You are either trying to back up a free VMware ESXi using Acronis Agent for ESX/ESXi or you have not added a license to your paid version of VMware ESX/ESXi

This article applies to:

• Acronis Backup & Recovery 10 Advanced Server Virtual Edition - Agent for ESX/ESXi

Symptoms

1. Using Acronis Agent for ESX/ESXi, you are trying to back up a VMware ESX/ESXi machine;
2. The backup job fails with the following error message:

   Failed to create snapshot due to license restrictions of
   ESX Server

   

Cause

There are two possible causes:

• You are trying to back up a free VMware ESXi machine;
• You have not added a ESX/ESXi license to your paid version of VMware ESX/ESXi.

Solution

Acronis Agent for ESX/ESXi does not support free VMware ESX/ESXi. See Acronis Backup & Recovery 10 Support for VMware ESX/ESXi.

If you have a paid version of VMware ESX/ESXi, make sure you have added the respective license to it.

As a workaround, you can always back up the machine using Acronis Agent for Windows or Acronis Agent for Linux, depending on the operating system of the machine. See Acronis Backup & Recovery 10 Agent.
