Generally available: Immutable vaults for Azure Backup

Immutable vaults, now generally available, provide improved security for your backups by ensuring that recovery points that are once created cannot be deleted before their intended expiry time. Azure Backup does this by preventing any operations on immutable vaults which could lead to loss of backup data. Furthermore, you can lock the immutable vaults property to make it irreversible. Hence, this helps you protect your backups against threats like ransomware attacks and malicious actors by disallowing operations such as deleting backups or reducing retention in backup policies.
