HyperV 2012 Backup and VDS/CBT Error

[agrob]

Good Day

We have an HyperV 2012 Cluster with actual 5 HyperV Hosts and SCVMM 2012. Did Register SVCMM in Veeam B&R. Did install the Veeam Components on 3hosts so far. Testing the On-Host backup at the Moment.

If i start a Job, i got the warining:
27.05.2013 10:13:12 :: Failed to flush change tracking data before snapshot. Using full scan incremental run.

At the same time on the hyperv host which act as onhost Proxy:

Log Name: System
Source: VDS Basic Provider
Date: 27.05.2013 10:13:22
Event ID: 1
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: Proxy.domain.local
Description:
Unexpected failure. Error code: 48F@01000003


-> The Backup does run, but you know, without cbt, pretty slow. Have already the latest patch installed 6.5.0.144

Any idea why this happend and how it can be solved?

What about offhost backup? would this be the better Option?

André

Andre, please contact our support team with all technical issues you have with the product as it is explained when you click New Topic. As to the off-host proxy question, then if you have shared storage then offloading backup process from the production host is indeed a better option. Thanks!

Hello!

I have the same error, but all Patches/Updates didn't help!
Latest Veeam 7.0.781 installed.
Any ideas?
Thx in advance!

so long

Leo1, since patches didn't help, then most likely you have a different problem. Your best bet would be to let our technical team investigate this issue via looking through the debug logs. Thanks!

Has this ever been sorted by anybody?

I constantly have this error in logs with ODX disabled on the server

It's been almost two and half years since the last reply in this thread, and the OP's never provided a support ticket ID. So, there is not much we can do in this situation apart from suggesting you to open a case with our support team. Thanks.

Not that it matters much, but I will open the ticket just to get it sorted

Can be bothered to spend the time on this, as in first instance I was told to just ignore the error

Maybe somebody else has more time to pursue the issue
