Changed block tracking cannot be enabled: one or more snapshots are present

Challenge

After upgrade to Veeam Backup & Replication 10, Backup from Cisco HyperFlex Snapshots job completes with the warning "Changed block tracking cannot be enabled: one or more snapshots are present" if Sentinel snapshot is already present.

Cause

Veeam Backup & Replication does not enable CTK during backup from Cisco HX for vSphere 6.5 and later hosts as in this case VMware might return incorrect CBT data.

Solution

As a workaround, please add the following registry key on the server where the Veeam Backup & Replication is installed:
Path: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication
Type: DWORD
Name: VMware65CbtSnapshotCheckEnabled
Data: 0
KB ID:
