Challenge
This article details the requirements for Change Block Tracking (CBT).
Solution
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 a proxy within Veeam
You can find more information about Changed Block Tracking in the user guide.
More information
Starting with Veeam Backup & Replication 7, VMware native CBT can be enabled when a VM has a snapshot present. However, in some rare situations, it may still be possible to get the warning "Changed block tracking cannot be enabled: one or more snapshots are present," in that case, you should remove all VMware Snapshots from the VM.
