Azure Backup Terraform module

Take advantage of fully managed backup of virtual machines and storage accounts in the cloud.

Azure Backup provides independent and isolated backups to guard against unintended destruction of the data on your VMs. Backups are stored in a Recovery Services vault with built-in management of recovery points. Configuration and scaling are simple, backups are optimized, and you can easily restore as needed.

Workflow of this module

Two child modules, storage-backup and vm-backup, are located in the example folder of this module. Therefore, you must execute only storage-backup if you only want to create storage account backups, and you must run the vm-backup module in the example folder if you only want to produce VM backups.

vm-backup module

# Azurerm Provider configuration
provider "azurerm" {
  features {}
}

module "azure-backup" {
	source  = "../../"

	# Name of the azure file sync instance (default "backup")
	name = "backup" 

	create_resource_group = false 

	resource_group_name = "Deepak"

	location = "Central India"

	# (Optional) Prefix to use for all resoruces created (Defaults to resource_group_name)
	resource_prefix = "vm-backup"

	# (Optional) Indicates the name of recovery services vault to be created
	recovery_services_vault_name = "rsv"

    # (Optional) Indicates the sku for the recovery services value to use during creation
	recovery_services_vault_sku = "Standard"

    # (Optional) Indicates which version type to use when creating the backup policy
	backup_policy_type = "V1"

    }
  ]
}

Create resource group

By default, this module will create a resource group and the name of the resource group to be given in an argument resource_group_name. If you want to use an existing resource group, specify the existing resource group name, and set the argument to create_resource_group = false.

If you are using an existing resource group, then this module uses the same resource group location to create all resources in this module.
