Configuring permissions on Microsoft Azure Stack Hub

Before NetBackup Snapshot Manager can protect your Microsoft Azure Stack assets, it must have access to them. You must associate a custom role that NetBackup Snapshot Manager users can use to work with Azure Stack assets.

The following is a custom role definition (in JSON format) that gives NetBackup Snapshot Manager the ability to:

Configure Azure Stack Hub plug-in and discover assets.
Create host and disk snapshots.
Restore snapshots to the original location or to a new location.
Delete snapshots.

High availability	(Scale-in) To maintain the state of the VM scale set.	Microsoft.Compute/virtualMachineScaleSets/delete/action

To create a custom role using Powershell, follow the steps mentioned in the Azure Stack documentation.

For example:

New-AzRoleDefinition -InputFile "C:\CustomRoles\registrationrole.json"

To create a custom role using Azure CLI, follow the steps mentioned in the Azure documentation.

For example:

az role definition create --role-definition "~/CustomRoles/
registrationrole.json"

Note:

Before creating a role, you must copy the role definition (text in JSON format) in a .json file and then use that file as the input file. In the sample command displayed earlier, registrationrole.json is used as the input file that contains the role definition text.

To use this role, perform the following:

Assign the role to an application running in the Azure Stack environment.
In NetBackup Snapshot Manager, configure the Azure Stack off-host plug-in with the application's credentials.
