Protecting Hyper-V VMs with Resilient Change Tracking
This recipe covers how to protect a Hyper-V VM with Resilient Change Tracking (RCT).
Getting ready
Starting with Windows Server 2016, Microsoft introduced built-in change tracking for Hyper-V virtual hard disks known as RCT. As a result, in the case of a Hyper-V host outage, or VM migration, change tracking is automatically preserved.
System Center 2016 Data Protection Manager or later will take the benefit of this feature when protecting Hyper-V VMs running on Windows Server 2016 with configuration version 8.0 and later.
With RCT, DPM backups benefit as follows:
- More reliable: Consistency Checks (CC) aren't required after a VM migration
- Scalable: More parallel backups and less storage overhead
- Improved performance: Lower impact on the production fabric and faster backup

How to do it...
Hyper-V VMs, deployed on Windows Server 2016 or Windows Server 2019 and protected using DPM 2016 or later, have RCT by default. VMs deployed on Windows Server...
