Hi there,
I was wondering if someone can help. I have recently upgraded our entire Backup Exec system to 2010. We have vSphere 4 Update 1 ESXi installed on two hosts with all the latest patches installed. I have been using VMware VCB to backup 10 virtual machines across the two hosts - this creates a snapshot, takes a backup and then commits the snapshot. This has worked flawlessly for 2 years on various ESX versions including vSphere.
As VMware are removing support for VCB in the next release of vSphere I decided to purchase the VMware agent for Backup Exec. I have not been able to get a successfully backup of all of the VM's using the Backup Exec VMware agent. Out of the two full backups I have run, I receive the following error:
Unable to create a snapshot of the virtual machine. The virtual machine may be too busy to quiesce to take the snapshot.
The backup is scheduled to run at 3am in the morning - the servers are quiet and no other backups are taking place. The failure occurs on a different virtual machine each time the backup has failed - all Windows Server 2003. I can take a snapshot of the affected VM's within vCenter with no issues whatsoever.
I have patched Backup Exec 2010 to the latest version including the hot fix released on the 14th May 2010.
As VCB works flawlessly, does anyone have any idea as to why the Backup Exec VMware agent is struggling? I have the VMware tools installed in all of the VM's. I am using NBD as the transport method and GRT for individual file restore - Active Directory, Exchange and SQL GRT is disabled. The backup is going to a B2D Folder and then copied to tape.
I have a feeling it will be the case of waiting for a hot fix from Backup Exec, but just wanted to check I hadn't missed anything.
Thanks for any insight
Rob
