Problem with Backup in ESXI6.0 (invalid CBT data)

[cyrilleb]

Hi,

We have a problem since we upgrade to ESXI 6.0

Many Backups have these error in Veeam : invalid CBT data

After search i find a kb in vmware : VMware KB: Backing up a virtual machine with Changed Block Tracking (CBT) enabled fails after upgrad...

And i install the good patch yesterday.

But this night we have the same problem and my question is :

Do that backup need to turn one time after patch with error forautomatically reset the CBT?

thank you for your help.

I believe this Veeam KB may be helpful.

Finally at the second backup job all is good.

I think after install patch you need to have a first backup with CBT Error for reset CBT .
