Azure Immutable Backups are a game-changer for data resilience. They ensure that your backups are tamper-proof and can't be altered or deleted.
Immutable backups store your data in a read-only format, making it virtually impossible to modify or delete. This means your backups are safe from accidental or malicious changes.
By using Azure Immutable Backups, you can rest assured that your data is protected and can be restored in case of a disaster.

Setting Up Immutability
You can enable immutability for a Recovery Services vault through its properties. To do this, go to the Recovery Services vault, click on Properties, and then select Immutable vault and Settings.
Immutability can be reversible at first, but once you enable the lock, it makes the immutability setting for the vault irreversible. This uses WORM (Write-Once, Read-Many) storage for backups.
To enable immutability, select the Enable vault immutability checkbox. After enabling immutability, you can select the option to lock the immutability for the vault.

Here's a step-by-step guide to enabling immutability for a Recovery Services vault:
- Go to the Recovery Services vault for which you want to enable immutability.
- On the vault, go to Properties > Immutable vault, and then select Settings.
- Select the Enable vault immutability checkbox.
- Select the option to lock the immutability for the vault.
- Select Apply to save the changes.
To enable immutability for a Backup vault, follow the same steps as for a Recovery Services vault. The process is identical, and you'll need to select the Enable vault immutability checkbox and then lock the immutability for the vault.
Understanding Immutability
Immutability is a critical concept in data protection, ensuring that your backups remain secure and tamper-proof. Azure backups in the Unitrends Cloud are stored on immutable blocks.
This means that no external source can modify or delete backups stored in the cloud. This provides an added layer of protection against ransomware and other cyber threats.
Cloud Deletion Defense offers another layer of protection, acting like a recycle bin in the cloud. This feature gives you a window of time to recover mistakenly or maliciously deleted data with the help of the cloud support team.

Azure backups offer an additional layer of protection with Cloud Deletion Defense. This feature acts like a recycle bin in the cloud, providing a window of time to recover mistakenly or maliciously deleted data with the help of the cloud support team.
Cloud Deletion Defense safeguards your data by preventing accidental or intentional deletions. It's a vital safety net for your backups.
Data Isolation with Cohesity FortKnox
Data Isolation with Cohesity FortKnox is a game-changer for cyber resilience. You can improve your cyber resilience with an immutable copy of data in a Cohesity-managed cloud vault in Azure.
Isolating your data is crucial for retention, recovery, and resiliency against ransomware. Cohesity FortKnox with Microsoft Azure helps you achieve this.
With Cohesity FortKnox, you can store an immutable copy of your data in a secure cloud vault. This ensures that your data remains intact even in the face of ransomware attacks.
Cohesity FortKnox is designed to work seamlessly with Microsoft Azure, providing an additional layer of security for your data.

Managing Immutability
To enable immutability for a vault, you can follow the steps outlined in the Azure documentation. This involves going to the vault's properties, selecting the Immutable vault settings, and enabling the vault immutability checkbox.
Once you enable immutability, the option to lock the immutability for the vault appears. This lock makes the immutability setting for the vault irreversible and uses WORM (Write-Once, Read-Many) storage for backups.
You can test and validate how the current settings of the vault, backup policies, and so on, meet your requirements before locking the immutability setting. This is a crucial step, as locking immutability is an irreversible action.
Here's a quick summary of the steps to enable immutability for a Recovery Services vault:
- Go to the Recovery Services vault for which you want to enable immutability.
- On the vault, go to Properties > Immutable vault, and then select Settings.
- Select the Enable vault immutability checkbox to enable immutability for the vault.
- Once you enable immutability, the option to lock the immutability for the vault appears.
Note that the steps for enabling immutability for a Backup vault are similar, but slightly different.
Disable Immutability
Disabling immutability is a straightforward process that allows you to reverse the immutability setting for your vault. You can only disable immutability for vaults that have immutability enabled but not locked.
To disable immutability for a Recovery Services vault, go to the vault's properties and select the Immutable vault settings. Clear the Enable vault Immutability checkbox and select Apply to save the changes.
For Backup vaults, the process is identical. Go to the vault's properties, select the Immutable vault settings, clear the Enable vault Immutability checkbox, and select Apply to save the changes.
It's worth noting that disabling immutability will not delete your backup data, but it will make the data accessible for modification. If you've already locked the immutability setting, you won't be able to disable it.
Here's a quick summary of the steps to disable immutability for both Recovery Services and Backup vaults:
By following these simple steps, you can disable immutability for your vault and regain control over your backup data.
Perform Restricted Operations
Immutability in vaults can be restrictive when trying to modify policies. You can't reduce retention of daily backup points if the vault has immutability enabled.
Trying to modify a policy to reduce retention will fail with an error message. This is because any changes that could reduce retention of recovery points are disallowed.
Increasing retention of daily backup points is allowed if it doesn't involve deleting any recovery points. However, if you're increasing retention of backup items in a suspended state, it's not supported.
Trying to update a policy to increase retention of daily backup points while the backup is in a suspended state will fail. The error message will prevent you from modifying the policy.

Frequently Asked Questions
What is the difference between air-gap and immutable backups?
Air-gapping isolates data from the network, while immutable storage prevents backups from being altered or deleted, offering distinct protection against unauthorized access and ransomware attacks.
Can you delete immutable backups?
Immutable backups cannot be deleted directly. Contact Azure technical support for assistance with deletion.
