VMWare image backup with Block Level Incremental
All,
I tried configure BLIB with NetBackup 7.5.0.3, vSphere 5, vmware hardware version 8 (vmx-08) with VMFS 5. Technically BLIB should backup less data in Incremental backup but its reverse in this case. I did configure total of 20 Servers in two different policies one with BLIB enable and other is regular and below are the stats for 5 consecutive incremental backups
BLIB VMWare Incr:- 205 GB
Regular VMWare Incr:- 162 GB
Need your suggestion which to go with for VMX-08 VMs. BLIB or Regular ?

Have you already tried disabling and enabling CBT?If not, consider to try as below.1) Shutdown VM2) remove all snapshot of VM3) remove CBT setting4) remove *-ctk.vmdk files on datastore5) enable CBT for both VM and vmdk6) power on VM7) take full backup8) take diff backupeventually the forum poster reported a fix made available in 7.5.0.3.But worth the deleting of CTK files to in case CBT failed to identify Changed data Blocks
