Restoring a VM does not work for which type of Azure VM?

Restoring an Azure Virtual Machine (VM) that is encrypted can be complex due to the nature of encryption mechanisms. When Azure Disk Encryption is enabled on a VM, it protects the data at rest by encrypting the VM's disks. In the event that a restore operation is initiated, the restoration process may not function properly if the required decryption keys are not accessible or if the encryption context is not correctly configured. In many cases, additional steps are needed to ensure that the VM is properly decrypted and that the keys are managed securely during the restore process.

This complexity sets encrypted VMs apart from other types of VMs when it comes to the restoration process. Other VM types like temporary VMs, VMs with multiple disks, or standard Azure VMs typically do not face the same level of complication during restoration because they do not have the added layer of encryption, making them more straightforward to restore using Azure's built-in capabilities.
