VCB Backup - One stubborn VM!!

I have managed to build a successful VCB infrastructure in which the majority of my virtual machines will backup nicely using VCB.

There is one holdout giving me this in the saveset report:

1 retry attempted

\[2007-03-13 10:39:39.886 'App' 4588 info] Current working directory: C:\

\[2007-03-13 10:39:40.573 'BaseLibs' 5744 warning] \[Vmdb_Unset] Unsetting unknown path: /vmomi/

\[2007-03-13 10:39:41.792 'vcbMounter' 4588 error] Error: Backup snapshot already exists.

\[2007-03-13 10:39:41.792 'vcbMounter' 4588 error] An error occured, cleaning up...

External command failed. See error above.

Exit Code: 1

*******************************************************

Networker 7.3.2 with compatibility Module

ESX 3.x

VC 3.x

guest os is windows 2k3

datastore is cx500

Anyone seen this kind of stuff with a VCB backup on one of their VM's?

Thanks,

THAT is never stupid. It's the obvious things that people always miss. Thanks for the suggestion. Here is the output from the ping testing:

Does this VM reside on its own LUN or does it share a LUN with other working VMs? Is the LUN VMFS3?

Is VMware tools installed and functioning correctly? Maybe try to uninstall and reinstall the tools?

Does it have any snapshots left over from previous attempts? If so, they'd be called something like "\_VCB-BACKUP_" or "Consolidated Helper"

[i]It shares san luns with other vm's. All my vm's do.[/i][/b]

[i]They are out of date, I will re-install tonight and try a backup tomorrow and update you with the results[/i][/b]

[b]I know about this. I deleted leftover snapshots before testing again. It leaves an orphaned snapshot every time if fails.[/b][/i]

The main thing from your message will be the updating of the vmware tools. Thanks for the suggestion!

Did reinstaling VMTools fix the problem?

No. Nothing has. What a drag! Here's the latest try:
