Hi seanz123,
Set in the client properties == apps&modules == application information field variable:
VADP_DISABLE_CBT=NO

Hi seanz123,
FYI,,
EMC® NetWorker and VMware Integration Guide Release nw8.1
Task 4: Configuring Changed Block Tracking (CBT)
You can check if your virtual machine has CBT enabled or enable/disable CBT by setting
the variable VADP_DISABLE_CBT, or by using the command line executable,
nsrvadp_modify_vm.exe.
Note: When Changed Block tracking (CBT) is enabled, incremental and differential
backups are supported only for Windows VMs, and all attached disks must be NTFS file
systems.
Note also that CBT-based incremental backups are always file based. Image level recovery
from a CBT-based incremental backup is not supported.
Configuring CBT using the variable VADP_DISABLE_CBT
Setting the variable VADP_DISABLE_CBT allows you to control the enabling or disabling of
CBT. This option is available in NetWorker 8.0 SP1 and later.
Setting VADP_DISABLE_CBT = YES disables CBT. CBT will not be used for incremental
backups.
Setting VADP_DISABLE_CBT = NO enables CBT prior to performing image backups.
Handling of FLR based incremental backups does not change.
Note: If VADP_DISABLE_CBT is not configured, no attempt is made to enable CBT before
performing image backups. Handling of FLR based incremental backups does not change.
