More Information

If limitations on EC2 Instance Type or Azure VM Size are in place that prevent Veeam Backup & Replication from creating the Proxy Appliance, the Archive Job will fail.

For example, if the Azure VM size that Veeam Backup & Replication attempts to create is not allowed, the following error will occur:

Failed to create Microsoft Azure VM: Resource was disallowed by policy. Reasons: 'This is not an allowed Size, only approved sizes are A0, Av2, B, Dv4, Dsv4, Dv5, Dsv5, Fsv2'.
