+## Immutable vault for Azure Backup is now generally available
+
+Azure Backup now supports immutable vaults that help you ensure that recovery points once created can't be deleted before their expiry as per the backup policy (expiry at the time at which the recovery point was created). You can also choose to make the immutability irreversible to offer maximum protection to your backup data, thus helping you protect your data better against various threats, including ransomware attacks and malicious actors.

+For more information, see the [concept of Immutable vault for Azure Backup](backup-azure-immutable-vault-concept.md).

 ## Support for selective disk backup with enhanced policy for Azure VM (preview)
 
 Azure Backup now provides *Selective Disk backup and restore* capability to Enhanced policy. Using this capability, you can selectively back up a subset of the data disks that are attached to your VM, and then restore a subset of the disks that are available in a recovery point, both from instant restore and vault tier.
