storage endpoints, or ADFS endpoints, which require ports 80 and 443 for communication.
You can add a backup host while configuring BigData policy using the NetBackup Administration Console.
