 ## Create a Backup vault
 
 Backup vault is a storage entity in Azure that stores backup data for various newer workloads that Azure Backup supports, such as Azure Database for PostgreSQL servers, blobs in a storage account, and Azure Disks. Backup vaults make it easy to organize your backup data, while minimizing management overhead. Backup vaults are based on the Azure Resource Manager model of Azure, which provides enhanced capabilities to help secure backup data.

 If you require application-consistent backup of virtual machine including the data disks, or an option to restore an entire virtual machine from backup, restore a file or folder, or restore to a secondary region, then use the [Azure VM backup](backup-azure-vms-introduction.md) solution. Azure Backup offers side-by-side support for backup of managed disks using Disk Backup in addition to [Azure VM backup](./backup-azure-vms-introduction.md) solutions. This is useful when you need once-a-day application consistent backups of virtual machines and also more frequent backups of OS disks or a specific data disk that are crash consistent, and don't impact the production application performance.

 - When you configure backup, the disk selected to be backed up and the snapshot resource group where the snapshots are to be stored must be part of the same subscription. You can't create an incremental snapshot for a particular disk outside of that disk's subscription. Learn more about [incremental snapshots](/azure/virtual-machines/disks-incremental-snapshots#restrictions) for managed disk. For more information on how to choose a snapshot resource group, see  [Configure backup](backup-managed-disks.md#configure-backup).
 
 - For successful backup and restore operations, role assignments are required by the Backup vault’s managed identity. Use only the role definitions provided in the documentation. Use of other roles like owner, contributor, and so on, isn't supported. You may face permission issues, if you start configuring backup or restore operations soon after assigning roles. This is because the role     assignments take a few minutes to take effect.
 
-- Managed disks allow changing the performance tier at deployment or afterwards without changing size of the disk. The Azure Disk Backup solution supports the performance tier changes to the source disk that is being backed up. During restore, the performance tier of the restored disk will be the same as that of the source disk at the time of backup. Follow the documentation [here](/azure/virtual-machines/disks-performance-tiers-portal) to change your disk’s performance tier after restore operation.

 - [Private Links](/azure/virtual-machines/disks-enable-private-links-for-import-export-portal) support for managed disks allows you to restrict the export and import of managed disks so that it only occurs within your Azure virtual network. Azure Disk Backup supports backup of disks that have private endpoints enabled. This doesn't include the backup data or snapshots to be accessible through the private endpoint.
