  1. You try to enable application-aware backup of ESXi virtual machine,
  2. Operation fails with the following error:

Failed to get the object's property 'disk.EnableUUID'


The 'disk.EnableUUID' parameter is not set in the virtual machine options in VMware vSphere. This parameter is required to present a consistent UUID to the VM, thus allowing the disk to be mounted properly.


Enable "disk.EnableUUID" parameter for the affected virtual machine:

  1. Power off the VM
  2. Select the VM and choose Edit Settings.
  3. Select the Options tab on top, then select General under the Advanced section.
  4. Select Configuration Parameters... on the right side.
  5. Check to see if the parameter disk.EnableUUID is set, if it is there then make sure it is set to TRUE.
  6. If the parameter is not there, select Add Row and add disk.EnableUUID parameter with value = TRUE

More information

The ‘Disk.EnableUUID’ property must be set to ‘True’ in order to enable application-consistent quiescing of the VM during the snapshot creation. Successful application-consistent VM snapshot which is a ”must” pre-requisite for proper application-aware processing of the backup. See this VMware article for more details about types of consistency within VMware snapshots.
