Veeam and VCB issue

[digex]

I have setup VCB on a Windows machine that I already had Veeam Backup 3.1.1 installed. I run the back with Veeam in VCB support mode and it completes as said in the job history but shows that it backed up only 0KB. Do I have to reinstalled Veeam Backup 3.1 since I installed VCB after the fact? Yes I have dismount disabled, but multipath is enabled and is supported by VCB 1.5.

Hello, no, this is not needed - Veeam Backup is not picky about VCB installation order.
We would like to investigate the logs, could you please shoot them over to support@veeam.com?
