 # Back up Azure Disks using Azure Data Protection via REST API

 ## Prerequisites
 
+Before you back up disks, ensure that you:

 - [Create a Backup vault](backup-azure-dataprotection-use-rest-api-create-update-backup-vault.md)
 
 - [Create a disk backup policy](backup-azure-dataprotection-use-rest-api-create-update-disk-policy.md)
 
 ## Configure backup

+- **Disk to be protected**: Note the ARM ID and the location of the disk to be protected. This will serve as the identifier of the disk.
 
-The disk snapshots are stored in a resource group within your subscription. As a guideline, we recommend creating a dedicated resource group as a snapshot datastore to be used by the Azure Backup service. Having a dedicated resource group allows restricting access permissions on the resource group, providing safety and ease of management of the backup data. Note the ARM ID for the resource group where you wish to place the disk snapshots.

 ### Assign permissions
 
 You need to assign a few permissions via RBAC to the vault (represented by vault MSI) and the relevant disk and/or the disk RG. These can be performed via Azure portal or CLI. To assign related permissions, see the [prerequisites to configure backup of managed disks](./backup-managed-disks-ps.md#assign-permissions).
 
 ### Prepare the request to configure backup
 
-Once the relevant permissions are set to the vault and the disk, and the vault and policy are configured, we can prepare the request to configure backup. The following is the request body to configure backup for an Azure Disk. The Azure Resource Manager ID (ARM ID) of the Azure Disk and its details are mentioned in the `datasourceinfo` section and the policy information is present in the `policyinfo` section where the snapshot resource group is provided as one of the policy parameters.
