Registering a Cloud Siris device for use with Datto Continuity for Microsoft Azure


This article describes how to register your Datto Continuity for Microsoft Azure (DCMA) device.


  • Datto Continuity for Microsoft Azure



Special considerations

  • DCMA does not support restoration of files backed up to Azure File Sync.

  • a VM configured with Storage Spaces will back up correctly, but restores will not preserve the Managed Disk topology – each volume in Windows will become a distinct new Managed Disk.

  • Datto Continuity for Microsoft Azure supports adding up to seven Protected Systems, with up to six TB of disk space between them.

  • Datto Continuity for Microsoft Azure does not support Azure Virtual Desktop at this time or Remote Desktop Services (RDS)

  • The VM must support the Azure runCommand extension.

    • If you receive the pairing error: 'Unable to validate the virtual machine, please try again later.' and a manual test of runCommand execution fails with the error: 'RunCommandExtension failed with "'powershell' isn't recognized as an internal or external command,"', please see this article for further troubleshooting information.

  • Azure Virtual Machine Agent

    • The Microsoft Azure VM agent must be present for the push install to function. If you are migrating existing VMs into Azure from on-prem,the Azure VM agent may not properly install. See Microsoft's Azure Virtual Machine Agent overview (external link) for more information.

    • For any error encountered during agent installation, check the Windows Event Logs for any corresponding events.

    • If Visual C++ 2015 runtime is not up to date or not installed properly, this could prevent an install. Make sure that your Visual C++ runtme is up-to-date and fully-installed.

    • If you see errors related to the C++ runtime, reinstall the latest Visual C++ update.

Backups will not begin until you reboot the protected Microsoft Azure VMs.
