Hi Ranjit Singh,
Thanks for reaching out to Microsoft Q&A.
The option to enable immutability for Recovery Services vaults is typically only available for newly created vaults and may not be accessible for older, existing vaults. Microsoft currently restricts this setting to ensure that it is set at the time of vault creation, and it cannot be retroactively applied to an existing vault due to design constraints aimed at maintaining data integrity and security.
If you need immutability for compliance or data protection reasons, consider the following options:
Create a New Recovery Services Vault:
Set up a new vault with immutability enabled and start directing new backups to it. Migrate Data:
Migrate your backup data to the new vault if feasible. Note that this may require reconfiguration of your backup policies and may incur some downtime. Check for Policy Updates:
Microsoft Azure frequently updates its services, so it's worth checking the Azure updates page or contacting Microsoft support to confirm if any recent changes allow immutability on existing vaults. If immutability is critical for your existing setup, contacting Azure Support may provide additional options or guidance specific to your configuration.
