 You can use [Azure Role-Based Access Control (RBAC)](../articles/role-based-access-control/overview.md) to assign specific permissions for a managed disk to one or more users. Managed Disks exposes a variety of operations, including read, write (create/update), delete, and retrieving a [shared access signature (SAS) URI](../articles/storage/common/storage-dotnet-shared-access-signature-part-1.md) for the disk. You can grant access to only the operations a person needs to perform his job. For example, if you don't want a person to copy a managed disk to a storage account, you can choose not to grant access to the export action for that managed disk. Similarly, if you don't want a person to use an SAS URI to copy a managed disk, you can choose not to grant that permission to the managed disk.
 
 ### Azure Backup service support
-Use Azure Backup service with Managed Disks to create a backup job with time-based backups, easy VM restoration and backup retention policies. Managed Disks only support Locally Redundant Storage (LRS) as the replication option; this means it keeps three copies of the data within a single region. For regional disaster recovery, you must backup your VM disks in a different region using [Azure Backup service](../articles/backup/backup-introduction-to-azure-backup.md) and a GRS storage account as backup vault. Currently Azure Backup supports data disk sizes up to 1TB for backup. Read more about this at [Using Azure Backup service for VMs with Managed Disks](../articles/backup/backup-introduction-to-azure-backup.md#using-managed-disk-vms-with-azure-backup).

Currently Azure Backup supports all disk sizes including 4TB disks. You need to [upgrade VM backup stack to V2](../articles/backup/backup-upgrade-to-vm-backup-stack-v2.md) for support of 4TB disks.
