NetBackup™ Snapshot Manager Install and Upgrade Guide

Last Published: 2023-03-31

Product(s): NetBackup (10.2)

Configuring permissions on Microsoft Azure

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

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

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

    ]
}
}

The following set of permissions are required to use managed identity for discovery, create, delete, database authentication and point in time restore(applicable only for Azure SQL and Managed Instance databases) for supported PaaS databases:

actions": [
															"Microsoft.Authorization/*/read",
															"Microsoft.Subscription/*/read",
															"Microsoft.Resources/*/read",
															"Microsoft.ManagedIdentity/*/read",
															"Microsoft.Sql/*/read",
															"Microsoft.Sql/servers/databases/write",
															"Microsoft.Sql/servers/databases/delete",
															"Microsoft.Sql/managedInstances/databases/write",
															"Microsoft.Sql/managedInstances/databases/delete",
															"Microsoft.DBforMySQL/servers/read",
															"Microsoft.DBforMySQL/servers/databases/read",
															"Microsoft.DBforMySQL/flexibleServers/read",
															"Microsoft.DBforMySQL/flexibleServers/databases/read",
															"Microsoft.DBforMySQL/servers/databases/write",
															"Microsoft.DBforMySQL/flexibleServers/databases/write",
															"Microsoft.DBforMySQL/servers/databases/delete",
															"Microsoft.DBforMySQL/flexibleServers/databases/delete",
															"Microsoft.DBforPostgreSQL/servers/databases/delete",
															"Microsoft.DBforPostgreSQL/flexibleServers/databases/delete",
															"Microsoft.DBforPostgreSQL/servers/databases/write",
															"Microsoft.DBforPostgreSQL/flexibleServers/databases/write",
															"Microsoft.DBforPostgreSQL/servers/read",
															"Microsoft.DBforPostgreSQL/servers/databases/read",
															"Microsoft.DBforPostgreSQL/flexibleServers/read",
															"Microsoft.DBforPostgreSQL/flexibleServers/databases/read"
            ],

If NetBackup Snapshot Manager extension is installed on a managed Kubernetes cluster in Azure, then the following permissions can also be added before configuring the plugin:

"Microsoft.ContainerService/managedClusters/agentPools/read",
"Microsoft.ContainerService/managedClusters/read",
"Microsoft.Compute/virtualMachineScaleSets/write",
"Microsoft.Compute/virtualMachineScaleSets/delete/action"

Additional permissions required by PaaS workloads:

"Microsoft.DBforMySQL/servers/read",
"Microsoft.DBforMySQL/servers/databases/read",
"Microsoft.DBforMySQL/flexibleServers/read",
"Microsoft.DBforMySQL/flexibleServers/databases/read",
"Microsoft.DBforPostgreSQL/servers/read",
"Microsoft.DBforPostgreSQL/servers/databases/read",
"Microsoft.DBforPostgreSQL/flexibleServers/read",
"Microsoft.DBforPostgreSQL/flexibleServers/databases/read",
"Microsoft.Sql/*/write",
"Microsoft.Sql/*/delete"

If you use system managed identity for the PaaS Azure SQL and Managed Instance, apply the same set of permissions/rules to the media server(s) and snapshot manager. If you use user managed identity, attach the same user managed identity to the media server(s) and snapshot manager.

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

For example:

New-AzureRmRoleDefinition -InputFile "C:\CustomRoles\ReaderSupportRole.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/
ReaderSupportRole.json"

Note:

Before creating a role, you must copy the role definition given earlier (text in JSON format) in a .json file and then use that file as the input file. In the sample command displayed earlier, ReaderSupportRole.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 environment.
In NetBackup Snapshot Manager, configure the Azure off-host plug-in with the application's credentials.
