ISSUE:"Reason = "UUID conflict on Virtual Machine." error is shown on VMware ESXi backup job

Article ID: 5244
Reviewed: 09/06/2017

Product Version:
AhsayOBM: or above
OS: Windows

Problem Description

When performing a VMware ESXi backup job following warning is shown in the backup log:

No. Type Timestamp Log
* ... ... ...
* erro YYYY/MM/DD hh:mm:ss Skip update from backup source "$guestVM$". Reason = "UUID conflict on Virtual Machine. "$guestVM$""
* info ... ...


The "UUID conflict on Virtual Machine." error is returned by the VMware host.

This indicates there is another guest virtual machine with duplicate UUID running on this VMware host. This situation could arise if the guest virtual machine was copied or cloned from another VMware host or datastore. VMware cannot run guest virtual machines with duplicate UUID's on the same VMware host



UUID, copied, cloned, VMware ESXi, duplicate
