vSphere 6 - Incremental backups of CBT enabled VMs

Hi,

I'm testing with Backup Exec 15 the incremental backup of VMs.

The flags for "ctkEnabled" and "scsi<x>:<x>.ctkEnabled" are both set and "True", the file "*-ctk.vmdk" also exists.

There are no snapshots, the compatibility is ESXi 6.0 (VM Version 11).

The problem is that the full / incremental backups have the same size, so the incremental backups seems not to work.

Would it be possible to check whether this is a problem of VMware ?

thanks

Dirk
