• Operating system: Support available only for Windows OS. Linux OS is currently not supported.
• Private endpoints: Azure trusted virtual machines can be protected using private endpoint configured recovery services vault with the following conditions:
  • You can create a new recovery services vault and configure private endpoints on it. Then you can start protecting Azure Trusted VMs using it.
  • You can't protect Azure Trusted VMs using recovery services vault which were created before the public preview and have private endpoints configured.
• Migration: Migration of Azure Site Recovery protected existing Generation 1 Azure VMs to trusted VMs and Generation 2 Azure virtual machines to trusted VMs isn't supported. Learn more about migration of Generation 2 Azure VMs.
• Disk Network Access: Azure Site Recovery creates disks (replica and target disks) with public access enabled by default. To disable public access for these disks follow these steps.
• Boot integrity monitoring: Replication of Boot integrity monitoring state isn't supported. If you want to use it, enable it explicitly on the failed over virtual machine.
• Shared disks: Trusted virtual machines with attached shared disks are currently supported.
