VMware CBT Requirements


This article details the requirements for Change Block Tracking (CBT).


The list of CBT requirements include:

  • ESX(i) Hosts version 4 or later
  • VM being backed up must be at least hardware version 7
  • VM being backed up cannot be configured as proxy within Veeam

More information

In versions prior to v7 the VM must have no snapshots for the first run so that CBT can be enabled. In version 7 a solution was developed that allowed the CBT function to be enabled when the VM to be backed up has a Snapshot.
