Here’s a quick tip for you in case you’re using Microsoft Azure Backup for infrastructure as a service (IaaS) and a scheduled VM backup fails with the following error message in the job error details in the Azure Portal:
Could not communicate with the VM agent for snapshot status - Snapshot VM sub task timed out.
There are four common causes for this error:
The VM does not have Internet access.
The Microsoft Azure VM agent installed in the VM is out of date (for Linux VMs).
The backup extension failed to update or load.
The snapshots status cannot be retrieved or the snapshots cannot be taken.
