Incremental backup promoted to a full after a live migration failure for a Hyper-V VM


This article explains why incremental backups are promoted to full backups after a live migration failure.


If a live migration for a Hyper-V VM fails but the owner node changes, the Hyper-V CBT driver cannot compare changes on the VM with its snapshot entries.  As a result, the next incremental backup is promoted to a full.  Subsequent incremental backups run as scheduled.
