VMware Backups Failing with Error UUID Not Found

SUMMARY

To inform customers about VMware Backups failing due to UUID not found error.

ISSUE

A VMware Backup of a Virtual Machine (VM) fails with the error -

“VM with UUID xxx-xxx-xxxxxxxxxxx not found”

For more detailed information on backup failures and performance issues see Unitrends KB 5062 - Backup Failures and Performance Issues

RESOLUTION

The steps below are for the legacy UI, to perform an inventory sync in our current UI please reference this KB

For Recovery Series/UEB appliances:

On the Backup > 1-Time Backup or Backup > Schedule Backup page, click on the ‘Reload VMs’ button. This will get the latest information from the vCenter Inventory and will keep Unitrends’ Database in sync with that of the vCenter/ESX server.

For Unitrends Free:

On the Protect page, click on the ESX/vCenter server where the Backups of VMs are failing. Then, on top, click on Options and then on Inventory Sync. This will get the latest information from the vCenter Inventory and will keep Unitrends’ Database in sync with that of the vCenter/ESX server.

CAUSE

Unitrends uses a Virtual Machine’s UUID for identification. This is as per the guidelines provided by VMware. A VM’s UUID can change if it is removed from inventory and then added back again or manual migration of a VM from one ESX Server to another.
