Error msg.snapshot.error-QUIESCINGERROR during a VM backup

Hi! While some VMs' backup, I'm getting the following error at Vcenter:

An error occurred while taking a snapshot: msg.snapshot.error-QUIESCINGERROR.
An error occurred while saving the snapshot: msg.snapshot.error-QUIESCINGERROR.

Then, the backup job for this particular VM fails at Data Protector:

    Virtual Machine 'SERVERNAME': Creating snapshot ...

Thanks for your help.

Re: Error msg.snapshot.error-QUIESCINGERROR during a VM backup

Hello JoaoCorrea,

This is usually caused by the VM itself. You request a VSS quiescence this could fail for various reasons such as the VM is not running Windows or is missing the VMware Tools. Or there could be simply a VSS error inside the VM (check Windows event logs). If any of those applies you can disable quiescing globally or per-VM basis.

Hi Sebastian!

Thank your very much for your help. It worked when I disabled quiescing globally in the DP. Backups went well from now on.

Thanks again,

Joao Correa.
