Check if VMware CBT settings are properly configured for the VM:
Check .vmx file of the VM and make sure that the following options are present:NOTE: if
ctkEnabled = "TRUE"
scsi0:0.ctkEnabled = "TRUE"
Note title Note
If the VM has multiple disks, this option must be present for each disk.
- Check the VM folder on the datastore. Make sure that there is the -CTK.VMDK file for each disk.
Several factors – such as a power outage – can cause VMware CBT to reset and lose a track of incremental changes for a VM.
