I have a VM with guest Windows server 2008R2 on ESXi 5.5. I am using a Netbackup to backup these VMs. while running the backup for this VM, the backup fails and when i check in the vCenter Server, the below error observed.
An error occurred while taking a snapshot: msg.snapshot.error-QUIESCINGERROR.
An error occurred while saving the snapshot: msg.snapshot.error-QUIESCINGERROR.
Please assist at the earliest.
I have been seeing this issue intermittently on a number of my servers when I have Backup Exec run a backup of the VM. I have found a solution but it is specific to Backup Exec. If I restart the Backup Exec Agent on the affected machine I can then create a snapshot without issue. I have create a scheduled task to restart this service an hour before my scheduled backup jobs. Restarting this service also kicks off the "Volume Shadow Copy Service" and the "Microsoft Shadow Copy Provider".
