Bug CBT vSphere 8.0U2

Hi,

Is Backup Exec 22.x impacted by CBT bug in vSphere 8.0 U2 ?

QueryChangedDiskAreas API returns incorrect sectors after extending virtual machine VMDK file with Changed Block Tracking (CBT) enabled in ESXi 8.0u2 (95940)

https://kb.vmware.com/s/article/95940

vSphere 8.0 U2 restored file corruption with resized VM disks (95965)

https://kb.vmware.com/s/article/95965

I think yes, do you have an workaround like Veeam (add registry key)

Thanks for your response.

        The KBs you posted from VMware mentioned when you extend or resize VD.

        If you don't have any problem, I dont suggest that you make any change.
