Veeam Logoby hafedh » Tue Mar 01, 2016 10:28 am

Hello everyone,

I have installed VEEAM B&R V9 and i have a Warning when i try to Backup Hyper-v Virtual Machine (This Virtual machine is in a Cluster HyperV 2008 R2);
Warning: Failed to flush change tracking data. Using full scan incremental run.
I don't have the possibility to backup this virtual machine with incremental Backup, just Full.

If a try to hyperv virtual machine (Standalone Hyperv - Not clustered), it's fine and i don't have any problem.

Can anyone help me please, thanks.

Best regards,
Hafedh

Hi,
I have a question please: One of the cluster-nodes is turned off, this can be the problem ?

Yes, CBT data is stored on each node of the cluster, and if it is turned off, then VM backup job will do a full image scan.
