If VMware CBT is chosen, you can configure two more checkboxes:
Enable Changle Blocks Tracking in VMware for all virtual machines selected to backup - if this checkbox is enabled, CBT will be used for all protected virtual machines.
Reset CBT every full copy - if this checkbox is enabled, CBT will be reset every full copy execution. Due to the fact, that CBT leaves flags on the point, where the last change was done, you can reset these flags using this checkbox.
