An error message is stating that the source VMware host did not provide valid CBT data for a VM and that the proprietary change tracking technology will be used.
After the initial (full) VM backup or replication, all consequent job runs are forever incremental.
By default, NAKIVO Backup & Replication uses VMware CBT or Hyper-V RCT technologies to identify what data has changed since the last job run.
Several factors – such as a power outage – can cause VMware CBT to reset and lose a track of incremental changes for a VM.
The above error message appears in case the CBT/RCT error handling is set to switch proprietary change tracking technology.
You can also reset CBT for the VMware VM manually.
