Incremental backup of Virtual Machines may generate ANS9384W.
When "backup vm" command is executed with "mode=Incremental", the backup command may become
full backup and then generate ANS9384W message.
ANS9387W Incremental backup unsuccessful for virtual machine 'Node01'. Performing Full backup instead.
ANS9384W Unable to get VMware Changed Block Tracking(CBT) data for virtual machine 'Node01'.
Full VM backup continues, and includes both used and unused areas of the disk.
There can be 2 causes of this warning message:
1: This is normal if this is the first backup of this guest machine.
2: Change Block Tracking is not enabled or supported for this guest machine.
Resolving the problem
To enable Change Block Tracking,
please set "ctkEnable true" and "scsiX:X.ctkEnabled true" against target disk in Configuration Parameters in Virtual machine Properties. (X:X means actual target disk such as 0:0, 0:1 and so on.)
