issues using VCBmounter to backup a windows 2008 VM

[AmarPatel]

Hi,

I'm having issues using the vcbmounter command to backup a windows server 2008 R2 Standard VM. I can succesfully backup all our 2003 servers using this command.

Has anyone experienced this? is there something I need to on the OS to allow the VCB Proxy server to take the backups?

vcbMounter -h -u -p -m san -a ipaddr:[IP address of VM] -r -t fullvm

Thanks

Here's the error I get:

Hi,

Have you check if VMtools are running ?

Check in the GuestOS the Windows events to see if VSS is reported an error. You have probably install a VSS writer for a specific application ?

You can also check in the vmware.log file in the VM directory

Are you able to perform a manual snapshot for this vm?

[AmarPatel]

Yes, just performed a manual snapshot and that works fine. I can't clone the VM while running.

Also:

The VM is running windows server 2008 RS standard

I dont have update 1 installed

I have VMware ESX 4.0.0, 175625 running.

[bitbucket]

You need to have vSphere 4U1 and the according version of the VMware Tools. The version you are running does not support Windows Server 2008 R2.

[AmarPatel]

Hi,

Thank you for your response.

Yes, VM Tools are installed, there are no reported errors in the event log and no vss writer intalled for a specific application

I haven't been able to access the vmware.log file, I'll look and report back.

[AmarPatel]

Thank you, I'll look at the update notes and schedule the update.

[bitbucket · Accepted solution]

Before you are going to update just try to uninstall the VSS driver from the VMware Tools. If I remember correctly I had to do this to make VCB working with W2K8R2 before U1 has been released. I am not sure if it works but it might gives you at least a crash consistend backup.

[AmarPatel]

Thank you very much this was the solution, I have now removed the VMware VSS driver and I can now backup the 2008 VMs

I didn't need to restart the server either.

bitbucket and remi thank you for your help
