Hello
I have a vmware environment and I am using TSM for VE 6.4 for backup every new
machine added to vmware I configure the Changed Block Tracking(CBT) to true as
ctkEnabled: True
The first backup I run for the virtual machine even the CBT is ON I got the
message:
05/29/2013 08:09:01 ANS9384W Unable to get VMware Changed Block Tracking(CBT)
data for virtual machine 'mdb2'. Full VM backup continues, and includes both
used and unused areas of the disk.
The problem is that we are using the feature of Thin provisioning by giving
more disk capacity, so in my example:
Have a disk name : Hard disk 2 Provisioned Size: 1.6 TB
We have around 100GB data on this disk . but when running the first backup got:
Processing snapshot
disk: [netapp-moodle-4500] mdb2/mdb2.vmdk (Hard Disk 2)
Capacity: 1,610,612,736,000
Data to Send: 1,610,612,736,000
Transport: (hotadd)[sending]
I thought even is the first backup it will still backup only 100GB and not the
full provisioned size 1.6T !
I miss obviously something ?
Regards Robert
